This in turn has the potential of enabling and improving cultivation practices in coastal lands affected by salt stress. Methods Endophytic fungi from the wild halophytic rice Oryza coarctata were isolated, characterized, identified, and studied for their effects on all developing stages of rice plant growth and their yields both with and without salt stress. Key results In this study, three different fungal endophytes were isolated from the halophytic wild rice Oryza coarctata . Two isolates were identified as Talaromyces adpressus (OPCRE2) and Talaromyces argentinensis (OPCRh1) by ITS region sequencing. The remaining isolate NPCRE2 was confirmed as a novel strain named Aspergillus welwitschiae Oc streb1 ( AwOc streb1) by whole genome sequencing. These endophytes showed various plant growth-promoting (PGP) abilities in vitro (e.g., IAA, ACC-deaminase and siderophore production, phosphate, and zinc solubilization as well as nitrogen fixation), where AwOc streb1 was significantly more efficient compared to the other two isolates at high salinity (900 mm). Independent application of these fungi in commercial rice ( Oryza sativa ) showed significant elevation in plant growth, especially in the case of the AwOc streb1 inoculants, which had enhanced metabolite and chlorophyll content at the seedling stage in both no-salt control and 100-m m salt-stressed plants. At the same time, AwOc streb1-treated plants had a significantly lower level of H 2 O 2 , electrolyte leakage, and Na + /K + ratio under saline conditions. Higher expression (1.6 folds) of the SOS1 (salt overly sensitive 1) gene was also observed in these plants under salinity stress. This strain also improved percent fertility, tillering, panicle number, and filled grain number in both no-salt control and 45-m m salt-stressed inoculated plants at the reproductive stage. Consequently, the differences in their yield was 125.16% and 203.96% ( p < 0.05) in colonized plants in normal and saline conditions, respectively, compared to uninoculated controls. Conclusions We propose that AwOc streb1 is a potential candidate for an eco-friendly biofertilizer formula to improve the cultivation and yield of rice or any other crop in the highly saline coastal regions of Bangladesh.","PeriodicalId":8069,"journal":{"name":"Annals of Microbiology","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135766633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods and results In this study, a novel combination of UASB followed by aerobic treatment has been proposed for the treatment of municipal wastewater focusing on bacterial communities using high-throughput sequencing and parasite removal in this novel combination of reactors. Moreover, economic estimation of the compact unit composed of two overlapping UASB reactors, followed by a downflow hanging non-woven fabric (DHNW) reactor, the anaerobic baffled reactor (ABR), and chlorine unit was investigated in this study based on community populations of 1000 and 10,000 inhabitants, with a municipal plant capacity of 54,000 and 540,000 m 3 /year. Cost estimation was conducted based on two scenarios, one considering the contingency cost and auxiliary facility, and the other excluding them. Non-metric multidimensional scaling (nMDS) revealed that the treatment stages structured the microbial communities. Proteobacteria was the most prevalent phylum in all treatment stages, followed by Bacteroidota in most stages. Firmicutes and Actinobacteria were also present in significant amounts. The treatment system achieved from 40 to 66.67% removal of parasites (parasitic nematode, Cryptosporidium , and microsporidia). Redundancy analysis (RDA) indicated a strong positive correlation between chemical and biological oxygen demand (COD/BOD) with Campylobacterales and could be used as a bioindicator of treatment performance.

Global maize productivity has decreased significantly due to sudden temperature fluctuations and heat waves especially in the regions severely hit by climate change. Results The current study demonstrates the potential of beneficial bacteria for inducing heat tolerance in maize during early growth. Three Bacillus spp . AH-08, AH-67, SH-16, and one Pseudomonas spp . SH-29 showed the ability to grow and exhibited multiple plant-beneficial traits up to 45 ± 2 °C. At temperatures of 45 and 50 °C, Bacillus sp. SH-16 exhibited upregulation of two small heat shock proteins (HSP) of 15 and 30 kDa, while SH-16 and AH-67 showed upregulation of two large HSP of 65 and 100 kDa. Plant-inoculation with the consortium B3P (3 Bacillus + 1 Pseudomonas spp.) was carried out on six hybrid maize varieties pre-grown at 25 ± 2 ºC. Heat shock was applied to 10-day-old seedlings as: 3 h at 38ºC, 48 h recovery period, and then 48 h at 42ºC. The B3P treatment showed significant improvement in the overall plant growth (plant height, root &amp; shoot fresh &amp; dry weight, root and leaf area) with a higher level of CAT, POD, total chlorophyll, and carotenoids, while low concentration of MDA. A non-significant difference was observed in case of total cell protein and amino acids after B3P-treatment under stress. The expression of HSP1 and HSP18 in Malka and YH-5427 while HSP70 and HSP101 were higher in FH-1046 and Gohar as compared to non-inoculated treatment. Conclusions These findings indicate that heat-tolerant plant-growth promoting rhizobacteria (Ht-PGPR) exert versatile, multiphasic and differential response to improve plant growth and heat-tolerance in different maize varieties during seedling/ early vegetative growth. Subsequent research will be focused on the field evaluation of these PGPR to see the field and yield response of this consortium under natural temperature fluctuations in field.","PeriodicalId":8069,"journal":{"name":"Annals of Microbiology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135342806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of P. hysterophorus invasion on the local environment became increasingly critical, while few information was available for the effects of P. hysterophorus invasion on soil bacteria. The present study aimed to reveal the impacts of hysterophorus on the fungal communities in the Yellow River Delta. Methods Sixteen soil samples including four groups (ROOT group, YRR group, YNR group, and GBS group) were collected. High-throughput methods were used to explore the fungal composition of the P. hysterophorus -invaded surrounding environment and native plant-growed environment. Results Our results showed that the ACE (351.97) and Chao1 (351.95) values of the rhizosphere soils of P. hysterophorus (YRR group) were the highest among the four groups, whereas the non-rhizosphere soil samples of P. hysterophorus (YNR group) had the highest Shannon (7.188) and Simpson (0.984) values. The total number of operational taxonomic units (OTUs) obtained from the four groups was 1965, with 161 common OTUs among different groups. At the phylum level, both Ascomycota and Basidiomycota were the dominant fungi, with Ascomycota having the highest abundance. At the genus level, except for the endophytic fungi of P. hysterophorus roots (ROOT group), Fusarium , Mortierella , Comoclathris , and Cladosporium were the dominant fungi in three groups. The fungal communities within the roots of P. hysterophorus were distant from other groups, indicating that the composition of the fungal communities within the roots had a low degree of similarity to the other three groups. LEfSe analysis showed that Ascomycota at the phylum level and Cladosporium , Curvularia , and Alternaria at the genus level play essential roles in the ROOT group, and Comoclathris plays a vital role in the YNR group. Conclusions This study explored the effects of P. hysterophorus invasion on the local soil fungal communities by analyzing the fungal communities in P. hysterophorus roots , rhizosphere soil, non-rhizosphere soil, and rhizosphere soil of native plants. Generally, P. hysterophorus rhizosphere fungi specifically affect the surrounding environment.","PeriodicalId":8069,"journal":{"name":"Annals of Microbiology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136308717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite ensuring certain economic advantages, they have also resulted in issues like environmental contamination, declining soil quality, and pesticide residues. Because biological control is environmentally friendly and difficult to acquire resistance to, it has been used in practice recently. Methods In this study, we isolated the endophytic fungus Purpureocillium lilacinum from Portulaca oleracea L . , which was previously found to have inhibitory effects on soil pathogens in tobacco fields. To find out how the biocontrol agent P. lilacinum affects soil microorganisms and plant metabolism in tobacco cultivation, we used amplicon sequencing technology and gas chromatography-mass spectrometry to look at the structure of soil microbial communities and the networks of interactions between microorganisms and metabolites in the inter-rhizosphere soil of tobacco fields treated with different amounts of P. lilacinum . Results The findings showed that there was a trend toward less microbial diversity among inter-root microorganisms as solid-state fermentation (SSF) products of P. lilacinum increased; however, submerged fermentation (SmF) had no discernible impact on microbial diversity when compared to the direct use of SSF. Additionally, the relationship between inter-root fungi and volatile compounds in tobacco leaves was dominated by a negative correlation. Conclusions The result demonstrated that P. lilacinum ’s antagonistic interaction in the inter-rhizosphere microbial community was dominant and valuable for biopesticide application. P. lilacinum can work more effectively on tobacco roots by using SSF products. P. lilacinum ’s opposition to fungal colonies may enhance the volatile chemicals in tobacco leaves.

The volatile fatty acids (VFAs) and microbiota present in the digestive tracts of cows can contribute to cow health. Here, we exploratorily investigated the VFAs and microbiota in the rumen and gut with respect to subclinical BLV infection using cows housed at a single farm. Results We analyzed a herd of 38 cows kept at one farm, which included 15 uninfected and 23 BLV-infected cows. First, the analysis of the VFAs in the rumen, gut, and blood revealed an absence of statistically significant differences between the uninfected and BLV-infected groups. Thus, BLV infection did not cause major changes in VFA levels in all tested specimens. Next, we analyzed the rumen and gut microbiota. The analysis of the microbial diversity revealed a modest difference between the uninfected and BLV-infected groups in the gut; by contrast, no differences were observed in the rumen. In addition, the investigation of the bacteria that were predominant in the uninfected and BLV-infected groups via a differential abundance analysis showed that no significant bacteria were present in either of the microbiota. Thus, BLV infection possibly affected the gut microbiota to a small extent. Moreover, bacterial associations were compared between the uninfected and BLV-infected groups. The results of this analysis suggested that BLV infection affected the equilibrium of the bacterial associations in both microbiota, which might be related to the BLV-related negative effects. Thus, BLV infection may negatively affect the equilibrium of bacterial associations in both microbiota. Conclusions Subclinical BLV infection is likely to affect the rumen and gut microbiota, which may partly explain the BLV-related negative effects.","PeriodicalId":8069,"journal":{"name":"Annals of Microbiology","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135308611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resistance to Carbapenems is mainly associated with enzyme-mediated resistance mechanism, through the acquisition of Carbapenemase genes. In Uganda, no studies have been done to detect presence of Carbapenem-resistant E. coli in sewage. We therefore carried out a study to characterize Carbapenem-resistant E. coli from sewage from Mulago National Referral Hospital. Methods and results In this cross-sectional study, a total of 104, sewage samples were aseptically collected, cultured on MacConkey agar supplemented with Meropenem 1 µg/ml with other standard microbiology methods to screen for Carbapenem-resistant E. coli (CREC). Antimicrobial susceptibility testing was performed on the CREC, using Imipenem (10 mg/disc) and Meropenem (10 mg/disc), Carbapenem drugs readily available on market. Multiplex PCR was performed on selected Carbapenem-resistant and susceptible isolates to detect Carbapenemase genes. Later the isolates were pathotyped for virulence genes that included pathogenicity islands (PAIs) and phylogenetic markers. The results showed that the Carbapenem-resistant E. coli isolates were more resistant to Meropenem (64%) than Imipenem (60%). KPC gene was the most predominant (75%), followed by NDM gene (30%) while no OXA-48, IMP-1, and IMP-2 genes were detected. Pathotyping of virulence genes showed presence of eae gene, as the most predominant (40%), followed by elt gene (25%) and negative for stx and aggR genes. For PAI markers, only the PAI IV 536 gene was detected at 10%. Then, pathotyping of the phylogenetic markers was present in 85% of the typed isolates with yjaA gene the most abundant (60%) while both chuA and TSPE4.C2 were detected in 5% of the isolates.
