Nitrofurazone is widely applied in poultry and aquaculture veterinary drugs. Without appropriate treatment, nitrofurazone residue from agriculture animal waste may have a negative impact on microorganisms. Thus, a study to enhance nitrofurazone degradation using local Aspergillus tamarii KX610719.1 was explored by optimizing the selected parameters. The specific aims of the exploration were: 1) to optimize parameters (pH, temperature and agitation speed) for nitrofurazone degradation rate, 2) to determine the nitrofurazone residue using a High-Performance Liquid Chromatography-diode array detector (HPLC-DAD), 3) to verify the optimum parameters performance in degrading nitrofurazone. Response Surface Methodology (RSM) based on Central Composite Design (CCD) was employed to analyze and optimize the effect of parameters as independent parameters on the nitrofurazone degradation rate as the response function. The interaction effects and optimum parameters were obtained using Design Expert Version 13.0 software (Stat Ease, Inc., Minneapolis, USA). The adequacy of the model test was determined using statistical analysis of variance (ANOVA) with a 95% confidence level, which demonstrated satisfactory agreement between the experimental data and the predicted model. The results demonstrate that the optimum conditions for nitrofurazone degradation rate were at the pH value (4.80), temperature (35.84 ºC) and agitation speed (121.33 rpm) with a coefficient of determination, R2 of 0.9612. Based on the verification process, the actual and predicted results was did not significantly differ (P <0.01). A. tamarii KX610719.1 showed a great ability in degrading nitrofurazone under optimum parameters.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84856824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They have remarkable efficiency and specificity. They have been widely used in many industrial processes such as food processing, beer fermentation, laundry detergents, pickling purposes, and work as biomarkers for various health conditions. One of the commercially important enzymes is choline oxidase. It belongs to the oxidoreductase family. Oxidoreductases catalyze the transfer of electrons, from electron-donating molecules (reductants) to electron-accepting molecules (oxidants). The current review is focused on the understanding of the wider range of applications of choline oxidase. Choline oxidase plays a key role in the development of resistant transgenic plants against salt, drought, salinity, and low temperature. This enzyme catalyzes the reaction between choline and betaine glycine. Betaine glycine is an osmoprotectant and instrumental in helping plants and bacteria survive dry conditions. Choline oxidase helps in the determination of mustard agents. This insight has helped in devising sensors and developing bioassays for the determination of mustard agents in contaminated environmental sites. Betaine glycine inhibits the growth of cancer cells in vitro. Betaine intake as a nutrient is helpful in the management of good liver, kidney, and heart health. Feeding broiler chicken with choline and betaine glycine as dietary supplements, had a huge positive impact on weight gain, feed efficiency and consumption, and as well as on mortality. Choline oxidase has been engineered for the potential application as biological bleach in detergents. Choline oxidase is having a promising future as an industrial enzyme.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86732060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Microbial biofilm presents a critical medical challenge as a result of they are recalcitrant to current therapeutic regimes. One of the distinctive features of bacterial biofilms is an enhanced resistance and tolerance to antibiotics. Compared to the planktonic community, bacterial cells inside the biofilms have proven to be a thousand times more tolerant to standard antibiotics and are resistant to the natural defence mechanism by the host, making them highly difficult to remove.

The present study aimed to investigate the antagonistic activity of Trichoderma harzianum and Pleurotus ostreatus isolates against Fusarium spp., the causative agents of wilt disease in cucumber plants, through a dual plate assay of volatile and nonvolatile compounds from these bioagent fungi. The results showed significant (P < 0.05) antagonistic activities of T. harzianum against the growth of F. solani AJA2 (62.3%), followed by F. oxysporum AJA (55.2%), F. incarnatum AJA (53.2%), and F. solani AJA1 (50.8%). The effectiveness of P. ostreatus against the four Fusarium species was notably less than that of T. harzianum. In contrast, in the dual culture assay, the bioagent fungal filtrate exhibited inhibitory effects on the growth of all pathogens at 25% concentration. The highest inhibition rate (85%) was shown by T. harzianum against F. incarnatum. The percent of inhibition caused by P. ostreatus was substantially lower than that caused by T. harzianum, which reached 35% in F. incarnatum followed by other pathogens. The volatile compounds of T. harzianum led to a high percentage of inhibition of all the three Fusarium species, while the highest percentage of inhibition due to the compounds of P. ostreatus was observed only for F. solani AJA1 (41.5%). From these results, we concluded that despite the diverse inhibitory effects of both bioagent fungi against Fusarium species, they exhibited successful antagonistic activity and the ability to compete against these species.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89926307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Initial estimates in 2020 found children were less likely to become infected with SARS-CoV-2 and more likely to be asymptomatic or display mild COVID-19 symptoms. Our early understanding of COVID-19 transmission and disease in children led to a range of public health measures including school closures that have indirectly impacted child health and wellbeing. The emergence of variants of concern (particularly delta and omicron) have raised new issues about transmissibility in children, as preliminary data suggests children may be at increased risk of infection especially if unvaccinated. Global national prevalence data shows SARS-CoV-2 infection in children and adolescents is rising due to COVID-19 vaccination among adults and increased circulation of delta and omicron variants. To mitigate this, childhood immunisation programs are being implemented globally to prevent direct and indirect consequences of COVID-19 including severe complications (e.g. MIS-C), debilitating long-COVID symptoms, and the indirect impacts of prolonged community and school closures on childhood education, social and behavioural development and mental health.

The role of adaptive immune system during HBV infection has been well studied. However, the innate immune system's responses against HBV during the early stage of infection largely remain unclear. In this study, we found that HBV genomic DNA or Salmon Sperm DNA (SSD) was able to induce the innate immune response in the macrophages cell line RAW264.7 but not the hepatocyte cell line, HepG2, indicating that hepatocytes may lack of a functional DNA-sensing pathway and hence are unable to respond to the presence of foreign DNA in the cytosol with type 1 IFN response. Thus, we hypothesized that non-parenchymal cells like the Antigen Presenting Cells (APC) might be crucial in triggering the initial immune response to suppress the virus replication and link the innate and adaptive responses. Using bone marrow-derived DCs (BMDC) as a model, this study demonstrated that HBV genomic DNA is able to induce cytokines like TNF-alpha, IL-6, and IL-12p40 secretion. We also examined the activation and maturation of BMDCs when exposed to the HBV genomic DNA intracellularly and extracellularly. A significant shift of CD86+ and CD40+ cell populations was observed during extracellular exposure of BMDC to Poly I:C and HBV genomic DNA, indicating that TLRs may be vital in the uptake of the extracellular viral DNA to activate the BMDCs. Moreover, transfection of intracellular nucleic acid stimuli, including HBV genomic DNA as well induced BMDCs maturation. Our findings highlight the critical function of DCs in antiviral response as a potential connection between the innate and adaptive immune systems during HBV pathogenesis. Nevertheless, further study is required to determine the role of cytosol DNA sensing pathway in DCs during HBV infection.","PeriodicalId":8566,"journal":{"name":"Asia-pacific Journal of Molecular Biology and Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74800675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
