The beneficial effects of terrestrial probiotics on shrimp may be affected due to environmental differences between the cultivated species and the source of the probiotics. To ensure maximum effects on the host, it is essential to use probionts derived from the host or the environment of the cultured organism. Consequently, the objective of this study was to isolate and characterize potential probionts from brackishwater by enriching the water with organic sources containing a high ratio of carbon to nitrogen (C:N). Six 10-li containers were filled with brackishwater from an estuary for a mesocosm experiment. To stimulate bacterial growth, water was enriched with either molasses or brown sugar at a C:N ratio of 15. After twenty days, all heterotrophic bacteria in the enriched water were enumerated. The in vitro antagonistic activities of distinct bacterial colonies against Vibrio harveyi, a crustacean pathogen, were evaluated on fresh Nutrient Agar plates containing 1% sodium chloride. There were 10 bacterial isolates with in vitro antibacterial activity. These bacterial isolates are categorized as belonging to the putative genera Acinetobacter, Pseudomonas, Sphingobium, and Rheinheimera. The implications of this study suggest that enriching brackishwater with organic carbon sources at high C:N ratios may increase the likelihood of isolating and developing potential probionts for shrimp aquaculture.","PeriodicalId":16348,"journal":{"name":"Journal of microbiology, biotechnology and food sciences","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47687122","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}

Plant-microbe interaction array depicts both mutualism and pathogenesis. This dual nature of microbes depends on their surrounding abiotic and biotic factors. Endophytes are plant symbionts, beneficial for plant health. Some microbes are harmful for plants and they also live inside the plants, are called pathogens. The interactions that exist between the endophytic communities have hardly been investigated. The microbes associated with the plants act mostly according to environmental factors. These factors have the ability to alter the nature of microbes from endophytes to pathogens and vice-versa. Thus, by modulating such environmental factors, these microbes can be designed to produce important secondary metabolites or desired products, either within the plants or under laboratory conditions. The plant-microbe interactions have immense research orientation in the near future. The international demand for medicinal plant-based resources has increased due to their augmented exploitation for research and development. Studies of such plants species having parallel phytochemical constituents or microbes producing similar constituents could be an effective way of circumventing this global demand gap. The present review gives a detailed description of the dual behavior that exists in plant endophytes. In addition, it details a state of coherence in their vivid mannerisms and various applications of microbes in different aspects, environmental safety, agriculture, and pollution control.","PeriodicalId":16348,"journal":{"name":"Journal of microbiology, biotechnology and food sciences","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44798119","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}

The survival of microbial communities and entire aquatic ecosystems depends directly on their ability to adapt to this type of pollution. One of the most common micropollutants found in water bodies, especially in the vicinity of large cities, is caffeine. This stimulant directly affects living organisms and can cause changes in the species composition of microbial communities. However, the best way to decontaminate caffeine from the environment may be through the use of microorganisms. Therefore, in this study, the effect of caffeine on selected species of cyanobacteria and algae was investigated. The following strains of cyanobacteria: Geitlerinema cf. acuminatum (CCALA 141), Chlorogloeopsis fritschii (CCALA 039), Chlorogloeopsis fritschii (CCALA 1005), and Synechococcus granulates (CCALA 187) and a eukaryotic photosynthetic flagellate Euglena gracilis (strain Z) were selected. Probit analysis determined the minimum inhibitory concentration (MIC) of caffeine for each studied species. Also, the inhibitory effect of caffeine on each tested strain was monitored in vivo. Next, the strains were microscopically observed, and the potential change in their morphology under the caffeine treatment was recorded. The reproduction rate of all species in the study were moderately inhibited by caffeine, but during the cultivation, they were able to grow in comparison with the control sets. The most sensitive species was Geitlerinema cf. acuminatum (CCALA 141). The study also showed a significant effect of caffeine on morphology changes in the strains under investigation. Caffeine at low concentrations also showed a stimulating effect on the growth of the studied species. This may lead to their improved competence potential within microbial communities in the aquatic biotopes.","PeriodicalId":16348,"journal":{"name":"Journal of microbiology, biotechnology and food sciences","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47791231","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}

The aim of this research was to test the effect of fifteen EOs extracted from plants of the Lamiaceae family on five strains of Cladosporium cladosporioides. Cladosporium cladosporioides is frequently found on fruit and may be involved in fruit spoilage. The strains used in the study were isolated directly from lesions on berries. The growth of the fungi on the fruit was the reason for its rejection from sale. The antifungal activity of EOs against Cladosporium cladosporioides strains was determined by the microatmospheric method (625 μl EO/L air) during 14 days of cultivation. Thirteen EOs: thyme and red thyme (from Thymus vulgaris L.), mitcham mint (Mentha x piperita L. var. Mitcham), peppermint (Mentha x piperita L.), savory (Satureja hortensis L.), sage (Salvia officinalis L.), spearmint (Mentha spicata L. var. crispa), lavender (Lavandula angustifolia Mill.), marjoram (Origanum majorana L.), bergamot-mint (Mentha citrata Erh.), wild thyme (Thymus serpyllum  L.), hyssop (Hyssopus officinalis L.), and oregano (Origanum vulgare L.) were shown to inhibit growth of all strains to 100%. Basil (Ocinum basilicum L.) and rosemary (Rosmarinus officinalis L.) EOs did not have a 100% inhibitory effect on all strains throughout the cultivation period. Subsequently, minimum inhibitory concentrations (MIDs) were determined using the microatmospheric method. LD90 and LD50 values were estimated by probit analysis. Based on the MID, LD90, and LD50 results, the essential oils can be divided into three groups. The first group (most effective): thyme, red thyme, spearmint, wild thyme, and oregano EO; the second group: peppermint, lavender, mitcham mint and savory EO; the third group: sage, marjoram, bergamot-mint and hyssop EO. The most effective EOs can be used to suppress the growth of Cladosporium cladosporioides in the vapour phase.","PeriodicalId":16348,"journal":{"name":"Journal of microbiology, biotechnology and food sciences","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49283314","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}

Therefore, it has several applications in the food and pharmaceutical industries. However, the structure of chitosan may limit its solubility and bioavailability. The current study aimed to improve the physicochemical properties of chitosan by combining it with vitamin E nanoemulsion (CH-NE-vitE). The structural, thermal stability, and physical differences between chitosan and its new derivative were analyzed using the scanning electron microscope (SEM), Fourier transform infrared (FTIR) spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, and differential scanning calorimetry (DSC). Furthermore, the antimicrobial activities of CH-NE-vitE against Staphylococcus aureus, Candida krusei and Enterobacter hormaechei were examined using disc and well diffusion methods in addition to the determination of the minimum inhibitory concentration (MIC). The morphology changes in the treated microbes were visualized using the SEM. The characterization of CH-NE-vitE exhibited noticeable changes in the chitosan physical properties and chemical structure including increased solubility, interaction rates, and stability. The new derivative has inhibited the growth of both S. aureus, and C. krusei while promoting the growth of E. hormaechei. The minimum inhibitory concentrations against the S. aureus, and C. krusei were 1.563 mg/mL and 3.125 mg/mL, respectively. The produced CH-NE-vitE can be used in drug delivery, dermal products, and food packaging.","PeriodicalId":16348,"journal":{"name":"Journal of microbiology, biotechnology and food sciences","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48118824","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}

Lactose intolerance (LI) is one such situation, where individual show lactose maldigestion after the consumption of dairy products. It is necessary to overcome such a condition by employing indigenous beneficial bacteria or their products. Therefore, in this study we have isolated and characterized LAB from fermented milk samples, from remote villages of districts of south India. Traditionally fermented milk samples (68) were collected, cultivated on MRS medium, identified by biochemical and carbohydrate metabolic activity and correlated with Bergey's manual of systematic bacteriology. When matched with other LAB, Lactiplantibacillus isolates were able to reduced pH of medium significantly and reached pH of 4.6 in 48 hours. On MRS agar, 450 different bacterial isolates were isolated, recognized as presumptive LAB and classified up to the level of genera as Lactiplantibacillus (285), Lactococcus (70), Pediococcus (19), Streptococcus (20), and Enterococcus (16). Later, β-galactosidase screening was carried out using MRS/X-gal agar medium. Out of 450 LAB isolates only Lactiplantibacillus isolates were potential β-galactosidase producers. GRAS organisms such as LAB are multifaceted diverse group of bacteria localized in varieties of fermented foods/in the intestine and recognized as probiotics. Distinct contribution of LAB in health care and disorder management made this organism as a choice for alternate therapy; hence functionality of LAB can be promoted for LI management.","PeriodicalId":16348,"journal":{"name":"Journal of microbiology, biotechnology and food sciences","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44192013","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}
