Summary: Three Gram-stain-positive bacterial strains were isolated from honeybee gut and characterized using a polyphasic taxonomic approach. Genetic analysis revealed that two of the strains were closely related to known Apilactobacillus species but had lower sequence similarities, leading to the proposal of two new species within the genus. The findings highlight the diversity of bacterial strains in the honeybee gut.

Summary: In the world of highly processed foods, there is growing attention to the nutrient composition and safety of consumed food products. Foods fortified with probiotic bacteria have positive effects on human health, and soy foods are an excellent choice for delivering probiotics and prebiotics. Using probiotics and prebiotics together in a product, known as synbiotics, shows great potential in meeting consumer needs.

Summary: In this study, a novel and simple approach was developed to improve the cultivability of natural microorganisms without the need for sophisticated instrumentation. The method involved gradient centrifugation combined with serial dilution to enhance the recovery of taxa from environmental samples. This approach allowed for the isolation of a higher number of genera and species compared to traditional serial dilution alone, offering access to untapped microbial diversity.

Summary: This study conducted a comparative analysis of three different landfill leachate samples and revealed a diverse range of bacteria and archaea, some of which may be potential novel taxa. The research also highlighted the high stress levels and presence of toxic wastes in leachate, with archaea playing a significant role in leachate ecology. Further in-depth studies on leachate samples are necessary to understand nutrient cycling and develop effective treatment technologies.

Summary: We compared and analyzed the population of oligotrophs and copiotrophs in Lonar Lake, India. Through isolating strains from sediment and using different nutrient-rich and oligotrophic media, we found that copiotrophic microorganisms dominated the lake. Changes in medium composition and nutrient level affected the selection of organisms from the same sample.

Summary: This study characterized the microbial community at different depths of a landfill to assess their roles as methane sinks. The results showed anaerobic degradation of organic matter in the bottom soil and active aerobic denitrification in the top soil. The top soil had a higher abundance of aerobic methanotrophs, while the bottom soil had a dominance of anaerobic methanogens. The findings provide a better understanding of the relationship between methanotrophs and their environment in landfills.

Summary: Methanogenic archaea are diverse prokaryotes capable of producing methane as their main product. With advancements in technology, taxonomy criteria for these archaea need to be revised. The previously recommended minimum standards for phenotypic characterization of pure cultures are mostly maintained. Obtaining whole genome sequences for type strains and comparing them with close relatives using genomic indices is now mandatory. Additionally, culture purity is not essential and alternative methods like single-cell or metagenomics can be used for taxonomic description.
