Aerobic ammonia oxidation is crucial to the nitrogen cycle and is only known to be performed by a small number of bacterial lineages [ammonia-oxidizing bacteria (AOB)] and a single lineage of archaea belonging to the …
Read PDF<i>Bifidobacterium breve</i> is recognized as a probiotic with immune-enhancing properties. However, our previous studies revealed that this species is present at a higher relative abundance in the gut microbiome of infants with atopic dermatitis (AD). …
Read PDFActinobacteria associated with medicinal plants are recognized as prolific sources of novel bioactive compounds. Kratom (<i>Mitragyna speciosa</i>) leaves have been reported to contain a diverse array of secondary metabolites with pharmacological activities, including antibacterial, antioxidant, …
Read PDF<h4>Background</h4>Microbial culture collections play a key role in taxonomy by studying the diversity of their strains and providing well-characterized biological material to the scientific community for fundamental and applied research. These microbial resource centers thus …
Read PDF<i>Haemophilus</i> and <i>Aggregatibacter</i> are two of the most common bacterial genera in the human oral cavity, encompassing both commensals and pathogens of substantial ecological and medical significance. In this study, we conducted a metapangenomic analysis …
Read PDFFour Gram-stain-positive, aerobic, non-motile and non-spore-forming actinobacterial strains (CPCC 206391<sup>T</sup>, CPCC 206453<sup>T</sup>, CPCC 206435<sup>T</sup> and CPCC 206450<sup>T</sup>) were isolated from soil samples collected from Tibet Autonomous Region, China. The 16S rRNA gene sequences of these …
Read PDF<h4>Background</h4>The Iceman mummy, a 5300-year-old natural alpine glacier mummy, provides a unique opportunity to study ancient microbial ecosystems. However, disentangling the mummy's endogenous microbiome from modern environmental contaminants introduced during three decades of conservation remains …
Read PDFSeaweeds are known for their rich bioactive compounds with potential applications in biotechnological and industrial fields. However, seaweed associated bacteria are least explored for bioactive and other functional capabilities. A study aimed to bio-prospect seaweed …
Read PDFBacterioplankton of the SAR11 clade are the most abundant marine microorganisms and consist of numerous subclades spanning order-level divergence (<i>Pelagibacterales</i>). The assignment of the earliest diverging subclade V (a.k.a. HIMB59) to the <i>Pelagibacterales</i> is highly …
Read PDFA thermophilic, yellow-pigmented bacterial strain, designated LT1-2-5<sup>T</sup>, was isolated from litter in the Cisolok Geyser, West Java, Indonesia. This strain is Gram-stain-negative, aerobic and non-sporulating, with rod-shaped cells and short filaments. Phylogenetic analyses based on …
Read PDFA microbial community study using a culture-dependent method was conducted on dehydrated sludge collected from a steel factory's wastewater treatment plant. One isolate, designated QWL-01<sup>T</sup>, was a strictly anaerobic, Gram-stain-negative, non-motile, non-spore-forming bacterium with coccoid …
Read PDFPsychoactive mushrooms in the genus <i>Psilocybe</i> have immense cultural value and have been used for centuries in Mesoamerica. Despite the recent surge of interest in these mushrooms due to the psychotherapeutic potential of their natural …
Read PDFMarine algae underpin entire ocean ecosystems. Yet algae in culture poorly represent their large environmental diversity, and we have a limited understanding of their convoluted evolution by endosymbiosis. Here, we perform a phylogeny-guided plastid genome-resolved …
Read PDFPlant-microbiome research plays a pivotal role in understanding the relationships between plants and their associated microbial communities, with implications for agriculture and ecosystem dynamics. Metabarcoding analysis on variable regions of the 16S ribosomal RNA (rRNA) …
Read PDFShotgun metagenomics has become a pivotal technology in microbiome research, enabling in-depth analysis of microbial communities at both the high-resolution taxonomic and functional levels. This approach provides valuable insights of microbial diversity, interactions, and their …
Read PDF<h4>Introduction</h4>Nus-dependent Mexican <i>Escherichia coli</i> phages (mEp) were previously isolated from clinical samples of human feces. Approximately 50% corresponded to non-lambdoid temperate phages integrating a single immunity group, namely immunity I (mEp<sub>immI</sub>), and these were as …
Read PDFLong-term use of chemical fungicides to control plant diseases caused by fungi and oomycetes has led to pathogen resistance and negative impacts on public health and environment. There is a global search for eco-friendly methods …
Read PDFBenthic cyanobacterial mats in flowing waters are complex communities typically composed of taxa from the orders Coleofasciculales and Oscillatoriales, many of which have unresolved taxonomic positions and poorly characterized toxic potential. We collected field mats …
Read PDFThe abundant and metabolically versatile aquatic bacterial order, <i>Rhodobacterales</i>, influences marine biogeochemical cycles. We assessed <i>Rhodobacterales</i> metagenome-assembled genome (MAG) abundance, estimated growth rates, and potential and expressed functions in the Chesapeake and Delaware Bays, two …
Read PDFA novel, strictly anaerobic, slightly alkaliphilic, halotolerant, peptide- and amino acid-utilizing bacterial strain, SD1<sup>T</sup>, was isolated from a hypersaline lake in Western Australia. The strain stained Gram-negative and was a motile, spore-forming rod. The strain …
