Unusual production of glutathione in Actinobacteria [PDF]

Archives of Microbiology, 2008
Most Actinobacteria produce mycothiol as the major thiol. In addition to mycothiol Rhodococcus AD45 generates a substantial level of glutathione possibly using genes acquired in a lateral transfer. Instead of mycothiol, Rubrobacter radiotolerans and Rubrobacter xylanophilus produce glutathione, whose synthesis appears to involve enzymes substantially ...

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Molecular Characterization of Plasmids Harbored by Actinomycetes Isolated From the Great Salt Plains of Oklahoma Using PFGE and Next Generation Whole Genome Sequencing

Frontiers in Microbiology, 2018
One of the unique features of actinomycetes, especially the genus Streptomyces, is the presence of linear plasmids. These range in size from 12 to 600 kb, and are often termed mega-plasmids.

Structural Analysis of Polarizing Indels Argues the Root of the Tree of Life is Near the Chloroflexi [PDF]

, 2009
Determining which branches of the tree of life have derived features narrows down the possible location of the root. Currently the polarization of indels done by Lake _et al_.^1-5^ and the polarizing transitions of Cavalier-Smith^6^ arrive at ...

Metagenomic and culture‐based insights into host and plasmid contexts of high‐risk ARGs in poultry farm environments

iMetaOmics, EarlyView.
Shotgun metagenomics and culture‐based isolate genomics revealed position‐associated high‐risk antibiotic resistance genes (ARGs) signals across poultry manure piles and surrounding soils. Culture‐confirmed Enterobacteriaceae and IncHI2A‐related blaNDM‐5 plasmid backgrounds further highlight priority host‐ARG‐plasmid contexts for farm antimicrobial ...

Nutritional and environmental determinants of maturation and disruption of the early life gut microbiome: A narrative review

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract The first 1000 days of life represent a critical window for gut microbiome assembly, with lifelong implications for child growth, immune development, and disease risk. This review synthesizes evidence on maternal, perinatal, and especially nutritional factors that influence early‐life intestinal colonization and highlights the consequences of ...

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fractions and their distribution, molecular characterization, enzyme activity ...
