A shared mechanism for Bacteroidota protein transport and gliding motility

Nature Communications
Bacteria of the phylum Bacteroidota are major human commensals and pathogens in addition to being abundant members of the wider biosphere. Bacteroidota move by gliding and they export proteins using the Type 9 Secretion System (T9SS).

Successional action of Bacteroidota and Firmicutes in decomposing straw polymers in a paddy soil

Environmental Microbiome, 2023
Background Decomposition of plant biomass is vital for carbon cycling in terrestrial ecosystems. In waterlogged soils including paddy fields and natural wetlands, plant biomass degradation generates the largest natural source of global methane emission ...

Study of Human Antimicrobial Peptides Active Against Some Bacteroidota Species of the Oral Cavity

Antibiotics
The increasing problem of antibiotic resistance is a critical global health issue, necessitating the development of alternative therapeutic strategies to manage infections effectively. Among the promising solutions are human antimicrobial peptides (AMPs),

Gut microbiota-dependent protection by Lactobacillus reuteri against renal injury in brain-dead rats [PDF]

Scientific Reports
Donation-after-brain-death (DBD) serves as a major source of kidney transplant donors, and brain death (BD) induces systemic inflammation and gut barrier disruption, leading to renal injury and compromised organ quality.

Carbon-Source Effects on Growth and Secondary Metabolism in the Marine Bacteroidota Tenacibaculum mesophilum and Fulvivirga kasyanovii

Marine Drugs
Marine Bacteroidota are recognized bacterial producers of bioactive metabolites, yet their biosynthetic potential remains cryptic under standard laboratory conditions. Here, we developed chemically defined media for Fulvivirga kasyanovii 48LL (Cytophagia)

Characterization of Maribacter polysaccharolyticus sp. nov., Maribacter huludaoensis sp. nov., and Maribacter zhoushanensis sp. nov. and illumination of the distinct adaptative strategies of the genus Maribacter

Frontiers in Marine Science, 2023
Polysaccharides are complex carbohydrates and are abundant in the marine environment. Microbes degrade and utilize them using Carbohydrate-active enzymes (CAZymes), which mediate polysaccharides into the marine carbon cycle.

Bacteroidota inhibit microglia clearance of amyloid-beta and promote plaque deposition in Alzheimer’s disease mouse models

Nature Communications
The gut microbiota and microglia play critical roles in Alzheimer’s disease (AD), and elevated Bacteroides is correlated with cerebrospinal fluid amyloid-β (Aβ) and tau levels in AD.

The Histidine Biosynthetic Genes in the Superphylum Bacteroidota-Rhodothermota-Balneolota-Chlorobiota: Insights into the Evolution of Gene Structure and Organization [PDF]

Microorganisms, 2021
One of the most studied metabolic routes is the biosynthesis of histidine, especially in enterobacteria where a single compact operon composed of eight adjacent genes encodes the complete set of biosynthetic enzymes. It is still not clear how his genes were organized in the genome of the last universal common ancestor community.

The basis of antigenic operon fragmentation in Bacteroidota and commensalism

, 2023
Abstract The causes for variability of pro-inflammatory surface antigens that affect gut commensal/opportunistic dualism within the phylum Bacteroidota remain unclear (1, 2). Using the classical lipopolysaccharide/O-antigen ‘ rfb operon’ in

Physiological and Genomic Characterization of Two Novel Bacteroidota Strains Asinibacterium spp. OR43 and OR53 [PDF]

Bacteria, 2022
Asinibacterium spp. (Family Chitinophagaceae, Phylum Bacteroidota) are abundant in environments contaminated with heavy metals. We characterized the physiology and genome of two Asinibacterium species to elucidate their ability to survive and grow at ambient conditions in the uranium-contaminated environments.
