AI Article Synopsis
- - Japanese goats were studied to see how a diet with 50% Timothy grass and 50% concentrate, along with increasing levels of bromochloromethane (BCM), affected their rumen microbial population and fermentation processes.
- - Researchers found that as BCM levels increased, certain microbial species, particularly hydrogen-consuming Prevotella and Selenomonas, thrived, leading to a shift in fermentation towards propionate production instead of methane.
- - Metagenomic analyses showed that reductive acetogenic species were not significantly involved in the rumen of goats treated with BCM, indicating a distinct microbial adaptation to the changes caused by the compound.
Article Abstract
Japanese goats fed a diet of 50% Timothy grass and 50% concentrate with increasing levels of the anti-methanogenic compound, bromochloromethane (BCM) were investigated with respect to the microbial population and functional shifts in the rumen. Microbial ecology methods identified species that exhibited positive and negative responses to the increasing levels of BCM. The methane-inhibited rumen appeared to adapt to the higher H2 levels by shifting fermentation to propionate which was mediated by an increase in the population of H2-consuming Prevotella and Selenomonas spp. Metagenomic analysis of propionate production pathways was dominated by genomic content from these species. Reductive acetogenic marker gene libraries and metagenomics analysis indicate that reductive acetogenic species do not play a major role in the BCM treated rumen.

A suitable solvent for adsorption of poorly water-soluble substances onto silica gel in a ready biodegradability test.

When a test substance is poorly water-soluble, it can be adsorbed onto silica gel to facilitate dispersibility in a ready biodegradability test. To uniformly adsorb the test substance onto silica gel, the substance is dissolved in a solvent and then mixed with the silica gel. It is desirable for the solvent to completely evaporate afterward.

We investigated whether various modified cyclodextrins (CDs) and emulsifiers could be applied as dispersing agents in ready biodegradability tests of poorly water-soluble substances. Trimethylated α-, β-, and γ-CDs and partially methylated β-CD were not biodegraded in the test period but accelerated the biodegradation of octabenzone and anthraquinone. The process by which trimethylated α-, β-, and γ-CDs enhance the biodegradation of test substances has been partially uncovered.

Plants are colonized by a vast array of microorganisms that outstrip plant cell densities and genes, thus referred to as plant's second genome or extended genome. The microbial communities exert a significant influence on the vigor, growth, development and productivity of plants by supporting nutrient acquisition, organic matter decomposition and tolerance against biotic and abiotic stresses such as heat, high salt, drought and disease, by regulating plant defense responses. The rhizosphere is a complex micro-ecological zone in the direct vicinity of plant roots and is considered a hotspot of microbial diversity.

Background: Improved diagnostic testing (DT) of infections may optimize outcomes for solid organ transplant recipients (SOTR), but a comprehensive analysis is lacking.
Methods: We conducted a systematic literature review across multiple databases, including EMBASE and MEDLINE(R), of studies published between 1 January 2012-11 June 2022, to examine the evidence behind DT in SOTR. Eligibility criteria included the use of conventional diagnostic methods (culture, biomarkers, directed-polymerase chain reaction [PCR]) or advanced molecular diagnostics (broad-range PCR, metagenomics) to diagnose infections in hospitalized SOTR.

The pathophysiological mechanism of abdominal aortic aneurysm (AAA) remains unclear. We previously reported that levels were reduced in the feces of patients with AAA by 16S ribosomal ribonucleic acid (RNA) gene sequencing. In this study, we increased the number of cases and conducted metagenomic analyses to examine bacterial genes associated with the pathophysiology of AAA.
