AI Article Synopsis
- The study focused on improving hydrolysis acidification (HA) by using a halophilic bacterial consortium that was enriched in a 5% saline environment.
- The bacterial consortium effectively decolorized metanil yellow G dye at various salinity levels (1%-15%) and dye concentrations (100-400 mg/L) while demonstrating enhanced performance in COD removal and increasing the BOD/COD ratio after bioaugmentation.
- Sequencing analysis revealed significant shifts in bacterial communities and diversity post-bioaugmentation, with Marinobacterium becoming the dominant genus and playing a crucial role in the decolorization of azo dyes.
Article Abstract
The aim of this work was to study the bioaugmentation of hydrolysis acidification (HA) by a halophilic bacterial consortium. A bacterial consortium was enriched at 5% salinity, and it decolorized metanil yellow G (MYG) at salinities of 1%-15% and dye concentrations of 100-400 mg/L under static conditions. A HA system was constructed to assess the effectiveness of bioaugmentation by the halophilic bacterial consortium. The HA system showed obviously better performance for decolorization and COD removal and presented higher the 5-day biological oxygen demand (BOD)/COD (B/C) ratio after bioaugmentation. MiSeq sequencing results indicated that the bacterial communities remarkably shifted and that the bacterial diversity was increased after bioaugmentation. Marinobacterium invaded the native microbe community and became the dominant bacterial genus in the bioaugmented HA, and it played a key role in azo dye decolorization. Therefore, bioaugmentation with a halophilic bacterial consortium improved the HA system for decolorization of azo compounds.

Background: The GI tract is home to approximately 70% of the body's immune cells, >100 million enteric neurons, and ∼40 trillion bacteria. This co-localization of myriad immune, neural and bacterial cells creates complex interactions that regulate almost every tissue in the body, including the brain. Importantly, peripheral and GI inflammation occur in neurodegenerative diseases such as Parkinson's disease (PD) and Alzheimer (AD) contributing to gut brain axis.

Donor-derived fecal micrrasobiota treatments are efficacious in preventing recurrent Clostridioides difficile infection (rCDI), but they have inherently variable quality attributes, are difficult to scale and harbor the risk of pathogen transfer. In contrast, VE303 is a defined consortium of eight purified, clonal bacterial strains developed for prevention of rCDI. In the phase 2 CONSORTIUM study, high-dose VE303 was well tolerated and reduced the odds of rCDI by more than 80% compared to placebo.

Mobile genetic elements are key to the global emergence of antibiotic resistance. We successfully reconstructed the complete bacterial genome and plasmid assemblies of isolates sharing the same carbapenemase gene to understand evolution over time in six confined hospital drains over five years. From 82 isolates we identified 14 unique strains from 10 species with 113 carrying plasmids across 16 distinct replicon types.

Evidence suggests that the gut microbiome may play a role in multiple sclerosis (MS). However, the majority of the studies have focused on gut bacterial communities; none have examined the fungal microbiota (mycobiota) in persons with pediatric-onset multiple sclerosis (POMS). We examined the gut mycobiota in persons with and without POMS through a cross-sectional examination of the gut mycobiota from 46 participants' stool samples (three groups: 18 POMS, 13 acquired monophasic demyelinating syndromes [monoADS], and 15 unaffected controls).

Two marine-derived bacteria, Bacillus paralicheniformis (HR-1) and Bacillus haynesii (HR-5), were isolated from sediments and identified using 16S ribosomal RNA gene amplification and sequencing as well as biochemical analysis. The development of a bacterial consortium (HR-1 & HR-5) from these two bacteria was used to increase the production of the protease enzyme under various conditions, including fermentation media, carbon and nitrogen sources (1% w/v), different pH levels, incubation time, and the obtained enzyme, were detected using SDS-PAGE followed by purification. Bacterial consortium HR-1 & HR-5 exhibited maximum protease production (330.
