Brevibacillus thermoruber strain 423 is a Gram-positive, spore-forming, aerobic, and thermophilic bacterium that produces mannogalactoglucan exopolysaccharide (EPS). We report the draft genome sequence of B. thermoruber 423, which will accelerate research on the cellular organization of thermophilic bacteria, as well as the rational design and optimization of EPS production.

Fat waste discarded from butcheries was used as a cosubstrate in the anaerobic codigestion of sewage sludge (SS). The process was evaluated under mesophilic and thermophilic conditions. The codigestion was successfully attained despite some inhibitory stages initially present that had their origin in the accumulation of volatile fatty acids (VFA) and adsorption of long-chain fatty acids (LCFA)....

A sensitive PCR assay that detects the thermophilic campylobacters C. jejuni, C. coli, C. lari, and C. upsaliensis is reported. Furthermore, by digestion of the PCR products with two restriction enzymes, species differentiation was demonstrated. Thus, the present method has the potential to be used for both detection and identification of thermophilic Campylobacter species.

A thermophilic strain (D2) identified as a Bacillus sp. was isolated from an aerobic digestor of swine waste after several months of operation at 55 degrees C. Aerobic thermophilic batch treatment of swine waste inoculated with strain D2 was studied in a 4-liter fixed-bed reactor. Stabilization of the waste was achieved in less than 30 h when the original chemical oxygen demand (COD) was betwee...

BACKGROUND In this research, the feasibility of, and population dynamics in, one-step anaerobic sequencing batch reactor systems treating the fine sieved fraction (FSF) from raw municipal wastewater was studied under thermophilic (55 °C) and mesophilic (35 °C) conditions. FSF was sequestered from raw municipal wastewater, in the Netherlands, using a rotating belt filter (mesh size 350 micron). ...

The most common technology for the recovery of energy and valuable materials from sewage sludge is anaerobic digestion (AD). Ensuring thermophilic conditions during AD has been proven to cause process intensification an improvement in its final outcomes. Nonetheless, search underway other methods bolster effectiveness aerobic granular (AGS), which characterized by a compact complex structure. A...
