Upper mesophilic temperature acclimation of halophilic, hydrogen-producing bacteria from salt fields was investigated in this study, along with the changes microbial abundance during an-aerobic digestion (AD) process. Genomic approaches such as PCR-denaturing gradient gel elec-trophoresis (DGGE) and next-generation sequencing (NGS) were performed to profile mi-crobial communities. During AD, there a significant Halanaerobacter lacunarum at 48°C followed by increase hydrogen yield, signifying potential contribution halophile production. A decrease dominance H. Halan-aerobium fermentans 42°C, likely due an other bacterial species, noted but their significantly increased temperatures 45°C 48°C. This investigation provides valuable insights highlighting Halanaerobium sp. halo-philic adapt under upper conditions synthesizing hy-drogen. The findings present study also underscore importance optimizing temper-ature pH maximize yield high-salt anaerobic digestion.

Anaerobic digestion (AD) is a well-established technology for the sustainable conversion of agricultural organic by-products and waste into bioenergy. Temperature crucial optimizing methane production through inocula preservation reactor start-up in AD. The induced by temperature has rarely been assessed from an engineering perspective. There also limited exploration influence high-to-moderate transition on initiation This study employed continuous mesophilic AD reactors with potential applications to conduct revival tests. These tests evaluated activity sludge stored at different temperatures investigated impact high-temperature Additionally, we elucidated correlation between these assessments microbial diversity as well composition. results indicated that bacterial was higher inoculum 35 °C compared 15 °C, ensuring stable operation richness bacteria archaea remained during high temperatures. conducive enhancing methanogenic initiated 55 °C. continuously operated system showed significant differences composition its inoculum. Increased abundance Coriobacteriaceae Prevotellaceae led propionate butyrate accumulation, respectively, reducing operational capacity. Methanogenic were less diverse low-temperature preserved medium temperature. Streptococcaceae temperarure could promote stability. Hydrogenotrophic methanogens had competitive advantage due their prior exposure initiation, possibly influenced Thermotogaceae.

Synthetic detergent contains linear alkyl sulfonate (LAS) that presents a greater environmental risk compared to other contaminants. There has been an interest in replacing synthetic with more biodegradable made from mixture of sodium and potassium fatty acid. The present study conducted field experiment by the usage soap (a combination acid) two household areas evaluate divergent effect on microbiome activated sludge process for sewage treatment. Results indicated use increased abundance acid-consuming bacteria nitrogen-fixation bacteria. Additionally, enables strains be proactive degrading organic matter, LAS, anionic, nonionic surfactants. Consequently, detergents WWTP service can positively influence microbial dynamics, improving overall efficiency wastewater treatment process.
