Bacillus sp. is well known for its functional capabilities such as solubilizing phosphorus (P) and potassium (K), fixing nitrogen (N2). These bacteria can form endospores under stressed conditions, allowing long-term survival application in biotechnological fields. This study aims to isolate capable of forming evaluates their viability on different carriers, specifically biochar oil spill dispersant (OSD), enhance biodegradation contaminated environments. Soil samples from the bamboo rhizosphere were heat-shocked endospore-forming strains, with identified pseudomycoides RAY21 through 16S rRNA sequencing. strain exhibited Gram-positive characteristics, formed endospores, demonstrated potential various media Pikovskaya, Alexandrov, N-Free Mannitol. The physiological characterization indicated optimal growth a pH range 6-8, salinity up 3.5%, thermophilic properties. Endospores B. subtilis CYA27 tested OSD carriers. results showed that adhered better biochar, but was more stable over time. Notably, degraded 23.43% total petroleum hydrocarbons (TPH), outperforming (21.62%). In conclusion, demonstrates using an effective carrier bioremediation, particularly degrading hydrocarbons. Future research should focus optimizing materials exploring field-scale applications enhanced environmental cleanup.

Anaerobic digestion (AD) is a biological process that occurs in the limited presence of oxygen. This involves various difficulties during operation, such as acidification and increased concentration volatile fatty acids, which can inhibit methane production. Therefore, this work, impact biochar on co-digestion untreated sludge residual biomass under mesophilic conditions was studied. For production biochar, gasification used at different temperatures: 759 °C (BL), 798 (BM), 888 (BH). added concentrations 0 g/L, 3.33 6.67 g/L beginning process. The results showed with BH PBM by 18% compared to control sample reduced chemical oxygen demand (COD) 88%. In addition, there reduction acids (VFA) 42.75%. Furthermore, FTIR analysis demonstrated has appropriate functional groups for These data suggest good interaction mixture municipal waste, indicating improve anaerobic waste.

Microbially induced calcium carbonate precipitation (MICP) provides a novel approach for use in addressing the instabilities of borehole walls comprising broken formations, but highly alkaline environments drilling fluids are unfavorable microbial growth. Therefore, this study investigated alkali-resistant domestication Bacillus pasteurii commonly used MICP. Using gradient domestication, B. was domesticated under different pH conditions (pH 8.0, 9.0, 10.0, and 11.0) sodium carboxymethyl cellulose solid-free fluids. Its growth patterns variations urease activity were analyzed to assess effectiveness domestication. The Gompertz logistic models fit conditions, kinetic constructed based on mean square error, Akaike information criterion, coefficient determination. bacterial concentration enhanced after model accurately described at 11.0, whereas pattern 9.0. This scientific evidence theoretical basis maintaining stabilities formations.
