A Novel Estrone Degradation Gene Cluster and Catabolic Mechanism in Microbacterium oxydans ML-6

Lei Miao et al.

Summary: The study examined the degradation of estrone (E1) by Microbacterium oxydans ML-6, isolated from estrogen-contaminated soil, and proposed a complete catabolic pathway for E1. A novel gene cluster (moc) associated with E1 catabolism was predicted, and the 3-hydroxybenzoate 4-monooxygenase (MocA) was identified as the enzyme responsible for the initial hydroxylation of E1. The findings provide insight into the molecular mechanism of E1 catabolism and suggest potential applications in bioremediation.

Biological saccharification coupled with anaerobic digestion using corn straw for sustainable methane production

Chengjiao Xu et al.

Summary: This study used accumulated fermentable sugars from biosaccharified corn straw to generate methane through anaerobic digestion (AD). It was found that biosaccharification pretreatment expanded corn straw (BECS) treated with Clostridium thermocellum XF811 accumulated reducing sugars with a yield of 94.9 mg/g. The BECS used for AD converted into a high methane yield (7436 mL), which was 49.3% higher than expanded corn straw (ECS). High-throughput microbial analysis revealed the significant contribution of Methanoculleus and Methanobacterium to the high methane yield. Industrial experiments demonstrated a 13.2% increase in methane production from BECS compared to ECS. Biosaccharification pretreatment accelerated ECS destruction and accumulated sugars, thereby increasing methane yields. This study provides a strategy for producing clean energy from lignocellulosic biomass.

Relationship between soil bacterial communities and dissolved organic matter in a subtropical Pinus taiwanensis forest after short-term nitrogen addition

Xiaochun Yuan et al.

Summary: This study investigates the effect of nitrogen addition on forest soil bacterial communities, dissolved organic matter (DOM) components, and their relationships. The results show that low levels of nitrogen addition lead to eutrophication of the surface bacterial community and a decrease in diversity. Short-term nitrogen addition decreases dissolved organic carbon content but increases DOM humification degree. Key bacterial taxa are associated with specific DOM components, and nitrogen addition helps regulate the interactions between soil bacterial communities and DOM.

Summary: Ball milling of biochar can effectively improve its adsorption capacity for VOCs. The specific surface area and total pore volume of ball milled biochar increased, and the adsorption capacities increased by 1.96-3.97 times compared to pristine biochar. Ammonium hydroxide modification increased the adsorption capacities of ball milled biochar by 1.33-1.97 times, while hydrogen peroxide modification decreased the adsorption capacities. The pseudo-second order model fitted better for ball milled biochar at 300℃, while the pseudo-first order model fitted better at 600℃.
