Azobenzene exerted no significant effect on the dynamics and the species composition of the saprophytic soil bacterial complex, which remained almost the same as in the control and was characterized by the predominance of Curtobacterium sp., Arthrobacter globiformis, and Bacillus megaterium in all stages of succession. Some heterotrophic bacteria were found to be able to accumulate azobenzene. Bac. cereus and Bac. polymyxa degraded azobenzene during their cultivation in nutrient media.

Researchers have reported that Bacillus megaterium BM18-2 reduces Cd toxicity in Hybrid Pennisetum, but understanding the interaction between plants and associated endophytes is crucial for understanding phytoremediation strategies under heavy metal stress. The current study aims to monitor the colonization patterns of GFP-labeled endophytic bacteria BM18-2 on Hybrid Pennisetum grass. Additionally, it will monitor Cd's effect on plant bacterial colonization.

The biomethanization of lignocellulosic wastes remains an inefficient and complex process due to lignin structures that hinder the hydrolysis step, therefore, some treatments are required. This work describes the addition of an enriched microbial consortium in the biomethanization of rice straw. The experiment was carried out in lab batch reactors following two strategies: (i) pretreatment of rice straw for 48 h using the enriched microbial consortium (dilution 1:100), and (ii) addition of this enriched microbial consortium (dilution 1:100) directly to the anaerobic reactors (bioaugmentation).

In our study, we analyzed the composition, diversity, and function of soil bacterial communities in alpine meadows at different altitudes and aspects and their relationship with environmental factors. Our results indicate that altitude and aspect orientation significantly influences the diversity index and composition of soil bacterial communities.

Bacterial denitrification is a main pathway for soil NO sinks, which is crucial for assessing and controlling NO emissions. Biobased polyhydroxyalkanoate (PHA) microplastic particles (MPs) degrade slowly in conventional environments, remaining inert for extended periods. However, the impacts of PHA microplastic aging on the bacterial NO sink capacity before degradation remain poorly understood.
