Alcaligenes faecalis is an opportunistic pathogen exhibiting drug resistance. Here, the 35,451-bp genome of phage Piluca is described. Piluca is not closely related to any isolated phages in the NCBI database. Piluca possesses genes encoding CI-like and Cro-like repressors and a tyrosine integrase, suggesting its temperate lifestyle.

Microcystin LR (MC-LR) pollution is a serious threat to aquatic ecosystems and public health in China and is an environmental problem that urgently needs to be solved. However, few studies have investigated the anaerobic degradation pathway and related molecular biological mechanisms of MC-LR. In this study, a bacterium capable of degrading MC-LR with a degradation efficiency of 0.

Nitrification by heterotrophic microorganisms is an important part of the nitrogen cycle in the environment. The enzyme responsible for the core function of heterotrophic nitrification is pyruvic oxime dioxygenase (POD). POD is a non-heme, Fe(II)-dependent enzyme that catalyzes the dioxygenation of pyruvic oxime to produce pyruvate and nitrite.

The recruitment of the phosphorus-solubilizing rhizobacteria plays an important role in response to phosphorus deficiency. Through the treatments of Arabidopsis thaliana (Col-0) and the FERONIA (FER) functional deficient mutants (fer-4 and fer-5) with the soil suspension in various phosphorus conditions, we discovered that FER could promote phosphorus-solubilizing rhizobacteria enrichment to rescue the defective plant during phosphorus deficiency. The amplicon sequencing data reflected that the phosphorus-solubilizing rhizobacterial genus Alcaligenes was significantly enriched of Col-0 than fer-4 in low phosphorus conditions.

Bioaerosol studies showed that wastewater treatment plants (WWTPs) are a significant source of bioaerosol emissions. In this study, 170 samples of total bacteria, total coliform, and total fungi were collected from 10 sites within a domestic WWTP, Alexandria, Egypt, using the sedimentation technique. According to the Index of Microbial Air Contamination (IMA) classes, the total bacteria range was 108-5120 CFU/dm/hour, and all samples were classified as "very poor" except one sample of an office, which was classified as "poor.

The endophytic microbes play crucial roles to crop development under stress environmental conditions. In this research, 36 endophytic bacterial strains having diverse morphology were isolated from exotic wild plant . The strain SSP8 was selected for experimental study as it efficiently tolerate NaCl (0-1200 mM), produced Indole-3-acetic acid (IAA) (46 μg mL) and 1-amino-1-cyclopropane-1-carboxylate (ACC) deaminase (176.
