“…Many strains originating from various natural and anthropogenically-shaped environments, such as wastewater or polluted soil, exhibit an extensive repertoire of enzymatic properties, which are attractive from a biotechnological perspective [9][10][11]. The reported metabolic properties include the ability to utilize many pollutants (e.g., pesticides, herbicides, and dimethylamine) and the biotransformation of toxic metal ions [12][13][14][15]. It is important to mention that some strains of Ochrobactrum spp.…”

The Ochrobactrum genus consists of an extensive repertoire of biotechnologically valuable bacterial strains but also opportunistic pathogens. In our previous study, a novel strain, Ochrobactrum sp. POC9, which enhances biogas production in wastewater treatment plants (WWTPs) was identified and thoroughly characterized. Despite an insightful analysis of that bacterium, its susceptibility to bacteriophages present in WWTPs has not been evaluated. Using raw sewage sample from WWTP and applying the enrichment method, two virulent phages, vB_OspM_OC and vB_OspP_OH, which infect the POC9 strain, were isolated. These are the first virulent phages infecting Ochrobactrum spp. identified so far. Both phages were subjected to thorough functional and genomic analyses, which allowed classification of the vB_OspM_OC virus as a novel jumbo phage, with a genome size of over 227 kb. This phage encodes DNA methyltransferase, which mimics the specificity of cell cycle regulated CcrM methylase, a component of the epigenetic regulatory circuits in Alphaproteobacteria. In this study, an analysis of the overall diversity of Ochrobactrum-specific (pro)phages retrieved from databases and extracted in silico from bacterial genomes was also performed. Complex genome mining allowed us to build similarity networks to compare 281 Ochrobactrum-specific viruses. Analyses of the obtained networks revealed a high diversity of Ochrobactrum phages and their dissimilarity to the viruses infecting other bacteria.

“…The intracellular degrading enzymes of methamidophos have been preliminarily discovered, and the optimum conditions have been explored using the response surface method (Wang et al, 2012;Zhang et al, 2013). Interestingly, some bacteria can degrade a series of organophosphorus pesticides including methamidophos, such as Aspergillus sp., Enterobacter ludwigi M2, and Brevundimonas faecalis MA-B12 (Zhao et al, 2014;Adelowo et al, 2015;Jiang et al, 2019). In particular, Sphingobium sp.…”

“…We emphasize the role of physicochemical degradation and biodegradation for large-scale treatment of acephate and/or methamidophos contamination. However, few reviews have focused on the degradation mechanisms and biochemical pathways of acephate and methamidophos (Maqbool et al, 2016;Kumar et al, 2018;Jiang et al, 2019). We emphasize the role of biodegradation for large-scale treatment of acephate and/or methamidophos contamination.…”

“…Generally, bacterial strains such as Pseudomonas, Bacillus, Rhodococcus, Stenotrophomonas, Alcaligenes, Serratia and Streptomyces have been used in the breakdown of many pesticides (John et al 2016;Gaonkar et al 2019;Jiang et al 2019). Acinetobacter schindleri is a Gram negative, nonmotile, coccobacilli, nonspore forming and aerobic bacterium.…”

Extensive applications of pesticides have led to the contamination of ecosystem. Therefore, the isolation of new pesticide degrading bacteria is important. For the biodegradation of α-endosulfan and α-cypermethrin, new bacteria isolates were isolated from grasshopper (Poecilimon tauricola). According to different tests, these isolated bacteria were identified as Pseudomonas aeruginosa B5, Acinetobacter johnsonii B6, Acinetobacter schindleri B7, Bacillus megaterium B9 and Brevibacillus parabrevis B12. The first two of these bacteria have been isolated as those that can use only α-endosulfan and the last two only use α-cypermethrin. Moreover, A. schindleri B7 was determined to be able to degrade both pesticides. When glucose was added to non-sulfur medium containing α-endosulfan (100 mg/L) and minimal salt medium containing α-cypermethrin (100 mg/L), both pesticide degradation and bacterial growth was increased. As a result, A. schindleri, a new gram negative bacterium, can inevitably be used in the biological treatment of environments exposed to pesticides.
