“…Identification conducted via 16S rRNA gene sequencing showed a closer relation with the bacteria from the genera Priestia (previously Bacillus) [36], Stenotrophomonas, and Pseudomonas, which, in addition to Achromobacter (included in this study), are known as microorganisms that are capable of degrading different classes of pesticides, including methyl parathion, chlorpyrifos, dimethoate, atrazine, and IPR, among others [15,37,38]. This agrees with the phylogenetic analysis of isolates, which showed a closer relation with amide-moiety pesticide-degrading bacteria (Figure S2).…”

The fungicide iprodione (IPR) (3-(3,5-dichlorophenyl) N-isopropyl-2,4-dioxoimidazolidine-1-carboxamide) is a highly toxic compound. Although IPR has been restricted, it is still being applied in many places around the world, constituting an environmental risk. The biodegradation of IPR is an attractive option for reducing its residues. In this study, we isolated thirteen IPR-tolerant bacteria from a biopurification system designed to treat pesticides. A study of biodegradation using different strains was comparatively evaluated, and the best degradation rate of IPR was presented by Achromobacter sp. C1 with a half-life (T1/2) of 9 days. Based on a nano-LC-MS/MS analysis for the strains, proteins solely expressed in the IPR treatment were identified by highlighting the strain Achromobacter sp. C1, with 445 proteins primarily involved in the biosynthesis of secondary metabolites and microbial metabolism in diverse environments. Differentially expressed protein amidases were involved in six metabolic pathways. Interestingly, formamidase was inhibited while other cyclases, i.e., amidase and mandelamide hydrolase, were overexpressed, thereby minimizing the effect of IPR on the metabolism of strain C1. The dynamic changes in the protein profiles of bacteria that degrade IPR have been poorly studied; therefore, our results offer new insight into the metabolism of IPR-degrading microorganisms, with special attention paid to amidases.

Worldwide biodiversity is impacted strikingly by global environmental change, and thus its impact is reflected in all life aspects. Identifying microorganisms in environmental samples, particularly soil could be a valuable interest to study their effect on soil quality and plant growth. Through this study, we conducted a molecular characterization of bacteria found in the rhizosphere of Medicago sativa plants grown in Hai'l soil and we highlighted their main properties. The analysis of sequences revealed that the main bacterial isolates were Pseudarthrobacter, Metabacillus, Priestia, and Massilia species. According to the sequence analyses and the phylogeny tree results, some of the identified bacteria were classified at the species level: one of the pseudarthrobacter isolates was identified clearly as Pseudarthrobacter phenanthrenivorans; Metabacillus isolates grouped with Metabacillus sediminilitoris and the two Priestia isolates closely related to Priestia aryabhattai. We concluded that Hai'l soil is a niche of diverse bacteria with a high interest in soil environment and ecosystems. Further studies are required for further classification of all identified bacteria and to define their specific role in the environment.

“…Existing studies are related to its potential for decontamination processes in pesticide‐polluted soil. The results showed that the bacteria could produce hydrolytic enzymes to transform protein into amino acids (Le et al., 2021; Pathak et al., 2020). Therefore, this study aimed to determine the potential of P. aryabhattai in degrading fecal sludge from septic tank.…”

The significant potential of microorganisms for fecal sludge degradation is an interesting area for investigation, primarily due to its current lack of attention. This study involved the identification of indigenous bacteria in septic tank fecal waste with the Polymerase Chain Reaction (PCR) 16S rRNA gene. Subsequently, selected bacteria strains were subjected to a potential assessment using a single method. Variables in this experiment included the addition of 2% (v/v) bacteria and sample sterilization. The results showed that the use of PCR 16S rRNA analysis led to the identification of Priestia aryabhattai, a member of the phylum Firmicutes, as the dominant species in the samples. This bacteria exhibited adaptability to both aerobic and anaerobic conditions. Sterile samples with the addition of P. aryabhattai 2% (v/v), showed the best removal efficiency percentages of 79.77%, 79.62%, 62.91%, and 70.48% for Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), and Volatile Suspended Solids (VSS). Meanwhile, the total carbon and nitrogen decreased to 2895 mg/L C and 794.12 mg/L NH3‐N, respectively. Based on the results, Priestia aryabhattai has the potential to degrade organic waste but is not suitable for fecal sludge.
