“…It has been previously shown [21] that R. qingshengii 7B is a mesophilic strain with a temperature optimum of 28−32 °С. However, further research has shown that its survival limits are rather wide: the strain was capable of growth in a rich medium in the temperature range from 8°C to 55°C.…”

“…The strain has been tentatively identified as Rhodococcus qingshengii 7B based on sequence analysis of the 16S rRNA gene fragment. This strain has been found to be capable of utilizing caprolactam, phenol, benzoate, octane, nonane, decane, hexadecane, dodecane, undecane as growth substrates [21] .…”

“…However, these methods are expensive, including operation and maintenance costs, require large energy inputs, and produce secondary pollution ( Gu et al, 2016 ). Biological treatment technology has great potential and competitive advantages related to environmental safety and friendliness, as it produces no secondary pollution and has a lower cost ( Polivtseva et al, 2020 ). Biological biodegradation has been widely used for removing phenol from a wide range of environments, including soil ( Sharma and Lin, 2017 ; Gong et al, 2021 ), wastewater ( Liu et al, 2016 ; Barik et al, 2021 ), and aquaculture system ( Nandi et al, 2020 ).…”

Phenol is a toxic organic molecule that is widely detected in the natural environment, even in drinking water sources. Biological methods were considered to be a good tool for phenol removal, especially microbial immobilized technology. However, research on the “seed” bacteria along with microbial community analysis in oligotrophic environment such as drinking water system has not been addressed. In this study, Acinetobacter sp. DW-1 with high phenol degradation ability had been isolated from a drinking water biofilter was used as seeded bacteria to treat phenol micro-polluted drinking water source. Meanwhile, the whole genome of strain DW-1 was sequenced using nanopore technology. The genomic analysis suggests that Acinetobacter sp. DW-1 could utilize phenol via the β-ketoadipate pathway, including the catechol and protocatechuate branches. Subsequently, a bio-enhanced polyhedral hollow polypropylene sphere (BEPHPS) filter was constructed to investigate the stability of the seeded bacteria during the water treatment process. The denatured gradient gel electrophoresis (DGGE) profile and the quantification of phenol hydroxylase gene results indicate that when the BEPHPS filter was operated for 56 days, Acinetobacter sp. was still a persistent and competitive bacterium in the treatment group. In addition, 16S rRNA gene amplicon sequencing results indicate that Acinetobacter sp., as well as Pseudomonas sp., Nitrospira sp., Rubrivivax sp. were the predominant bacteria in the treatment group, which were different from that in the CK group. This study provides a better understanding of the mechanisms of phenol degradation by Acinetobacter sp. DW-1 at the gene level, and provides new insights into the stability of seeded bacteria and its effects on microbial ecology during drinking water treatment.
