“…It is known that the toxicity of the aliphatic hydrocarbons decreases with an increasing number of carbon atoms due to a decrease in their volatility [72]. Over 3 days, the abiotic loss of decane and hexadecane in the system without microorganisms was 62.87% and 1.21%, respectively (Table 9).…”

The application of Gordonia strains in biotechnologies of environmental purification as degraders of pollutants of different chemical structures is an interesting research topic. The strain Gordonia rubripertincta 112 (IEGM112) is capable of utilizing diesel fuel, alkanes, and aromatic compounds. The aim of this work was to study the potential of G. rubripertincta 112 as a degrader of aromatic and aliphatic compounds and analyze its complete genome in comparison with other known G. rubripertincta strains. The genome had a total length of 5.28 Mb and contained 4861 genes in total, of which 4799 were coding sequences (CDS). The genome contained 62 RNA genes in total, of which 50 were tRNAs, three were ncRNAs, and nine were rRNAs. The strain bears plasmid elements with a total length of 189,570 nucleotides (plasmid p1517). The strain can utilize 10.79 ± 1.17% of hexadecane and 16.14 ± 0.16% of decane over 3 days of cultivation. In the genome of the strain, we have found metabolic pathways of alkane (cytochrome P450 hydroxylases) and catechol (ortho- and meta-pathways) degradation. These results will help us to further approach the fundamental study of the processes occurring in the strain cells and to enrich our knowledge of the catabolic capabilities of G. rubripertincta.

“…Crude oil and processed hydrocarbons such as diesel could contain concentrations of heavy metals that can inhibit bacterial growth and affect bioremediation processes. , Knowing if the microorganisms used for a bioremediation process can endure the presence of heavy metals and toxic petroleum compounds and at the same time degrade hydrocarbons is crucial . Various approaches have attempted to broaden the understanding of heavy metal-resistant microorganisms to use them for successful bioremediation of oil-contaminated sites. − Chromobacterium violaceum can withstand heavy metals and can reduce halogenated compounds to less toxic compounds. , Previous studies have mainly focused on the adaptation of C.…”

This study aimed to determine the tolerance of Chromobacterium violaceum ATCC 12472 to diesel. The growth of the strain was evaluated through exposure to various diesel concentrations (1, 2.5, 5, 7.5, and 10% v/v), with continuous monitoring of growth via optical density measurements until the death phase was reached. Employing a logistic model, we analyzed the growth kinetics of C. violaceum and compared them with five other models to comprehend substrate utilization dynamics. Our results indicate that optimal bacterial growth occurred at 2.5% (v/v) or 18,125 mg/L diesel, while both higher and lower concentrations manifested inhibitory and increasingly stressful effects. The Aiba model emerged as the most fitting representation of substrate utilization by C. violaceum. In addition, our findings underscore the remarkable diesel tolerance of C. violaceum ATCC 12472, despite the inherently stressful nature of the medium. This study contributes to the understanding of microbial responses to environmental stressors and highlights the pivotal role of the substrate concentration in influencing microbial growth. These insights have implications for bioremediation strategies and enhance our understanding of bacterial ecological resilience in the presence of hydrocarbon pollutants.
