“…In [14], 4 strains belonging to the genera Rhodococcus and Pseudomonas, which destroy 40 % of oil, were isolated, and the degradation of oil, fuel oil, benzene, and ethanolbenzene at 4-6 °C was studied using them. It was shown that the maximum destruction of fuel oil and ethanolbenzene was observed in a strain belonging to the genus Pseudomonas and amounted to 17.2 and 5.2 %.…”

The object of the study is microorganisms isolated from the Azerbaijani territory of the Caspian Sea, capable of decomposing oil and oil products at low temperatures of 4–6 °C. The purpose of this work was to study bacteria and fungi capable of actively assimilating oil, gasoline, kerosene, diesel fuel at a temperature of 4–6 °C in order to solve the problem of environmental pollution in this region. The studied most effective biodestructors are combined into associations that can be used to create an active biological product based on native microorganisms with its further use for water bioremediation, as well as treatment of tanks and other containers used for long-term storage of petroleum products at a temperature of 4–6 °C. The process of degradation of samples of used oils at the molecular level of the selected compounds was studied by reverse-phase high-performance liquid chromatography. As a result of chromatographic and spectroscopic studies, it was found that almost all microorganisms decompose the tested oil products. Only weak peaks remained on the chromatogram, which is a clear indicator of the deep biodegradation carried out by these microorganisms. Thanks to the chromatographic and spectral analysis of oil and products of its decomposition, an oxidation sequence has been established, indicating the decomposition of the last aromatic fraction. As a result, a general picture was obtained on the amount of degradation products containing carboxyl, keto-, hydroxyl groups, which is not enough to determine the processes of transformation of initial products into final ones. All this testifies to the multidirectionality of biodegradation processes

Cold active lipases – an update

Cold active lipases (CLPs) are gaining importance nowadays as they are increasingly used in fine chemical synthesis, bioremediation, food processing and as detergent additive. These enzymes exhibit high catalytic activity at low temperatures and flexibility to act at low water medium. Since they are active at low temperatures consume less energy and also stabilize fragile compounds in the reaction medium. CLPs are commonly obtained from psychrophilic microorganisms which thrive in cold habitats. Compared to mesophilic and thermophilic lipases, only a few CLPs were studied and industrially exploited so far. CLPs (C. antarctica lipase-A and C. antarctica lipase-B) from Candida antarctica isolated from Antarctic region are the well studied and industrially employed, and many are being followed up. This review updates the CLPs reported recently and the industrial applications of CLPs. ARTICLE HISTORY

“…23 mN/m (de Carvalho et al, 2009 ). Adding to this remarkable pleiotropic metabolic behavior, some Rhodococcus species are psychrotrophic and/or are able to endure desiccation conditions, which makes this genus important for bioremediation in cold (Yagafarova and Skvortsova, 1996 ; Belousova and Shkidchenko, 2004 ) and/or arid climates (Pucci et al, 2000 ). The adaptation abilities of these cells have also been used to adapt a mesophilic strain to extreme conditions of temperature and pH and to the presence of high amounts of sodium chloride and copper sulfate (de Carvalho, 2012 ).…”

Membrane transport systems and the biodegradation potential and pathogenicity of genus Rhodococcus

et al. 2014

View full text Add to dashboard Cite

The Rhodococcus genus contains species with remarkable ability to tolerate toxic compounds and to degrade a myriad of substrates. These substrates have to cross a distinctive cell envelope dominated by mycolic acids anchored in a scaffold of arabinogalactan covalently attached to the cell wall peptidoglycan, and a cellular membrane with phospholipids, whose composition in fatty acids can be rapidly altered in response to environmental conditions. The hydrophobic nature of the cell envelope facilitates the entrance of hydrophobic molecules but some substrates require active transport systems. Additionally, toxic compounds may also be extruded by energy spending efflux systems. In this review, physiological evidences of the use of transport systems by Rhodococcus strains and genomic studies that corroborate their existence are presented and discussed. The recently released complete genomes of several Rhodococcus strains will be the basis for an in silico correlation analysis between the efflux pumps present in the genome and their role on active transport of substrates. These transport systems will be placed on an integrative perspective of the impact of this important genus on biotechnology and health, ranging from bioremediation to antibiotic and biocide resistance.
