“…Thermotolerant Actinobacteria such as strains of Streptomyces albus and Streptomyces griseus , and thermophilic Actinobacteria such as Streptomyces , Amycolatopsis , Microbispora , Cellulosimicrobium , Micrococcus , Saccharopolyspora , Micromonospora , Thermobispora , Thermomonospora , Thermobifida , and Planomonospora were reported to be involved in the composting process [ 121 ]. A thermotolerant oil degrading Actinobacteria from the genera Rhodococcus and Gordonia showed ability to grow at up to 10% NaCl and utilize crude oil and individual hydrocarbons at higher (up to 50 °C) temperatures [ 122 ]. However, all rubber-degrading species described so far are mesophilic, with only one exception, identified as a Streptomyces sp.…”

Rubber is an essential part of our daily lives with thousands of rubber-based products being made and used. Natural rubber undergoes chemical processes and structural modifications, while synthetic rubber, mainly synthetized from petroleum by-products are difficult to degrade safely and sustainably. The most prominent group of biological rubber degraders are Actinobacteria. Rubber degrading Actinobacteria contain rubber degrading genes or rubber oxygenase known as latex clearing protein (lcp). Rubber is a polymer consisting of isoprene, each containing one double bond. The degradation of rubber first takes place when lcp enzyme cleaves the isoprene double bond, breaking them down into the sole carbon and energy source to be utilized by the bacteria. Actinobacteria grow in diverse environments, and lcp gene containing strains have been detected from various sources including soil, water, human, animal, and plant samples. This review entails the occurrence, physiology, biochemistry, and molecular characteristics of Actinobacteria with respect to its rubber degrading ability, and discusses possible technological applications based on the activity of Actinobacteria for treating rubber waste in a more environmentally responsible manner.

“…The strain Par7 utilized 15% of the crude oil over 14 days at a temperature of 45°C and an initial oil concentration of 2% (w/v). Sharma and Pant [52] reported that the Rhodococcus strain grew in the medium with crude oil at a temperature of 37°C, but at higher temperature cells could not grow. Rhodococci have extreme metabolic flexibility and are able to utilize pollutants of different origin, including hydrocarbons and their derivatives.…”

Gordoniae are one of the most promising hydrocarbon‐oxidizing actinobacteria. Here we present the genome sequence analysis of thermotolerant strain Gordonia sp. 1D isolated from oil‐refinery soil. It is capable of alkane consumption and biosurfactant production at temperatures of up to 50°C. Gordonia sp. 1D demonstrates maximum biosurfactant production when grown on hexadecane, and at 40°C it was slightly higher than at 27°C: 35 and 39 mN/m, respectively. For the first time, it was experimentally confirmed that the carbohydrate component of extracellular biosurfactants produced by strain 1D is trehalose. In addition, genes for the production of trehalose lipid biosurfactants were identified. The genetic determinants for two different pathways for trehalose synthesis were found. The strain carries genes otsA and otsB involved in de novo trehalose biosynthesis. Moreover, the genes treY and treZ responsible for trehalose biosynthesis from maltooligosaccharides and starch or glycogen were identified.
