Factors influencing crude oil biodegradation by Yarrowia lipolytica

The crude oil biodegradation by Fisherella and Nostoc Cyanobacteria

The purpose of this study was to investigate the growth and potential of crude oil biodegradation by Fischerella and Nostoc. In this study, the growth rate of cyanobacterial species such as Fischerella sp. ISC107 and Nostoc sp. ISC101 were determined using chlorophyll-a content measurement at 663nm under different treatments of crude oil (control, 0.1, 0.2, 0.4, 0.8 and 1.6%). The crude oil con...

Oil Production from Yarrowia lipolytica Po1g Using Rice Bran Hydrolysate

The purpose of this study was to produce microbial oil from Yarrowia lipolytica Po1g grown in defatted rice bran hydrolysate. After removing oil from rice bran by Soxhlet extraction, the bran is subjected to acid hydrolysis with various sulfuric acid concentrations (1-4% v/v), reaction times (1-8 h), and reaction temperatures (60-120°C). The optimal conditions for maximum total sugar production...

Immobilization of Yarrowia lipolytica for aroma production from castor oil.

The main aim of this study was to compare different materials for Y. lipolytica immobilization that could be used in the production of γ-decalactone (a peach-like aroma) in order to prevent the toxic effect both of the substrate and the aroma upon the cells. Therefore, cells adsorption onto pieces of methyl polymethacrylate and of DupUM(®) was studied and further used in the biotransformation o...

Crude Oil Biodegradation in the Marine Environments

Biodegradation of Crude Oil by an Artificial Microalgal-Bacterial Consortium

The extensive use of petroleum and petroleum products leads to serious oil contamination of the environment, thus considerable interests were taken in microbial degradation and detoxification of these pollutants. Microalgae play an important role in the environmental cleaning of pollutants. Microalgae provide O2 to aerobic bacteria to mineralize pollutants and then take-up the released CO2 [1]....
