Influence of Tween 80 on degradation of 4-butylphenol at low temperature conditions by Penicillium sp. CHY-2 isolated fromAntarctic soil

Abstract

 Division of Sustainable and Environmental Engineering, Collage of EnvironmentalTechnology, Muroran Institute ofTechnology In this paper, we evaluated the degradation of alkylphenols at low temperature conditions (4°C) by the combined used of Tween 80 and fungus Penicillium sp. CHY-2 which was isolated from non-contaminated Antarctic soil. Growth of CHY-2 strain and degradation of 4-butylphenol (4-BP) at low temperature was promoted by the addition of Tween 80. Degradation rate of 4-BP was improved about 3 times by addition of Tween 80. Furthermore, Tween 80 was effectively used as a carbon source by CHY-2 strain. Results indicated that Tween 80 is a suitable carbon source than glucose for degradation of 4-BP and growth of CHY-2 strain. Moreover, in addition to the role of carbon source, Tween 80 may also promote the uptake of glucose into intracellular level.
