Y Development Fund plus the Geothermal Study Group (GEORG) Fund.The cell pellets had been collected by centrifugation (1000 ?g for 10 min) at four then extracted with 3ml of ethanol: hexane two:1 (v/v) containing 0.1 (w/v) butylated hydroxytoluene till colorless [34]. Towards the mixed answer, 2 ml deionized water and four ml hexane have been added and the mixture was vigorously shaken and centrifuged once again at 1000 ?g for five min [7]. An aliquot of four ml of the upper hexane layer was evaporated below nitrogen at 25 ?two , reconstituted within a mixture of methyl tertiary butyl ether : acetonitrile (50:50)Fu et al.
