Total sugars (glucose and xylose) were analyzed by an HPLCusing high performance carbohydrate column (Waters) at 30 °Cwith acetonitrile and water mixture (75:25) as a mobile carrier at aflow rate of 1.4 ml min 1 and detected by a Waters 2414 refractive
index detector. Ethanol in the broth and condensate was analyzedby a gas chromatograph using Ashco Neon II Gas Analyzer with a2 m long and 1/8 in
