Abstract

1,211,845. Yeast &c. BRITISH PETROLEUM CO. Ltd. Dec.12, 1967 [Jan.18, 1967(2)], Nos. 2580/67 and 2582/67. Heading C6F. A micro-organism containing material including (1) an evaporable material such as hexane, ethanol, propanol, isopropanol and butanols, and (2) water, the amount of water being greater than 20% based on the dry weight of the micro-organism and the amount of evaporable material being not more than 50% by weight of the water, so treated, as by drying, to remove part or the whole of the evaporable material while maintaining at least 20% of water based on the dry weight of the micro-organism, in association with the micro-organism. Examples are directed to the drying of pastes of the yeast Candida lipolytica contaminated with hexane and isopropanol used in the extraction of residual hydrocarbon from the micro-organism. The drying was carried out in either a tray dryer having a heated surface swept by 4 scraper dispatchers, or a screw conveyer dryer having a jacketted trough covered by a lid.
