    Abstract: A cellulase producing clostridium sp. strain is screened by (a) mixing sample, e.g. waste water of cowshed, with cellulose-contg. medium, (b) heating the mixt. at 80 deg.C for 15 mm. and culturing, (c) innoculating the cultured broth in the medium contg. 0.1-0.2 % glucose, cellulose and agar, and (d) culturing it for 7-10 days and selecting the straing having a strong cellulase activity, clostridium sp. SC221 (KCTC 8440) (I). The spore of (I) is obtd. by culturing in the medium contg. 0.5 % cellobilose, 1.0 % glucose, 1.0 % cellulose, 0.5 % peptone, 0.5 % trypticase, mineral etc.. The obtd (I) or spore of (I) is useful for feed additive.

    Abstract: Butanol or ethanol is prepd. by culturing clostridium acetobutylicum KFCC1037 (I) in the medium contg. residual product contg. lactic acid (corn steep liquor) or residual product from palm oil production as a nitrogen source. The production rate is increased by mixed culturing (I) and lactic acid bacteria, e.g. Lactobacillus plantarum KCTC3102 or Leuconostoc mesenteroides KCTC3100. Butanol production in the butanol ethanol fermentation is increased by adding lactic acid, corn steep liquor etc.
