Bioconversion of agro-wastes into acetone butanol

Summary Agricultural residues such as bagasse and rice straw have been hydrolyzed by mixed culture filtrates of T. reesei and A. wentii to obtain fermentable sugars. After the hydrolyzate had been treated to remove undesired impurities, Cl. saccharoper butylacetonicum was used to produce butanol to the extent of 16 g/l.     

Effect of oligomannoside-type glycopeptides in diarrheal disease of rabbits induced by Escherichia coli strain RDEC-1

We examined the effects of a soluble receptor-like complex carbohydrate (an oligomannoside-type glycopeptide) on adherence of a type 1 fimbriated rabbit enteropathogen, Escherichia coli strain RDEC-1. Oligomannoside-type glycopeptide, but not a non-glycosylated peptide mixture used as control, inhibited adherence of type 1 fimbriated RDEC-1 to both rabbit ileal brush borders and guinea pig erythrocytes in vitro. In contrast, during RDEC-1 infection of rabbits the receptor-like oligomannoside did not affect the presence and severity of diarrhea, fecal shedding of organisms, luminal colonization by RDEC-1, or enteroadherence of organisms.
