Abstract

Yeasts from the digestive tract of Ips sexdentatus were isolated. Four strains, representing the different identified yeast species, were chosen. Their enzymatic activity on oligosaccharides, heterosides and polysaccharides was measured. Moreover, we showed that they excrete some B group vitamins which are necessary for the insect, unable to synthesize them.
