Annotation	We examined fiber fermentation capacity of 2 captive chimpanzee fecal microflora eating low-fiber diet (LFD) and high-fiber (HFD) diets using four substrates for in vitro gas production of feces. We examined the effects of diets on eubacteria and archaea in feces. Fermentation in LFD resulted in higher dry matter digestibility and gas production than in HFD. HFD increased production of short-chain fatty acids (SCFAs). DGGE of bacterial DNA revealed shift in eubacteria and archaea. A much more complex eubacterial population structure was observed compared with the less variable archaeal population in both diets. Genomic DNA in the dominant eubacterial band in HFD was confirmed to be related to Eubacterium biforme. The predominant band in LFD represented new species of mycoplasms. Fecal microbial populations of captive chimpanzees are not capable of extensive fiber fermentation; however, there was a positive effect of fiber content on SCFA production.
