Lignocellulosic biomass is a renewable resource that can be used for biofuel production with the assistance of cellulolytic anaerobic organisms from fecal material. The ability of fecal material to degrade was shown by the treatment of biomass with giant panda (Ailuropoda melanoleuca)feces, indicating that gut flora may reduce biomass. In our study, eight bacterial groups were enumerated monthly over a fourteen-month sampling of the giant pandas to characterize the gastrointestinal flora. Colony forming units per gram fecal material for Bacteroides spp. ranged in the male and female panda from 102 to 104, values for Clostridium spp. ranged from 102 to 105. The previously unidentified Bacteroides spp. in the giant panda and Clostridium spp. may be useful in the degradation of lignocellulosic biomass and its conversion to biofuels. Further work must be conducted to identify species and to isolate cellulase genes in these organisms; metagenomic work is underway to accomplish these tasks.
