Bats (Order Chiroptera) are a widely distributed group of mammals. Pteropus giganteus belongs to the Suborder Megachiroptera. This bat consumes fruits and leaves as their major food. Cellulose and xylan are the major composition of leaves. As they consume leaves in their diet, their digestive tract must contain cellulolytic and xylanolytic bacteria which help in the digestion of cellulose and xylan. The cellulolytic and xylanolytic bacteria were isolated and screened on Berg's agar containing cellulose and xylan. The bacteria isolated were characterized biochemically and found to be Proteus vulgaris, Proteus mirabilis, Citrobacter freundii, Serratia liquefaciens and Klebsiella oxytoca. These bacteria help in digestion of cellulose and xylan in the diet of the bat, P. giganteus. Here we show that leaves are also used as a carbohydrate source by these bats. An insectivorous bat, Hipposideros fulvus, was used as a control and does not possess cellulolytic and xylanolytic bacteria. (C) 2004 Elsevier Inc. All rights reserved.
