Datra and Batra (1979) found all combs had loss cellulose than the raw materialso This would indicate swo prior digestion of cellulose may occur before It reaches the c(=bo White rotting fungi have different strategies as to how they attack lignin and cellulose* but one of the taost usual In to attack lignin firsts followed by cellulose and this probably occurs In the comb. It to likely that different termites have different strategies. In species where the food in mixed with TemitomXces In the Cut it Is likely that some decomposition occurs prior to deposition on the fungus comb, 340e The most likely scheme may be that the zmterial in deposited on the comb by the foragers with more or less Intact lignin, with perhaps some accessible cellulose having been digested* Comminution of plant material by termites will rupture cell walls exposing cell contents to the action of gut enzymes or enzymes of Termltggyces In the out. This lit an Important difference from "straightl wood decay by fungle Termitgw con then breaks down the lignin cellulose complexes, the termites reeat the comb with fungal material and cellulose digestion In completed* Cellulo- lytic bacteria have been Isolated from the comb (Batra and Datra 1979).
