and fructose+lactose gave cellulose yield of 6.38 and 5.44 g/L [11]. The
strain isolated by these workers was from nata (desert) and always been
maintained in sucrose containing medium. Also, nata has always been
produced using sucrose as the carbon source. Several have reported
the presence of invertase in some strains of A. aceti and A. xylinum.
The presence of such enzyme would seem to be required for metabolic
utilization of sucrose. Our isolate was also obtained from nata sample
and could able to use the disaccharides effectively for cellulose
production. The effect of two sugars which gave the highest yields of
cellulose was examined.
