Effect of inoculum size and glucose concentration for bacterial cellulose production by Lactobacillus acidophilus

Bacterial cellulose (BC) has gained interest as new industrial materials because of its unique properties compared to other cellulose sources. Intense researches have been done to study the production of BC and finding a new strain source to meet the requirement of high yield of production with a lo...

Further study on other cultivation parameters is essential for the optimization of BC production by this L. acidophilus strain.
