Effect of different additives on the production of bacterial cellulose from pineapple waste
The pineapple peel wastes contain high concentration of biodegradable organic material such as carbohydrate that can be utilized for the production of organic acid.With the goal of being economically competitive and overcome the problem of disposal of the waste,pineapple waste can be potentially use...
