Designing Economical Production of Microbial Cellulose from Waste Using Modified Bioreactor (original) (raw)

Abstract

Microbial cellulose produced by Acetobacter xylinum is an alternative source for plant cellulose in industrial use. Production of microbial cellulose is receiving great attention since they can be applied in many fields. This research is carried out to study the production of microbial cellulose using Rotary Discs Reactor (RDR) by Acetobacter xylinum bacteria in pineapple waste medium. RDR is a new method developed to enhance the production of microbial cellulose in industrial field because of few advantages: it allows the oxygen enrich air to be supplied continuously, homogenized culture in the medium by rotating discs and less hassle to scale up. This research involved few experimental works including fermentation process, comparison of the production yield from static culture and RDR using similar medium, and glucose analysis. The fermentation process was carried out at room temperature, pH 5.0, rotary speed at 7 rpm and 4 days of fermentation. The variable parameter in this rese...
