Investigating lactic acid fermentation from corn cobs hydrolyzed by enzyme VISCOZYME®L
Main Article Content
Abstract
This study conducted the process of hydrolyzed corn-cobs, an agricultural waste source rich in cellulose, by enzyme Viscozyme®L as such to produce glucose-rich hydrolysate, which is then used to replace the commercial glucose in MRS for economic benefits. The above method of fermentation by Lactobacillus plantarum is to collect lactic acid. The results show that Viscozyme®L enzyme concentrations appropriate for corn-cob hydrolysis is 5% (v/v), the obtained product is 63.54 g/l of treated glucose. The sufficient fermentation conditions are 6% (v/v), glucose concentration 6% (w/v), fermentation time 84 hours, and lactic-acid concentration 23.7 g/l.
