Supplementation of sugarcane molasses for maximization of ethanol production by Saccharomyces cerevisiae using response surface method

Year: 2019

Type: article

Abstract: Dilute sugarcane molasses containing 19.2% fermentable sugars was supplemented with (NH 4 ) 2 SO 4 , KH 2 PO 4 , and MgSO 4 • 7 H 2 O to maximize the ethanol production by Saccharomyces cerevisiae TISTR 5596 using a central composite design of response surface method.The maximum ethanol (87.28 g/l) was produced when the dilute molasses was supplemented with 417 mg/l NH + 4 , 1.88 g/l PO 3- 4 and 5 mg/l Mg 2+ .The Ca 2+ contaminated in the molasses was proposed as an indicative index for the requirement of phosphate and Mg 2+ supplementation to maximize the ethanol production.
