Abstract
The rise in accumulation of agricultural wastes has demanded ways of effectively utilising this waste and converting them into useful products. A large portion of the agricultural waste comprises of lignocellulose. Lignocellulose, being the most abundant carbon source available, can be used as a substrate to convert into useful products like lactic acid and ethanol. However, lignocellulose bio-conversion comes with its own challenges, mainly due to its complex structure. There are several parameters affecting the efficiency of bioconversion of lignocellulose into lactic acid. This review will focus on one of the parameters involved i.e., the effect of oxygen in facilitating the efficient conversion of lignocellulose into lactic acid. Studies have shown that the yield of lactic acid is high-er when the fermentation is carried out under anaerobic conditions. The review also touches upon the different methods and compounds used for switching between aerobic and anaerobic conditions.
