One of the main obstacles in the large-scale production
of this substance is the cost of the raw material.
Application of agro-industrial wastes in bioprocesses
provides an alternative way to replace the
refined and costly raw materials. In addition, the bulk
use of such materials helps to solve many environmental
hazards. However, the application of microorganisms
for the production of lactic acid using
cost-effective raw materials is rare. Hence, research
efforts are focused on looking for new and effective
nutritional sources and new progressive fermentation
techniques, enabling the achievement of both high
substrate conversion and high production (Jawad et
al., 2013).
