Explanation

It was the first organic acid to be produced from the microbial fermen­tation in starchy and sugary medium. Lactic acid fermentation is carried out by both bacteria (e.g. Streptococcus lactis and Lactobacillus species) and fungi (e.g. Rhizopus). The acid de­rived from fungal sources is costlier but is of high purity.
