Which among the following organic acids is fermented by both bacteria and fungi?
-
Citric acid
-
Lactic acid
-
Gluconic acid
-
Butyric acid
-
Acetic acid
B
Correct answer
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.
