Economical Lactic Acid Production and Optimization Strategies

  • Sheelendra M. Bhatt
Part of the Fungal Biology book series (FUNGBIO)


The best replacement of plastic is bioplastic. Lactic acid is a promising monomer of polylactide production. Therefore, lowering down lactic acid cost is a challenge. Biochemical production of lactic acid via starch or glucose is not economical. Therefore, the current chapter addresses strategies in economical lactic acid production using fungi, which is still looking for its place in the industry. Lactic acid bacteria (LAB) or fungi have their own merits and demerits. Fungi have several advantages against LAB, such as robust metabolic pathway, suitable for conversion of a diversity of substrates into lactic acid. Therefore, understanding of metabolic pathways and metabolic engineering strategies is crucial in developing a novel strain and increasing the yield of lactic acid. The central role of fungi especially Rhizopus has been discussed in detail. Simultaneous saccharification and fermentation is advantageous, and various factors affecting fermentation have also been discussed in detail. These factors are helpful in optimizing media conditions for reactors.
