Bacterial Lactic Acid Production for Bioplastic Industry
Abstract
The environmental and economic challenges have provoked the society to partially substitute the petrochemical-based polymers with the biodegradable ones. Polylactic acid (PLA), made from polymerization of lactic acid, is an eco-friendly biodegradable plastic. PLA has potential for use in a wide range of applications. Those include packaging, medical, agriculture, transportation, building, and electronics. As aforementioned, the substituting PLA in the plastic industry has generated the market demand for lactic acid, the PLA building block. Lactic acid can be produced either by chemical synthesis or microbial fermentation. Nonetheless, an optical purity of lactic acid is mandatory in PLA synthesis; therefore, microbial fermentation with the certain strains is considered suitably. Many wild-type and engineered microbes that were capable of producing lactic acid both D- and L-isomers have long been reported in many literatures. Those, for example, include lactic acid bacteria (LAB), Escherichia coli, and Corynebacterium glutamicum. Among those, Bacillus and Sporolactobacillus showed the great potential to produce lactic acid with high production rate and optical purity. Herein, we summarized the list of lactic acid producing microbes that showed the industrial potential. Also, the screening and selection of the industrial strains and the fermentation methods that provided the improved lactic acid production performance were addressed. Keywords : lactic acid, lactic acid bacteria, bioplastic, polylactic acidReferences
