Advances in biotechnological processes for lactic acid production

Synthesis of lactic acid from petrochemicals has been cancelled and since 2011 the lactic acid has been exclusively produced by biotechnological processes - fermentation of glucose, sucrose or lactose by different microorganisms. Traditional use of the lactic acid and, nowadays, production of other chemicals and biodegradable polymers from the acid drive global lactic acid demand. Leading producers are investing in development of new bioprocesses for the lactic acid production from renewable raw materials by microorganisms which possess hydrolytic and fermentative activity. Main objective of investigation was development of new bioprocess that meets the European Union climate and energy goals - „20/20/20“ targets and the strategy „Innovating for Sustainable Growth: a Bioeconomy for Europe”. Application of novel highly efficient and sustainable bioprocess and construction of industrial plant for the lactic acid production depends on type of raw material to be used in market established manner in the European Union area. The new bioprocess of simultaneous saccharification of semi-solid substrate and fermentation to the lactic acid by amylolytic lactic acid bacterium was developed. The bacterium also possesses proteolytic activity and it can use proteins from the raw material as amino acid source. The developed bioprocess is suitable for scale up and it can be integrated in zero waste biorefineries in which other biochemical and biofuels can be produced from the renewable raw material.
