Lactic acid is an important platform chemical for the production of PLA and other value-added products, and it is naturally produced by various microbes, including bacteria, yeast, and fungi. Bacteria typically ferment C5 and C6 sugars into lactic acid through homo- or hetero-fermentation. Enzymes such as xylose isomerase, phosphoketolase, transaldolase, and l- and d-lactate dehydrogenases play a crucial role in the metabolic pathways of lactic acid production. However, metabolic engineering of microbial strains is often necessary to enable lactic acid production from other carbon sources. The production of d-lactic acid has gained attention due to the demand for thermostable PLA, but large-scale commercial production of d-LA is yet to be realized.
The use of thermophilic strains of Bacillus coagulans for homo-fermentation of lignocellulosic sugars to lactic acid under non-sterilized conditions has limitations due to the lack of genetic tools for metabolic engineering. Pretreatment of agricultural biomass to obtain fermentable sugars is a major challenge in using large amounts of biomass for lactic acid production. Genetic engineering of strains to tolerate acidic conditions and produce lactic acid at low pH could potentially reduce production costs by avoiding or minimizing the use of neutralizing agents during fermentation.
Recent research has focused on the fermentative production of optically pure lactic acid due to its high potential for applications in various fields. The increasing demand for biodegradable PLA materials as eco-friendly alternatives to petroleum-derived plastics has led to a global interest in lactic acid production. However, higher production costs have limited the widespread use of PLA, primarily due to the expensive cost of lactic acid. Therefore, improving lactic acid production and productivity, as well as reducing production costs through the use of inexpensive substrates, have become significant objectives. Several bioprocess techniques involving wild-type and/or engineered microbes have been employed to increase lactic acid production. This review will focus on the characteristics and metabolism of lactic acid producers in relation to fermentation.
In addition to costly pure sugars and food crops, this overview discusses alternatives such as dairy products, food and agro-industrial wastes, algal biomass, and inexpensive fermentative substrates like glycerol. The different fermentation strategies and modes that have been reported to enhance lactic acid production in terms of concentration, yield, and efficiency are summarized and compared. Immobilization and cell recycling methods for high-density fermentation are also discussed. Finally, improvements in recovery procedures and future outlook for lactic acid production are presented.

Growth Drivers
Global lactic acid is a versatile organic acid that has gained significant importance in various industries. Its applications in the food and beverage, pharmaceutical and personal care, and industrial sectors, along with its eco-friendly nature, have been driving its growth and industry importance. With the increasing consumer demand for natural and sustainable products, the demand for lactic acid is expected to continue to grow in the foreseeable future.
the key growth drivers for lactic acid is its widespread use in the food and beverage industry. Lactic acid is used as a food additive, preservative, flavor enhancer, and pH regulator in a wide range of food and beverage products. It is commonly used in dairy products, bakery goods, meat and poultry, confectionery, and beverages, among others. The growing consumer demand for natural and clean label food products has fueled the demand for lactic acid as it is considered a natural and eco-friendly alternative to other food additives.
Another important industry where lactic acid has gained significance is the pharmaceutical and personal care industry. Lactic acid is used in the production of various pharmaceutical and personal care products due to its antimicrobial properties, moisturizing properties, and ability to enhance the bioavailability of certain drugs. It is used in the production of topical creams, lotions, oral care products, and medical dressings, among others. The increasing awareness about the benefits of using natural and sustainable ingredients in pharmaceutical and personal care products has contributed to the growing demand for lactic acid.
Furthermore, lactic acid is also used in industrial applications such as bioplastics, textiles, leather, and detergents, among others. It is used as a raw material for the production of polylactic acid (PLA), which is a biodegradable and renewable bioplastic used in packaging, disposable cutlery, and other plastic products. The growing environmental concerns and regulations promoting the use of sustainable materials have led to increased demand for lactic acid in the production of bioplastics.
In addition to its wide range of applications, lactic acid is also considered an important industry due to its eco-friendly nature. Lactic acid is produced by the fermentation of renewable feedstocks such as corn, sugarcane, and other plant-based sources, making it a sustainable and renewable option compared to other petrochemical-based acids. The growing emphasis on sustainability and the increasing adoption of bio-based products have further boosted the demand for lactic acid in various industries.
