“…The choice of carbon source and fed-batch feeding strategies affects lactic acid production and appears to be a major control mechanism. The lactic acid production (89.2 g/L) observed in this work appears to be much higher than the level obtained from deproteinised whey (46 g/L) and starch (43.7 g/L) ( Roukas and Kotzekidou, 1998 ; Yen and Kang, 2010 ).…”

“…This type of process is generally more efficient than batch and continuous processes, and it is especially beneficial when changes to the nutrient concentration affect the productivity and biomass of the desired product ( Lee et al , 1999 ). However, until now there have been only a few systematic reports on fed-batch fermentation for the production of lactic acid by bacteria ( Roukas and Kotzekidou, 1998 ; Bai et al , 2003 ; Liu et al , 2005 ; Ding and Tan 2006 ; Yen and Kang, 2010 ; Zhang et al , 2011 ).…”

The production of lactic acid from date juice by Lactobacillus caseisubsp. rhamnosus in batch and fed-batch cultures has been investigated. The fed-batch culture system gave better results for lactic acid production and volumetric productivity. The aim of this work is to determine the effects of the feeding rate and the concentration of the feeding medium containing date juice glucose on the cell growth, the consumption of glucose and the lactic acid production by Lactobacillus casei subsp. rhamnosus in fed-batch cultures. For this study, two concentrations of the feeding medium (62 and 100 g/L of date juice glucose) were tested at different feeding rates (18, 22, 33, 75 and 150 mL/h). The highest volumetric productivity (1.3 g/L.h) and lactic acid yield (1.7 g/g) were obtained at a feeding rate of 33 mL/h and a date juice glucose concentration of 62 g/L in the feeding medium. As a result, most of the date juice glucose was completely utilised (residual glucose 1 g/L), and a maximum lactic acid production level (89.2 g/L) was obtained.

Lactic acid is an organic compound produced via fermentation by different microorganisms that are able to use different carbohydrate sources. Lactic acid bacteria are the main bacteria used to produce lactic acid and among these, Lactobacillus spp. have been showing interesting fermentation capacities. The use of Bacillus spp. revealed good possibilities to reduce the fermentative costs. Interestingly, lactic acid high productivity was achieved by Corynebacterium glutamicum and E. coli, mainly after engineering genetic modification. Fungi, like Rhizopus spp. can metabolize different renewable carbon resources, with advantageously amylolytic properties to produce lactic acid. Additionally, yeasts can tolerate environmental restrictions (for example acidic conditions), being the wildtype low lactic acid producers that have been improved by genetic manipulation. Microalgae and cyanobacteria, as photosynthetic microorganisms can be an alternative lactic acid producer without carbohydrate feed costs. For lactic acid production, it is necessary to have substrates in the fermentation medium. Different carbohydrate sources can be used, from plant waste as molasses, starchy, lignocellulosic materials as agricultural and forestry residues. Dairy waste also can be used by the addition of supplementary components with a nitrogen source.

“…However, direct fermentation, which couples the enzymatic hydrolysis and microbial fermentation into a single step by utilising the amylolytic lactic acid bacteria, has received increasing interest. A few amylolytic LAB strains have been isolated such as Lactobacillus amylophilus (Yen & Kung, 2010), Lb. manihotivorans (Guyot et al, 2000;Ohkouchi & Inoue, 2006), Lb.…”

Summary With the advancement in science and technology, the importance of bioconversion of industrial waste into value‐added products through biotechnological route has been realised. Moreover, to make the process economic and environment responsive, agro‐industrial waste/by‐products can be used as substrates in fermentation processes as an inexpensive raw material. In the field of food biotechnology, organic acids represent the third largest category among the biological products, which can be produced chemically or by fermentation process. Among organic acids, lactic acid holds an important position because of its multivariate applications in food, pharmaceutical, cosmetics, textiles and other industries. Traditionally, lactic acid was produced from pure substrates, but agricultural feedstocks and industrial by‐products have evoked the interest of researchers to use them as raw materials for the biotechnological production of lactic acid. The utilisation of biomass has gained major attention due to environmental hazards, scarcity of fossil fuels and meet the increasing world food and feed demand. Integrated biorefinery approaches have also been adopted for the production of lactic acid along with primary product to minimise the cost. This review provides comprehensive information on the recent advances in biotechnological production of lactic acid utilising agro‐industrial waste/by‐products.
