Biotic production of lactic acid by LABs exposed to some carbaryl

The global lactic acid market size was estimated at USD 3.37 billion in 2023 and is expected to grow at compound annual growth rate (CAGR) of 8.0% from 2024 to 2030. This growth is driven by increasing demand from various industries. The demand for lactic acid is also driven by government regulations promoting eco-friendly and sustainable products. The impact of carbaryl, i.e., -naphthyl-Nmethylcarbamate on lactic acid fermentation by some lactic acid bacteria such as Lactobacillus casei NCIM -2063, Lactobacillus pentosus, NCIM-2256, Lactobacillus leichmannii NCIM-2172 and Lactobacillus delbrueckii NCIM-2353 has been studied. The strain Lactobacillus pentosus NCIM - 2256 has been found big lactic acid producer. It has been observed that the carbaryl, i.e., 1- naphthyl-N - methylcarbamate at its concerntration of 7.0×10–5 M enhances the yield of lactic acid to an extent of 16.144 % higher in comparison to control, i.e. 9.675 g/100ml under optimised parametric conditions.
