In the era of sustainable development there is a necessity to produce biodegradable polymers to minimize the soil pollution. With the need of the hour Green plastic is the polymeric material formulated for specific applications, which is derived from the Tamarind seed de-oiled cake starch. Through the series of unit operations, starch which is produced can be fermented by Lactobacillus delbrueckii, Lactobacillus amylophylus and Lactobacillus amylovirus. The polymerization reaction of Lactic Acid is carried out by using a catalyst. To cope up with the scarcity of valuable petroleum product & to minimize the environmental pollution, Green plastic materials play an important role for sustainable development.

“…In addition, 91% conversion of raw substrate with such high inulin content into lactic acid is not reported to date. To be commercially applicable, a strain for the industrial LA production should produce more than 100 g/L of LA, with a high yield, at near maximal theoretical value, a high optical purity of LA, and a high productivity in cheap media (Litchfield, 2009). The combination of a strain and novel carbon source proposed here entirely covers these efficiency criteria.…”

“…polymer-grade), residues are not a suitable resource. Therefore, the LA obtained from potato residues should rather be used for technical applications, like textile dyeing and finishing, leather softening, descaling and cleaning in the oil industry 14 . Furthermore, there is a demand for the derived lactate esters, which can be utilized as solvents and cleaning agents in the paint and ink industry or in microelectronics.…”

“…However, the LA concentrations reached in the abovementioned studies are limited to 10-60 g L -1 , which is not comparable with conventional production processes. The approach for this study is to develop a process that reaches titers higher than 100 g L -1 and yields higher than 90 %, as crucial requirements for process economy 14 . The aim of this study was the valorization of potato residues as feedstock for the fermentative production of LA with Lactobacillus casei.…”

Every year large amounts of residues accumulate from potato processing. The aim of this study is to develop a process to valorize these residues as feedstock for lactic acid fermentation in a way that is suitable for industrial production. An enzymatic hydrolysate obtained from potato residues (46 % w/w dry mass starch) was used as a substrate in batch and fed-batch fermentations with Lactobacillus casei. Supplementation of yeast extract (3 g L ) was required to improve productivities. Despite the inhibitory effect exerted by phenolic compounds in the medium, reasonably high lactic acid concentrations (102 g L -1 ) and yields (92 %) were obtained, with 92 % (L-isomer) optical purity. It was clearly demonstrated that potato residues are suitable as feedstock for large-scale production of technical grade lactic acid and that the developed process is promising for large-scale biorefinery applications.
