Lactic acid production using mango peel. Studies on lactic acid production using mango peel and it’s use in bio-film preparation

      Аннотация: Mango fruit processing industries generate 15-20% of Mango peel and these are rich in sugars. Feasibility of mango peel for lactic acid production of industrially relevant metabolite through fermentation by Rhizopus oryzae NCIM 1009. At 3% peel fermentation of mango peel(MP) yielded 50.8 and 90.3 mg/100 ml of LA respectively and enhanced lactic acid production from mango peel waste focused conventional followed by statistical optimisation by RSM noticed that LA 7.25 g/L of LA from 30 g/L of mango peel, pH 6.0, temperature 30°C in 96 h time. Pre-treatment of the mango peel by liquid hot water (LHW), NaOH and Ca(OH)2 were noticed by delignification and efficient fermentation by more total and reducing sugars. Pre-treated mango peel 50 g/L produced 14 further increased to 70 g/L significant decrease in 9 g/L LA formation. The fermentation characteristics with 50 g/L, LA 14 g/L produced, biomass 3.8 g/L and RS remain 23 g/L in 96h of batch fermentation and reducing sugars leftover were 16 g/L, RS conversion 70% and yield was 37% and productivity 0.54 g/l/h has a significant in mango peel utilisation and reducing sugars formation which in turn led to maximum LA 14 g/L production in 9.
