Potato peel waste (PPW), almond shells (AS) and spent coffee grounds (SCG) are such wastes and were used as feedstocks to produce lactic acid (LA) via fermentation. Two lactic acid producing bacterial consortia were screened/selected based on glucose and arabinose fed media and were each used for subsequent fermentations. The food wastes were subjected to either: (i) starch gelatinization, (ii) hydrothermal pretreatment, (ii) hydrothermal and cellulase pretreatment, and (iv) hydrothermal and cellulase pretreatment buffered with CaCO3 prior to fermentation. The glucose selected consortia was better than the arabinose selected consortia for generating LA, and thus was used for further fermentations trials using pretreated biomass. The best LA yield (0.175 g LA g-1 biomass) was from gelatinized AS than the hydrothermal plus cellulase pretreatment. LA productivity was improved for the hydrothermal plus cellulase pretreated biomass by addition of CaCO3 as buffer to give LA production rates of 0.063 g LA g-1 PPW, 0.045 g LA g-1 AS and 0.049 g LA g-1 SCG.","PeriodicalId":12351,"journal":{"name":"Fermentation Technology","volume":"169 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79065233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Strains L-120 and AY103 are similar to Enterococcus casseliflavus and Enterococcus faecalis, respectively, as determined by 16S rRNA gene sequencing. It was found that wheat bran hydrolysate (1.5 or 3.0% dry w/v) strongly stimulates the production of lactic acid in both strains. Strain L-120 produced 149 g L-1 L-lactic acid at 35°C under pH 9 from 180 g L-1 glucose with the production rate of 3.9 g L-1 h-1. Strain AY103 produced 153 g L-1 L-lactic acid from 180 g L-1 glucose with the production rate of 4.2 g L-1 h-1. Both strains produced high-optical-purity (100%) L-lactic acid. In addition, strain L-120 produced 12% (w/v) L-lactic acid from degraded inedible materials, i.e., rice straw and soy bean curd refuse, within 72 h under unsterilized conditions. The obtained results indicate that these two strains are very useful for Llactic acid production with the advantages of high productivity and rapid production with reduced costs of product purification, raw materials and fermenter sterilization.","PeriodicalId":12351,"journal":{"name":"Fermentation Technology","volume":"2 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90294781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
