Abstract
Suitability of 5 lactic acid bacteria as starters for acidification and recovery of carotenoids and chitin from shrimp processing waste was investigated. The greatest acid production was achieved with Pediococcus acidolactici strain CFR2182 and surface response methodology was used to determine optimum conditions for acidification by this strain to pH 4.3 0.1. The analysis showed optimum values for fermentation time, sugar concn. and inoculum concn. to be 72 h, 15% glucose and 8.28 log cfu/ml, respectively. The predicted results and the methodology used were subsequently validated. Production of carotenoids and chitin from the shrimp waste by P. acidolactici CFR2182 fermentation was also investigated. Results indicate that 72.4-78.5% of the carotenoids content of the shrimp waste could be recovered. In addition, rates for the removal of proteins and minerals from the waste, as required for recovery of chitin, that were achieved by the bacterium were 97.9 and 72.5%, respectively.
