Semi-continuous pilot-scale microbial oil production with Metschnikowia pulcherrima on starch hydrolysate

摘要

Batch cultivation of Metschnikowia pulcherrima on glucose syrup on the 2-L scale. a Profiles of dry cell weight, glycerol and saccharide concentrations, b saccharide uptake rates, and c lipid production rate and lipid content in stirred tank reactor fermentations of an evolved M. pulcherrima strain on glucose syrup and yeast extract (duplicate, mean ± standard error). Dashed lines and empty symbols: nitric acid pH regulation; solid lines and filled symbols: phosphoric acid pH regulation. For clarity, error bars are omitted where rates are displayed. DP degree of polymerisation
