Platform for bio-based production of high levels of o-phosphoserine, cysteate, or taurine

Abstract

Methods for the fermentative production of O-phosphoserine, cysteate, or taurine in microbes or unicellular organisms that contain a serB mutation that either decreases serB expression, reduces the amount of the serB gene product or results in a serB gene product with low enzymatic activity. Genetic modifications of the O-phosphoserine, cysteate, or taurine and/or substrate biosynthetic pathways in unicellular organisms that include bacteria, algae, microalgae, diatoms, yeast, or fungi are disclosed. Also disclosed are fermentation and processing methods for the production of various O-phosphoserine-, cysteate-, or taurine-containing products and the use of the cells, fermentation broth or extracts that contain O-phosphoserine, cysteate, or taurine to produce products for use in food, feed, beverages, dietary and health supplements, cosmetics, personal care, pharmaceuticals, agricultural production, or surfactants.
