Genetic modification of the MET10 polypeptide eliminates hydrogen sulfide production, removing copper fining costs and odor defects.
- Lecithin Treatment Inhibits Melanoidin Formation in Yeast Propagation
Adding a lecithin treatment composition to molasses inhibits melanoidin formation, reducing evaporator fouling and water consumption.
- Semi-biosynthetic Fatty Alcohol Production via Recombinant Microorganisms
Recombinant microorganisms produce unsaturated lipid moieties to lower production costs for insect pheromones.
- Oleaginous Yeast Culture Medium Calcium Phosphate Ratio
Controlling the phosphate to calcium ratio below 675 prevents calcium binding inhibition, enabling high lipid yields from short chain fatty acids.
- Microbial Inoculant for High Lignin Plant Material Recycling
A microbial inoculant breaks down lignin in plant waste to release bioavailable nutrients.
- Norcoclaurine Synthase Mutations for Heterologous Production
Site-specific mutations in norcoclaurine synthase increase catalytic activity, resolving low enzyme efficiency in heterologous host cells.
