Deletion of the endogenous genes hdpA and ldh encoding dihydroxyacetone phosphate phosphatase and lactate dehydrogenase, respectively, prevented formation of glycerol and lactate as by-products and improved the yield to 0.343 mol/mol glucose.
Applying harvested runoff water through supplemental irrigation provides the twin benefits of alleviating the prevailing slack periods and improving the yields of smallholder farming systems.
Further technical improvements to drive down costs and improve the yield of the highest value products are, of course, still needed.
The factors that impact rigidity of PS microbeams including internal stress and stress gradient are still under investigation to understand and improve the yield.
Ultrasound has been shown to have desirable effects on both homogeneous and heterogeneous reactions, such as increasing the conversion, enhancing the selectivity, and improving the yield.
Some non-detergent sulfobetaines had been shown to prevent aggregation and improve the yield of active proteins when added to the buffer during in vitro protein renaturation.
The pretreatment not only enhance the bio-digestibility of the wastes for ethanol production, but also results in enrichment of the difficult biodegradable materials, and improves the yield of ethanol from the wastes.
This is consistent with the target of decreasing the content of olefins in gasoline and improving the yield of propylene with the second-stage riser reactor in the TMP process.
In order to optimize the procedure and improve the yield, a modified synthesis of 1l-1,2 3,4-di-O-cyclohexylidene-5-O-methyl-chiro-inositol, 1l-1,2 3,4-di-O-cyclohexylidene-5-O-methyl-chiro-inositolomplished by Barrs et al. [59].
These small molecules can improve the folding rate of the model substrate ribonuclease A by a factor of over 10 and improve the yield by up to a factor of 3 over traditional conditions.
