摘要:
The invention relates to recombinant expression of a variant form of a fungal C1 strain β-glucosidase. The invention also relates to the generation of fermentable sugars from biomass and the production of biofuels by fermentation of the sugars using genetically modified organisms expressing the β-glucosidase variant. The invention provides methods for producing a fermentable sugar, such as glucose, from cellobiose by contacting cellobiose with a recombinant β-glucosidase variant protein, such as a variant protein secreted by a recombinant host cell into culture medium. Methods of the invention may be used for conversion of a biomass substrate to a fermentable sugar, and ultimately to ethanol or other biofuel.

This present disclosure relates to methods for improved production of proteins from a cell culture, particularly to culture components and conditions that can preferentially increase the expression of proteins produced from genes under the control of xylanase gene promoter sequences. The improved methods can be used for the production of enzyme compositions with enhanced xylanase and hemicellulolytic activity.

Methods for increasing yield of fermentable sugars from plant stover are provided. The methods include using plants homozygous for two brown midrib mutations, bm1 and bm3. The methods also include using plants homozygous for a mutation in a gene that results in reduced cinnamyl alcohol dehydrogenase activity, and a mutation in a gene that results in reduced 5-hydroxyconiferaldehyde/5-hydroxyconiferyl alcohol O-methyltransferase activity. The methods also include using transgenic plants that have reduced cinnamyl alcohol dehydrogenase activity and reduced 5-hydroxyconiferaldehyde/5-hydroxyconiferyl alcohol O-methyltransferase activity in comparison with wild-type plants.
摘要:
Methods for producing quadrivalent meningococcal meningitis polysaccharide and conjugate vaccines for serotypes A, C, Y and W-135 disclosed. Neisseria meningitidis fastidious medium was designed to maximize the yield of capsular polysaccharides and generate minimal cellular biomass and endotoxin in a short duration of fermentation. The crude polysaccharides are isolated, purified, and mechanically depolymerized by sonication. These purified polysaccharides were found in human clinical trials to be safe and immunogenic against meningococcal disease caused by N. meningitidis A, C, Y and W-135 serogroups in sub-Saharan Africa. In the preferred embodiment, the polysaccharides are conjugated to carrier proteins of diphtheria or tetanus toxiod to an average molecular size of 5100 to 9900 Daltons and provide broad spectrum protection to humans of all ages. Accelerated polysaccharide production and the efficacy of the resulting vaccine are demonstrated.
