It includes the stages of grinding the lignocellulosic biomass to a size of 15-30 mm, subjecting the product obtained to steam explosion pre-treatment at a temperature of 190-230° C. for between 1 and 10 minutes in a reactor (2), collecting the pre-treated material in a cyclone (3) and separating the liquid and solid fractions by filtration in a filter press (9), introducing the solid fraction in a fermentation deposit (10), adding a cellulase at a concentration of 15 UFP per gram of cellulose and 12.6 International Units of β-glucosidase enzyme dissolved in citrate buffer pH 4.8, inoculating the fermentation deposit (10) with a culture of the heat-tolerant bacteria Kluyveromyces marxianus CECT 10875, obtained by chemical mutagenesis from strain DER-26 of Kluyveromyces marxianus and shaking the mixture for 72 hours at 42° C.

Walk-through mutagenesis and natural-variant combinatorial fibronectin Type III (FN3) polypeptide libraries are described, along with their method of construction and use. Also disclosed are a number of high binding affinity polypeptides selected by screening the libraries against a variety of selected antigens.

A minicell display method has been developed which has significant advantages for screening peptide libraries for candidates that can bind and effectively modulate a particular biological process. The method, based on the small, anucleate minicell, has increased versatility in generating unique sequences to screen as well as increasing the size of the peptides to be screened. In vivo mutagenesis, at the level of protein synthesis, as well as DNA replication, increases diversification of the library to be screened and therefore substantially increases the number of potential peptides that can modulate a particular biological response or mechanism.

The present invention relates to a new and distinctive canola cultivar, designated DN040845. Also included are seeds of canola cultivar DN040845, to the plants, or plant parts, of canola DN040845 and to methods for producing a canola plant produced by crossing the canola DN040845 with itself or another canola cultivar, and the creation of variants by mutagenesis or transformation of canola DN040845.

The invention relates to a new process for concentrating epothilones in culture media, a new process for the production of epothilones, a new process for separating epothilones A and B and a new strain obtained by mutagenesis for the production of epothilones, as well as aspects related thereto. New crystal forms of epothilone B are also described.

According to the invention, there are provided novel canola cultivars, seeds of canola cultivars, to the plants, or plant parts, of novel canola cultivars and to methods for producing a canola plants produced by crossing the novel canola cultivars with themselves or another canola cultivar, and the creation of variants by mutagenesis or transformation of the canola cultivars. The novel canola cultivar(s) include canola plants having a desired trait that includes an oleic acid value of about 70% and a yield greater than about 2100 kg/ha, and oils canola seeds having an oleic acid content of greater than about 70% and an α-linolenic acid value of less than about 3%.

The present invention relates to a new and distinctive canola cultivar, designated DN040244A. Also included are seeds of canola cultivar DN040244A, to the plants, or plant parts, of canola DN040244A and to methods for producing a canola plant produced by crossing the canola DN040244A with itself or another canola cultivar, and the creation of variants by mutagenesis or transformation of canola DN040244A.

The present invention relates to a new and distinctive canola, designated G2X0062A/B. Also included are seeds of canola G2X0062A/B, to the plants, or plant parts, of canola G2X0062A/B and to methods for producing a canola plant produced by crossing the canola G2X0062A/B with itself or another canola genotype, and the creation of variants by mutagenesis or transformation of canola G2X0062A/B.

The invention discloses a Grifola frondosa strain for producing polysaccharide with a composite raw material of rice bran and wheat bran, which belongs to the technical field of microbial application technology and food biology. The Grifola frondosa strain JSU10 is preserved in China general microbiological culture collection center (CGMCC) in October 8th, 2010 with the CGMCC No. 4179 and is identified to be Grifolasp. The invention improves the positive mutation rate of the Grifola frondosa strain for rapidly growing and producing Grifola frondosa polysaccharide on a composite culture medium of rice bran and wheat bran by composite mutagenesis of ultraviolet rays and microwave to obtain a high-yield strain; the strain and the original strain are respectively a liquid fermentation rice bran and wheat bran composite culture medium; and hypha dry weight and polysaccharide of the mutated strain are respectively improved by 39.24 percent and 42.58 percent compared with the original strain.
