USE OF PROBIOTIC YEAST CELLS PRODUCING RECOMBINANT PARATHORMONE FOR THERAPEUTIC PURPOSES
This invention relates to the use of probiotic yeast cells that produce recombinant parathormone for therapeutic purposes, where probiotic cells that produce rhPTH developed for use in hypoparathyroidism treatment are first microencapsulated, placed into gelatin capsules and then orally administrated.
ENZYME ENGINEERING TO ALTER THE FUNCTIONAL REPERTOIRE OF CANNABINOID SYNTHASES
Described herein are variant, novel cannabinoid synthases, nucleic acids encoding same, and various uses thereof. In one aspect, a variant cannabinoid synthase or an active fragment thereof is provided comprising a non-naturally occurring amino acid sequence relative to a wild-type cannabinoid synthase or an active fragment thereof which acts on a substrate to produce an altered amount of a cannabinoid relative to an amount of the cannabinoid produced by the wild-type cannabinoid synthase or active fragment thereof.
CO-PRODUCTION PATHWAY FOR 3-HPA AND ACETYL-COA DERIVATIVES FROM MALONATE SEMIALDEHYDE
The present disclosure provides methods for utilizing genetically modified microbes to co-produce 3-hydroxypropionic acid (3-HP) and acetyl-CoA, and derivatives thereof from malonate semialdehyde as a common single intermediate. The disclosure further provides modified microbe that co-produce the 3-HP and acetyl-CoA derivatives from malonate semialdehyde.
METHOD FOR PREPARING CULTURES OF LACTIC ACID BACTERIA
Microbial starter cultures. More specifically, a method for preparing a microbial culture such as a lactic acid bacteria (LAB) starter culture wherein at least one microbial strain such as a lactic acid bacteria and at least one inactivated yeast strain is inoculated in a culture medium.
YEAST STAGE TANK INCORPORATED FERMENTATION SYSTEM AND METHOD
Methods of and system for growing and maintaining an optimized/ideal active yeast solution in the yeast tank and fermenter tank during the fermentation filling cycle are provided. A new yeast stage tank is used between the yeast tank and the fermenter tank allowing yeast to rapidly produce a huge amount of active young yeast cells for a fermenter during the filling period. A measurable and useful controlling factor, % DT/% Yeast by weight ratio (or “food” to yeast ratio), is used (e.g., % DT=glucose), which offers information on the health status of the yeast. The controlling factor is used to control the status of the yeast throughout the entire process.
SYSTEM AND METHOD FOR INCREASED ALCOHOL TOLERANCE AND PRODUCTION IN YEAST
A method for producing metabolites that are heavy alcohols, and particularly branched-chain alcohols is provided, involving contacting a suitable substrate with recombinant microorganisms. The microorganisms contain at least one deletion, disruptions, or mutations from the GLN gene family, VPS gene family, GNP gene family, AVT gene family, GCN gene family, or YDR391C, and combinations thereof, and overproduce the heavy alcohol as compared to a wild-type yeast strain.
PROBIOTIC BACTERIA FOR YEAST BIOETHANOL PRODUCTION
The present invention is directed to compositions comprising hydrolase-secreting bacteria and fermenting microorganisms and use thereof, such as for fermentative production of ethanol.
CONSTRUCTION OF RECOMBINANT SACCHAROMYCES CEREVISIAE FOR SYNTHESIZING CARMINIC ACID AND APPLICATION THEREOF
The disclosure discloses construction of recombinant Saccharomyces cerevisiae for synthesizing carminic acid and application thereof and belongs to the technical field of genetic engineering and bioengineering. The disclosure obtains recombinant S. cerevisiae CA-B2 capable of synthesizing carminic acid by heterologously expressing cyclase Zhul, aromatase ZhuJ, OKS of Octaketide synthase 1, C-glucosyltransferase UGT2, monooxygenase aptC and 4′-phosphopantetheinyl transferase npgA in S. cerevisiae. The recombinant S. cerevisiae can be used for synthesizing carminic acid by taking self-synthesized acetyl-CoA and malonyl-CoA as a precursor. On this basis, OKS, cyclase, aromatase, C-glucosyltransferase and monooxygenase relevant to carminic acid are integrated to a high copy site, which can remarkably improve the yield of carminic acid. The yield of carminic acid can be increased to 2664.6 .Math.g/L by optimizing fermentation conditions, and the fermentation time is shortened significantly. Therefore, the recombinant S. cerevisiae plays an important role in the fields of cosmetics, textiles and food.
Yeast for ethanol production
Described herein are Saccharomyces cerevisiae strains MBG5038 and MBG5012 deposited under the Budapest Treaty and having accession Nos. NRRL Y67549 and NRRL Y67700, respectively, or a derivatives of strains NRRL Y67549 or Y67700 which exhibit one or more properties or defining characteristics of Saccharomyces cerevisiae strains MBG5038 or MBG5012. Also described are compositions comprising the Saccharomyces yeast and naturally occurring and/or non-naturally occurring components, as well as are processes for producing ethanol from starch-containing material using the strains.
Freeze-resistant yeast and uses thereof
Freeze-resistant baker's yeast (Saccharomyces cerevisiae) strains and uses thereof. For example, for the preparation of fresh or frozen dough products, e.g., bread. The freeze-resistant baker's yeast strains, which are, e.g., obtainable from specific deposited strains, e.g., by breeding these strains with each other or with other Saccharomyces cerevisiae strains. Methods of using said strains or methods of preparing a dough or a dough product or a yeast product are also provided.
