The present invention relates to the field of bio-production of chondroitin. There is a need in the art for chondroitin production methods allowing its highly efficient synthesis and secretion. The solution proposed in the present invention is the use of a recombinant cell, in particular a recombinant yeast, comprising many modifications as described in the present text. The present invention further proposes methods allowing the bio-production of chondroitin using the recombinant cell, in particular a recombinant yeast, of the invention.

A microorganism of the genus Gluconacetobacter has enhanced cellulose productivity due to overexpression of fructose-bisphosphate aldolase, and optionally, phosphoglucomutase, UTP-glucose-1-phosphate uridylyltransferase, or cellulose synthase. A method of producing cellulose and a method of producing the microorganism are provided.

Alzheimer's disease (AD) is the most common type of dementia in aging adults with the number of people living with AD projected to increase, making the search for treatments and tools to diagnose and measure disease progression increasingly urgent. In particular, ideal biomarkers for diagnosis of AD should not only have high specificity for disease versus non-disease and high sensitivity for distinguishing between disease types but also should be able to detect changes at a very early stage of the disease. Using microglia activation as an early event of AD's onset, the present inventors have identified a panel of biomarkers in CSF which has the potential to diagnose, stage and determine the likelihood of developing AD.

An inositol preparation method by enzymatic catalysis uses starch and cellulose or substrates thereof as substrates. Raw materials are converted to inositol by in vitro multi-enzyme reaction system in one pot. The yield from the substrate to inositol is significantly improved by process optimization and adding new enzymes. The new enzymes can promote the phosphorolysis of starch or cellulose and utilization of glucose, which is the final production after the phosphorolysis of starch and cellulose. The inositol preparation method described herein has great potentials in industrial production of inositol because of high inositol yield, easy scale-up, low production cost, and lower impact to environment

Mammalian milk oligosaccharides (MMO) are produced in plants engineered to express recombinant MMO biosynthetic pathways.

The present application relates to a psicose-6-phosphate phosphatase comprising motif A and motif B, a composition for producing D-psicose comprising the enzyme, and a method for producing D-psicose using the enzyme.

Disclosed herein are methods of producing hexoses from saccharides by improved enzymatic processes. The improved processes utilize enzymes with higher activities than those previously reported to convert starch or a starch derivative, cellulose or a cellulose derivative, or sucrose to a glucose 6-phosphate (G6P) intermediate.

The present disclosure generally relates to modified microorganisms comprising an optimized system for oligosaccharide utilization comprising one or more polynucleotides coding for one or more energy independent oligosaccharide transporters for transporting an oligosaccharide into the microorganism, one or more polynucleotides coding for enzymes that catalyze the conversion of the oligosaccharide into at least one phosphorylated saccharide, and one or more polynucleotides coding for enzymes that catalyze the conversion of the phosphorylated saccharide into an isomer of the phosphorylated saccharide that is utilized in one or more enzymatic pathways in the microorganism for the production of an organic molecule such as acetic acid, acrylic acid, 3-hydroxypropionic acid, lactic acid, etc. The present disclosure also generally relates to methods of using the optimized system for oligosaccharide utilization.

The present invention relates to genetically engineered organisms, especially microorganisms such as bacteria and yeasts, for the production of added value bio-products such as specialty saccharide, activated saccharide, nucleoside, glycoside, glycolipid or glycoprotein. More specifically, the present invention relates to host cells that are metabolically engineered so that they can produce said valuable specialty products in large quantities and at a high rate by bypassing classical technical problems that occur in biocatalytical or fermentative production processes.

Provided is a recombinant polynucleotide including a promoter region derived from an acetic acid-producing bacterium and a polynucleotide sequence encoding a target protein operably linked to the promoter, a host cell including the same, and a method of expressing a target gene or protein using the host cell.
