摘要:
The present invention relates to a miniemulsion which comprises at least one hydrolase, where the continuous phase of the miniemulsion contains at least one oxidant, while the disperse phase comprises at least one C 6-60 -carboxylic acid and optionally at least one reactant. Furthermore, the present invention relates to a method of preparing the miniemulsion and to a process for the preparation of C 6-60 -percarboxylic acids and to a process for the preparation of an oxidized reactant, in each case using the abovementioned miniemulsions.
摘要:
Coordinately regulated over-expression of the genes encoding glucose 6-phosphate dehydrogenase ["G6PDH"] and 6-phospho-gluconolactonase ["6PGL"] in transgenic strains of the oleaginous yeast, Yarrowia lipolytica , comprising a functional polyunsaturated fatty acid ["PUFA"] biosynthetic pathway, resulted in increased production of PUFAs and increased total lipid content in the Yarrowia cells. This is achieved by increased cellular availability of the reduced form of nicotinamide adenine dinucleotide phosphate ["NADPH"], an important reducing equivalent for reductive biosynthetic reactions, within the transgenic microorganism.
摘要:
The present invention relates to a method of producing high-quality reduced coenzyme Q 10 converted from oxidized coenzyme Q 10 by natural reductase. It is stable, completely natural, and can be used for injection. This method is suitable for large-scale industrial production without special protective environment/atmosphere. The method of producing reduced coenzyme Q 10 includes three stages: (1) phosphorylation of oxidized coenzyme Q 10 ; (2) reduction of phosphorylated oxidized coenzyme Q 10 by biological reductases; (3) extracting reduced coenzyme Q 10 from reductases,
摘要:
The invention relates to a method for the economic, high-quality production of the co-enzyme Q10 with a higher yield, wherein phototrophic microorganisms are cultivated in a culture medium in a bioreactor under standard conditions and the growth of the phototrophic microorganisms has an exponential and a stationary growth phase. The method comprises the following steps: (a) induction of oxidative stress by the co-incubation of stress-induced substances and/or the increase of the surface irradiation intensity in the bioreactor and/or (b) addition of oleate to the culture medium.
摘要:
The present invention relates to the production of variants of lactic bacteria stems that produce, under standard fermentation conditions, at least about 1.2 times more K2 vitamin than the starting lactic bacteria stems cultured in the same conditions. The invention further relates to a method for preparing food products, including fermented products and/or fresh diary products, enriched with K2 vitamin, and to the food products thus obtained.
摘要:
A process for efficiently producing coenzyme Q10 by using a microorganism with the use of a coenzyme Q10 side chain synthase gene originating in a fungus belonging to the genus Rodotorula. A DNA having a DNA sequence represented by SEQ ID NO:1, 3 or 5 or a DNA sequence derived therefrom by deletion, addition, insertion and/or substitution of one or several bases and encoding a protein having a decaprenyl diphosphate synthase activity.
