Abstract:
PROBLEM TO BE SOLVED: To provide a method for proliferating eukaryotic microorganisms which can produce lipids, in particular lipids containing polyenoic fatty acids, and a method for producing lipids of the eukaryotic microorganisms.SOLUTION: There are provided the method for proliferating eukaryotic microorganisms capable of producing at least about 20% of eukaryotic microorganism biomass as lipids, and the method for producing lipids of the same. The lipids preferably contain one or more polyenoic fatty acids, and a carbon source, preferably a non-alcohol carbon source, and restricted nutrient sources are added to a fermentation medium containing the eukaryotic microorganisms. The carbon source and the restricted nutrient sources are preferably added at a sufficient rate to increase biomass density of the fermentation medium at least at about 100 g/L.

PROBLEM TO BE SOLVED: To provide a process for growing eukaryotic microorganisms which are capable of producing lipids, in particular lipids containing polyenoic fatty acids, and to provide a process for producing eukaryotic microbial lipids.SOLUTION: The present invention provides a process for growing eukaryotic microorganisms which are capable of producing at least about 20% of their biomass as lipids and a method for producing the lipids. Preferably the lipids contain one or more polyenoic fatty acids. The process comprises adding to a fermentation medium comprising eukaryotic microorganisms a carbon source, preferably a non-alcoholic carbon source, and a limited nutrient source. Preferably, the carbon source and the limited nutrient source are added at a rate sufficient to increase the biomass density of the fermentation medium to at least about 100 g/L.
Abstract:
PROBLEM TO BE SOLVED: To economically produce arachidonic acid, and to provide a food formulated therewith. SOLUTION: Microorganisms of the genus Mortierella sect. schmuckeri are cultured in a fermentation medium preferably containing composite nitrogen source components. The arachidonic acid is a precursor of eicosanoid important as a nutriment for infants, and a mixed milk for infants and a baby food having the improved content of the arachidonic acid are produced by formulating the microorganisms of the genus Mortierella sect. schmuckeri or a lipid isolated from such microorganisms to food products.

Abstract:
PROBLEM TO BE SOLVED: To provide an effective method for preparation of substituted aryl lactic acid containing cyclodepsipeptides. SOLUTION: The invention relates to the new method for the preparation of substituted aryl lactic acid containing cyclodepsipeptides with 24 ring atoms, comprising addition of 4-nitrophnyl lactate to a main culture liquid of Mycelia sterilia, a fungal strain of the Agonomycetales class under an asceptic condition, continuing fermentation and extracting and purifying the culture, or adding substrates such as leucine, lactic acid, ATP, S-adenosyl-L-methionine, 4-nitrophenyl lactate, etc., to the enzymatic preparation isolated from the fungal strain to carry out an in vitro reaction.

Abstract:
An oligonucleotide probe is disclosed, the probe including an oligonucleotide, a fluorescer molecule attached to a first end of the oligonucleotide and a quencher molecule attached to the opposite end of the oligonucleotide. The probe is rendered impervious to digestion by the 5′→3′ exonuclease activity of a polymerase and the 5′→3′ extension of by a polymerase. The invention also includes methods for performing combined PCR amplification and hybridization probing, one such method including the steps of contacting a target nucleic acid sequence with PCR reagents and an oligonucleotide probe as described above, and subjecting these reagents to thermal cycling. One preferred refinement of the above method further includes the addition of a strand displacer to facilitate amplification. Additional similar combined PCR hybridization methods are disclosed, such methods not requiring probes having their 5′ ends protected, wherein (i) the polymerase lacks 5′→3′ exonuclease activity, (ii) a 5′→3′ exonuclease inhibitor is included, and (iii) an exonuclease deactivation step is performed.
Abstract:
Disclosed is a process for growing the microflora Thraustochytrium, Schizochytrium, and mixtures thereof, which includes the growing of the microflora in fermentation medium containing non-chloride containing sodium salts, in particular sodium sulfate. In a preferred embodiment of the present invention, the process produces microflora having a cell aggregate size useful for the production of food products for use in aquaculture. Further disclosed is a food product which includes Thraustochytrium, Schizochytrium, and mixtures thereof, and a component selected from flaxseed, rapeseed, soybean and avocado meal. Such a food product includes a balance of long chain and short chain omega-3 highly unsaturated fatty acids.
