Abstract

PURPOSE:To enable the production of cacao-like oil or fat, by culturing a specific microbial strain in a medium containing a carbohydrate as a carbon source. CONSTITUTION:A microbial strain belonging to Mortierella genus and selected from Mortierella vinacea (IFO6738,7875), nana (IFO8794), ramaniana (IFO8184, 8185) and ramaniana var angulispora (IFO6744,8186,8187) is cultured in a medium containing a carbohydrate as a carbon source, and the objective oil or fat resembling cacao butter is separated from the cultured product. All of the above strains are molds stocked in the Fermentation Research Institute and registered in the IFO Catalogue. The carbohydrate used as the carbon source of the medium is e.g. glucose, molasses, etc., and the nitrogen source is e.g. NH4NO3, urea, etc. The cultivation is carried out preferably at 3.5-6.5pH, usually at 10-33 deg.C for 3-30 days.

The pH of the medium is preferably 3.5 to 6.5, usually 10 to 33°C.
Culture is performed for 3 to 30 days. Thus, an oil similar to cocoa butter is produced in the culture, and the oil is collected from the culture. When collecting fats and oils, since fats and oils are contained in the cells of filamentous fungi, it is preferable to separate the cells from the culture and collect the fats and oils from the cells. The oils and fats are collected according to conventional methods, such as by extraction with a solvent.

1 Erlenmeyer flask, each strain was inoculated, and cultured by shaking at a predetermined temperature and a predetermined period of 150 r:[)m. After culturing, the bacterial cells were collected by the mouth filtration method or centrifugation method. A part of it was accurately weighed to determine the moisture content, and placed in a constant temperature bath.
The cells were dried at 20°C for a day and night, the moisture content was determined, and the remaining bacterial cells were extracted for lipids. To extract lipids from the bacterial cells, add chloroform-methanol (2:IV) to the remaining wet bacterial cells.
/V) The mixture was added and homogenized in the presence of glass beads to simultaneously crush the bacterial cells and extract the lipids. In order to perform the extraction completely, this was repeated five times and all the extracts were collected. After the above-mentioned extract was purified by the partition washing method of li"olch, the solvent was distilled off under reduced pressure and the total lipid amount was measured by gravimetric method.The lipids were developed using Unicil as a packing material and chloroform and methanol. Separate oil and fat components (neutral lipids) and polar lipids by column chromatography using a solvent, measure the amount of oil and fats present, and
Gas chromatography was performed on the fat and oil components to determine the fatty acid composition. The amounts of oils (neutral lipids) produced by various types of Morteierella filamentous fungi and their fatty acid compositions determined by this method are shown in the following table.
