Abstract

The invention relates to an Aureobasidium pullulans strain and an application thereof, and belongs to the technical fields of fermentation engineering and biology. The preservation name of the Aureobasidium pullulans strain is Aureobasidium pullulans ZK-502, the strain is preserved in CGMCC (China General Microbiological Culture Collection Center) on August 20, 2018 at No.3 of No.1 West Beichen Road, Chaoyang District, Beijing, and the preservation number is CGMCC No. 16326. The Aureobasidium pullulans strain can efficiently produce liamocin by fermentation and produces no melanin, fermentation broth is light pink to faint yellow, and follow-up treatment process can be simplified. The method is simple and feasible, raw materials are simple in composition, yield of liamocin can reach 8-10 g / L, and commercial and large-scale production of liamocin is expected to be realized; the obtained liamocin product is dissoluble in water and has wide application prospect in medicine, cosmetics andfood.

Description

technical field

[0001] The invention relates to an Aureobasidium pullulans strain and an application thereof, belonging to the fields of fermentation engineering and biotechnology. Background technique

[0002] Liamocin is one of the new active products of Aureobasidium pullulans. Because its density is heavier than water, it will settle at the bottom when it is still, so it is also called heavy oil. Liamocin currently generally refers to a class of polyol ester compounds that are heavier than water produced by Aureobasidium pullulans. The head group of the polyol ester is mostly mannitol or arabic alcohol, and the tail is a triplet of 3,5-dihydroxydecanoic acid. body or quadruple.

[0003] Liamocin has a coconut aroma and is denser than water. The color of the oil varies from light yellow to malachite, and most of the oil is fluorescent. It is slightly soluble in water and easily soluble in organic solvents. It has been proved that the polyol ester has various biological ...
