Abstract

The invention provides a Rhodotorulasp.2-14 China general microbiological culture collection (CGMCC) NO. 4445. The Rhodotorulasp.2-14 is circular or oval, the size of the Rhodotorulasp.2-14 is 4.5-5.1*6.3-7.2mu m, and the reproduction mode is budding and is free of the formation of pseudohypha, ascospore and ballistospore. The invention further discloses a method for producing trehalose using the Rhodotorulasp.2-14. The trehalose of a bacterial strain is high in yield, simple in a culture medium and cultivation process, and energy-saving and environment-friendly in extraction process. The method for producing the trehalose has the advantages of being simple and practical, and low in cost, thereby being easy to popularize and apply in the industrial production.

Description

technical field

[0001] The present invention relates to a microorganism, especially Rhodotorula 2-14 ( Rhodotorula sp. 2-14) CGMCC NO. 4445 (preserved in CGMCC, General Microorganism Center of China Microbiological Culture Collection Management Committee on December 8, 2010, and the preservation number is CGMCC No. 4445); the present invention also relates to the use of this bacterial strain to produce seaweed sugar method. Background technique

[0002] Trehalose is composed of two molecules of glucopyranose monomers connected by α-1,1 glycosidic bonds, its chemical name is α-D-glucopyranosyl-α-D-glucopyranoside, and its molecular formula is C 12 h 22 o 11 2H 2 O, relative molecular weight is 378.33 (containing two molecules of crystal water), specific rotation [α] D =+178°(20°C), the melting point is 97°C, and it will lose crystal water when heated. Because of its symmetrical molecular structure and no hemiacetal group, it has neither reduction nor mutarotation. Its ...
