Embodiment 1

[0030] Example 1 Isolation and screening of Candida glabrata (Candida glabrata) CY-9

[0031] The separation process of Candida glabrata (Candida glabrata) CY-9 of the present invention: take by weighing Suqian planting eggplant rhizosphere soil 10g, add 90mL sterile water, obtain 10 -1 Dilution, in a shaker at 30°C at 130r / min, cultured for 2-3h, continued to add sterile water to dilute to obtain 10 -5 , 10 -6 , 10 -7 , 10 -8 200uL of the above dilutions were spread on the MRS solid plate, cultured at 30°C for 48 hours, and a single colony was picked and inoculated on the slant of the MRS solid medium for preservation.

[0032] The physiological activity characteristics of Candida glabrata (Candida glabrata) CY-9 are as follows:

[0033] a. Morphological characteristics: The colony on the MRS solid medium is white to off-white, with a smooth surface and no folds; the spores are unicellular, colorless, oval or oval. After adding CaCO 3 Dissolving circles can be produced ...

Embodiment 2

[0038] Example 2 Preparation of biological treatment agent containing Candida glabrata and its application in kitchen waste

[0039] Preparation of biological treatment agent containing Candida glabrata:

[0040] (1) Cultivate Candida glabrata on MRS solid culture at 30°C for 24h; inoculate it in a shaker flask of fermentation liquid, vibrate at 30°C and 130r / min for 24h to form seed liquid;

[0041] The seed solution is inoculated into the culture material in the fermenter at a volume ratio of 1:400 for fermentation production. The basic working parameters of the fermenter are: temperature: 30-35°C, pH=6.2-6.6, stirring speed: 130r / min , dissolved oxygen: 30%, tank pressure: 0.04MPa; stop fermentation after 24 hours of fermentation, then centrifuge at 6000r / min for 10 minutes, take the sediment and dilute it with sterile water to make a bacterial agent; the concentration of viable bacteria in the bacterial agent is detected to be 4.6 ×10 9 CFU / mL;

[0042] (2) Sawdust, bra...

Embodiment 3

[0052] Example 3 Preparation of biological treatment agent containing Candida glabrata and its application in kitchen waste

[0053] This embodiment is basically the same as Example 2, except that in step (2), the mass ratio of sawdust, bran powder and rice husk is 7:2:3; in step (3), microbial inoculant and carrier The mass ratio is 1:11.

[0054] Weight loss efficiency test of biological treatment agent on food waste after treatment:

[0055] (1) The composition of kitchen waste: the food left in the canteen, remove the large and hard parts such as plastic or bones;

[0056] (2) The biological treatment agent prepared by the above method is applied to the treatment of kitchen waste: preheating operation 6h, ventilation and stirring at the same time; 10kg of food waste to be treated is added in the processor after the pre-operation, and biological treatment agent Mix for aerobic fermentation, and ventilate and stir at the same time; the amount of biological treatment agent ...

Abstract

The invention provides a kind of Candida glabrata, which is classified as Candida glabrata CY-9, and is preserved in the General Microbiology Center of China Microbiological Culture Collection Management Committee, and the address is Beichen West Road 1, Chaoyang District, Beijing No. 3 Institute of Microbiology, Chinese Academy of Sciences, Zip code 100101, deposit number: CGMCCNO.12449, deposit date is May 13, 2016. The invention also provides the application of the candida glabrata in the treatment of kitchen waste. The Candida glabrata has high activity of protease, amylase, and oil hydrolase, degrades glucose to produce acid, and is a thermophilic bacteria with high salt tolerance and acid resistance. Kitchen weight reduction reaches 85%.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to Candida glabrata, and also relates to the application of the Candida glabrata in the treatment of kitchen waste. Background technique [0002] Kitchen waste mainly comes from food scraps (kitchen waste) and food residues (swill) from catering operations and residents’ lives. There is a large amount of kitchen waste generated by families, schools, canteens and catering industries in my country. If it is not handled properly, it will pollute the environment, spread diseases, and endanger human health. Food waste has the characteristics of high water content (up to 80-95%), high salinity, high organic matter content, perishable odor and breeding of mosquitoes and flies. The main components are water, sugar, protein, fat, salt and oil, etc. . [0003] At present, the treatment methods of food waste are mainly divided into non-biological treatment (incineration, d...
