Embodiment 1

[0010] 1. Collection of strain GW61

[0011] In September 2019, a strain was isolated from corn collected in Xianyang City, Shaanxi Province, named strain GW61.

[0012] 2. Identification of strain GW61

[0013] See sequence 1 (SEQ ID NO.1) of the sequence listing for the BT partial sequence of the strain GW61, which has the highest sequence similarity with GENBANKACCESSIONNO.JN854007.1, with a similarity of 99.5%.

[0014] According to the above identification results, the strain GW61 belongs to Alternaria sp.

[0015] 3. Preservation of strain GW61

[0016] Strain GW61, belonging to Alternaria sp, was November 27, 2020 Preserved in the General Microorganism Center of China Committee for the Collection of Microbial Cultures (CGMCC for short, address: No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing), the registration number of the preservation center is CGMCC No.21070 .

[0017] 4. Production of alternariol by strain GW61

[0018] 1) Take the bacterial str...

Abstract

The invention discloses an Alternaria sp strain GW61 CGMCC No. 21070 and application thereof in preparing Alternaria phenol. The strain is preserved in China General Microbiological Culture Collection Center (CGMCC for short, address: #3, No. 1 Yard, West Beichen Road, Chaoyang District, Beijing) as a patent strain on November 27, 2020, and the registration number of the strain in the preservation center is CGMCC No. 21070. The strain effectively solves the technical problem in the industry of preparing high-purity Alternaria phenol standard products.

Description

technical field [0001] The invention relates to the technical field of alternaria producing alternariol. Background technique [0002] Alternaria sp. is widely distributed in vegetables, fruits, grains and other agricultural products. In the production and transportation of agricultural products, polluted Alternaria can produce a variety of Alternaria toxins, mainly including Alternariol, Alternarinic Acid, Alternaritoxin I, II, III, Tentoxin Wait. Alternaria mycotoxins are highly toxic to reproductive and developmental systems and pose teratogenic and carcinogenic risks. Among them, alternariol can induce fetal esophageal squamous cell carcinoma. Although a lot of research has been done on the toxicity of alternariol to animals, there are still no relevant policies and official regulations on the limit standards for food and feed, so the development of technology for the development of standards for this toxin is relatively slow. How to prepare high-purity alternariol s...
