Abstract

The invention provides a strain of Chryseobacterium that efficiently degrades picolinic acid and its application, belonging to the technical field of bioengineering. The present invention isolates and screens a picolinic acid-degrading bacterium, Chryseobacterium sp., which is classified as Chryseobacterium sp. and is preserved in the General Microorganism Center of China Committee for the Collection of Microorganisms, with the preservation number CGMCC NO.10699. The advantage of the present invention is that this Chryseobacterium can effectively degrade picolinic acid under the condition that the pH value range is wider or the temperature range is wider, and the pH value range is wider and the temperature range is wider; The aerobic biological treatment of picolinic acid wastewater in a wide temperature range from weak base to weak acid has broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of bioengineering, and in particular relates to a strain of Chryseobacterium efficiently degrading picolinic acid and its application. Background technique

[0002] Picolinic acid and its derivatives are widely used in the production of medicines, pesticides and daily chemicals, and the widespread use of picolinic acid leads to environmental pollution. Picolinic acid wastewater can be treated by aerobic biological method. At present, the microbial resources for aerobic degradation of picolinic acid mainly include Arthrobacter, Mycobacterium and Streptomyces. There are few reports on strains of other genera.

[0003] The most important use of picolinic acid in industry is the production of medicines and pesticides. The resulting wastewater has a high acidity and a pH value between 4 and 6. Under strong acidic conditions, the growth of picolinic acid-degrading bacteria reported in the literature is signific...
