Gordona nitida and application of removing sulfur element from sulfur compound

Abstract

A Gordona nitida LSSEJ-1 (CGMCC No.0700) and its application in removing sulfur from the S-contained organic compound are disclosed. Said rod-shaped Gordona nitida LSSEJ-1 has 2-3 microns in length, shows positive to Gram staining, and contains meso diaminopimelic acid, characteristic arabinose and galactose, nocardomycolic acid and MK-9 (H2).

Description

field of invention The invention belongs to the field of biotechnology, in particular to a Gordonia and its application in removing sulfur from sulfur-containing compounds. Background technique Sulfur-containing organic compounds in petroleum include various mercaptans, thioethers, disulfides and thiophenes and their derivatives. Among them, the content of thiophene compounds is the most. Sulfur in petroleum products is released into the atmosphere in the form of sulfur dioxide through combustion, and then settles down in the form of acid rain, causing serious pollution to the environment and seriously threatening the global ecological balance. According to reports, the world's annual SO emissions into the atmosphere 2 Nearly 200 million tons, our country emits SO into the atmosphere every year 2 17.95 million tons, the area of ​​acid rain in my country is constantly expanding. In 1995, it has expanded to about 1 million square kilometers in central and southe...
