Application of rhodococcus erythropolis in cleaning heavy oil dirt

Abstract

The invention discloses a novel function of Rhodococcus erythropolis in cleaning of heavy oil scales, wherein, heavy oil biological cleaning agent can be prepared by utilization of thallus cells generated by the Rhodococcus erythropolis for preparation of bacterial solution with water. Particularly, the heavy oil biological cleaning agent consists of thallus cells XP which are cultured by Rhodococcus erythropolis strain CCTCC M 205068 and water, wherein, the dry weight concentration of the Rhodococcus erythropolis thallus cells XP is 8 to 20 grams per liter and the optimized concentration is 12 to 15 grams per liter. Compared with the prior art, the novel function of the Rhodococcus erythropolis in the cleaning of the heavy oil scales has the advantages of good use effect, strong degreasing ability, small environmental pollution and so on, can clean the heavy oil scales on surfaces of metals, plastics, glass and so on and can be widely used for cleaning work platforms, machinery equipment, components and parts, containers and pipes in crude oil mining and production places.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a new application of Rhodococcus erythropolis known to have the function of desulfurizing crude oil in cleaning heavy oil dirt. Background technique [0002] Rhodococcus erythropolis (Rhodococcus erythropolis) CCTCC M 205068 is a strain with crude oil desulfurization function screened out by the inventor in the early years. The strain was preserved in the China Center for Type Culture Collection (Address: Wuhan, Hubei Province, China) on June 20, 2005. Wuhan University, postal code 430072), Chinese patent 200510044599.X obtained the patent protection of the strain, and described in detail the screening of the strain, the cultivation of the strain and the acquisition and use of the bacterial liquid. The research and utilization of this strain in previous patents and literatures only stayed in its desulfurization of crude oil, and did not find its other functions. [0003] In the fie...

Problems solved by technology

Chinese patent application 200610013444.4 discloses a heavy oil cleaning agent, which consists of tetrasodium edetate 1-5; sodium nitrite 0.1-1; sodium carbonate 0.5-2; fatty alcohol polyoxyethylene ether 2-10; Fatty alcohol polyoxyethylene ether sodium sulfate 1-5; triethanolamine 0.2-1 and the rest of water, although it does not contain alkaline substances, but because it contains many kinds of inorganic salts and organic salts, it will remain in the waste after cleaning. The discharge in the liquid cannot be degraded in a short period of time, and there is still pollution to the environment, which cannot meet the high requirements of circular economy and environmental protection
