Embodiment 1

[0011] Example 1: Refining Wastewater Treatment Liquid Microbial Inoculant Preserved at Room Temperature

[0012] The liquid microbial agent for oil refinery wastewater treatment refers to the patent "A microbial agent for oil refinery wastewater treatment, its preparation method and its application" (Patent No.: ZL 200410081504.7) by fermentation and cultivation into a liquid microbial agent, and then the preservation of different bacterial agents The components of the agent were formulated into mother liquors of different concentrations, added to the liquid bacterial agent according to the formula content, and stored at room temperature. The MPN method (maximum probable number method) was used to count the viable bacteria of the bacterial agent at different storage stages, and the preservation process was investigated. The status of medium-contaminated bacteria and the treatment effect on oil refinery wastewater.

Embodiment 3

[0030] Embodiment 3: room temperature preserves aniline degrading functional bacterial agent

[0031] Taking the patented strain AN-P1 high-efficiency aniline-degrading bacteria (strain preservation number: CGMCC No.2783) as the research object, aniline-containing inorganic salt medium (Na 2 HPO 4 2g, KH 2 PO 4 0.5g, MgSO 4 ·7H 2 O 0.3 g, trace element solution 5mL, aniline 1g, 1000ml distilled water, pH 7.0), refer to the invention patent "A high-efficiency aniline-degrading bacteria and its use and use method" (patent application number: 200910058557.x) fermentation expansion Cultivate into bacterial liquid, centrifuge at 5000rpm and suspend with inorganic salt medium to make ready-to-use bacterial liquid (OD.600 is 1.0). The numbers are No. 1 and No. 2, and the recipe saved in No. 1 is 0.17‰C 6 h 8 o 6 +0.025‰CuSO 4 +10‰glycerin; No. 2 preservation formula is 0.4‰Na 2 S 2 o 4 +0.2‰NaHCO 3 +2‰aniline+10‰glycerol (glycerol is volume percentage, the rest is m...

Abstract

The invention belongs to the technical field of environmental protection, which specifically relates to an environmental microbial agent preservative, comprising a deoxidizing agent, an inhibitor and a preservative. The deoxidizing agent consists of ascorbic acid with copper sulfate or sodium thiosulfate with sodium bicarbonate. The inhibitor consists of copper sulfate or sodium benzoate or target characteristic pollutants. The preservative consists of glycerol. The preservative of the invention has the advantages of high economic efficiency, convenient use, long storage time, stable microbial agent performance after storage, lasting strain vigor and no secondary pollution and the like.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to a method for storing viable bacteria in microbial agents (i.e., environmental microbial agents) used for environmental pollution control and protection at room temperature, so as to achieve long-term and low-cost preservation and maintenance of microbial agents The purpose of improving the number of viable bacteria and the performance of pollution purification is to realize its commercialization and industrialization. Background technique [0002] At present, my country's environmental pollution is still very serious, and various pollution control processes and methods have emerged one after another, among which biological treatment methods are the mainstream technical means. In recent years, the number of microbial agents developed for the purpose of ecological environment protection and pollution prevention The use of additives can not only greatly s...
