Latest Patents

Zhen Ya Zhang's latest patents focus on a method for producing vitamin B12 from hydrogen-metabolizing methane bacteria. The process involves acclimatizing mesophilic methane bacteria obtained from digested sludge in an H/CO medium. These bacteria are then grown on a support that includes inorganic nutritional salts of trace metal elements using an immobilized bed bioreactor. The bacteria metabolize a mixed gas, which is prepared by adding hydrogen to either coal gas or biogas, converting it into methane. Concurrently, cobalamin contained in the fermented liquor is recovered as an extracellular product in the form of cyanocobalamin using potassium cyanide, thereby producing vitamin B12 efficiently in high content and yield.
