Embodiment 1

[0035] After the coenzyme Q10 preserved strain CGMCCNo.4497 was activated for three generations, a single colony with a round and full appearance, smooth edges and darker color on the plate was picked and diluted and spread on the plate medium for culture. The plate medium components are: glucose 2g / L, yeast powder 1g / L, peptone 1g / L, agar powder 2g / L, pH 6.8, and the culture conditions are 32°C for 5 days, until the appearance of the colonies on the plate is round and the edges are smooth , When the color is darker, it can be inserted into the mother bottle for cultivation.

[0036] Mother bottle medium components are: ammonium chloride 1.7g / L, peptone 0.7g / L, monosodium glutamate 0.4g / L, corn steep liquor 0.4g / L, glucose 2g / L, disodium hydrogen phosphate 0.35g / L, phosphoric acid Sodium dihydrogen 0.35g / L, ferric chloride 0.08g / L, magnesium sulfate 1.4g / L, potassium chloride 1.4g / L, copper sulfate 0.02g / L, zinc chloride 0.0006g / L, calcium bicarbonate 5.6g / L, auxiliary liquid...

Abstract

The invention provides a coenzyme Q10 fermentation process and a control strategy. Rhodobacter sphaeroides fermentation is adopted to produce coenzyme Q10, a specific operation method of coenzyme Q10 fermentation is provided, a process regulation and control standard is created, through bacterial type change in observation of the fermentation process, the bacterial type transition period is taken as a basis for judging time and amplitude for process parameter adjustment, the fermentation level of the coenzyme Q10 is greatly improved, the production level is stabilized, and the fermentation cost is reduced.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a coenzyme Q10 fermentation process and control strategy. Background technique [0002] Coenzyme Q10 is combined on the mitochondrial membrane in the cells of animals, plants and microorganisms. It is an important hydrogen transporter in the respiratory chain, an effective biochemical drug, and has many important physiological functions. A number of data prove that coenzyme Q10 is becoming more and more important to human health and disease treatment. Recent studies have found that coenzyme Q10 has anti-aging effects, and it has been widely used in the field of cosmetics and health products, and the demand at home and abroad has further expanded. [0003] The production methods of coenzyme Q10 mainly include animal and plant tissue extraction, chemical synthesis and microbial fermentation. Among them, the cost of animal and plant extraction is too high and is not suitable f...
