Description

Device and method for improving gibberellin fermentation by using vegetable oil

Technical Field

The invention relates to the field of microorganisms, in particular to a device and a method for improving gibberellin fermentation by using vegetable oil.

Background

Gibberellin is used as a high-efficiency broad-spectrum plant growth hormone and has wide application in agriculture and forestry production and beer fermentation processes. With the popularization of hybrid rice seed production technology and the continuous expansion of fruit and vegetable planting industry, the commercial demand of gibberellin is also increased, but the higher selling price of gibberellin limits the further use of gibberellin. At present, GA3 is one of the most widely used plant growth hormones, and with the intensive research and market differentiation demands, the homologs GA4 and GA7 are more and more valued. Aiming at the problem that no production strains for high-yield GA4 are obtained in China at present, the production strains are limited by a fermentation process, the produced mixture is GA4+7, the content of GA7 is generally more than 30%, and the GA4+7 mixture 16 is limited in agricultural production application, because the functions of promoting flower bud differentiation, preventing fruit rust and fruit cracking and the like of GA4 are weakened by the contained GA7, a high-content GA4 product is urgently needed in the market.

Dissolved oxygen also plays a great role in microbial metabolism, affecting the cell reducing power NADPH and energy metabolism. Oxygen is consumed in the growth of the gibberella granatum and the synthesis process of gibberellin, and because a large number of oxidation reactions are involved in the biosynthesis pathway of gibberellin, such as the reactions involved by dehydrogenase, dioxygenase and P450 monooxygenase, oxygen is consumed, so that sufficient dissolved oxygen is necessary in the production process of gibberellin. In the actual production of gibberellin, dissolved oxygen control is generally achieved by increasing the rotation speed, increasing the ventilation amount, supplementing water, reducing the temperature, adding an oxygen carrier, a surfactant and the like. During the fermentation process, the yield of gibberellin is reduced due to too high dissolved oxygen, too fast thallus growth, large amount of byproducts and the like.

At present, the dissolved oxygen is too low in the fermentation process, so that the metabolic process in mycelium is often changed, for example, anaerobic respiration can generate a large amount of ethanol, acetic acid and the like, and the cells are poisoned; on the other hand, the pH value is reduced, the mycelium autolysis, the fermentation is stopped, and the titer is lower. Therefore, in the fermentation process of producing gibberellin by using the gibberella bardii, sufficient dissolved oxygen is of great importance, and the addition of vegetable oil is inconvenient in the traditional mode. In view of this, the present invention provides an apparatus and method for improving gibberellin fermentation using vegetable oil.
