Method for cultivating microorganisms

Abstract

The invention discloses a method for cultivating microorganisms. Microorganisms are introduced into a culture vessel with culture solution, and gas is introduced for cultivating. The culture vessel comprises a bubble guide component, a zigzag guide member and a guide plate of the bubble guide component provide bubbles with a zigzag upward march path, the introduced gas forms bubbles through a bubble generator, the bubbles enter from the bottom of the bubble guide component and climb upwards circuitously along the lower surface of the guide plate, and the bubbles and the culture solution with microorganisms change substance in climbing. The method for cultivating the microorganisms adopts the culture vessel comprising the bubble guide component of special structure, so that the contact area and the contact time of the bubbles and the culture solution in unit volume are effectively increased, the culture efficiency is improved, and the culture cost is reduced; and the design and assembly manner of the bubble guide component are flexible, the bubble guide component has strong adaptability, so that the method for cultivating microorganisms has good industrial application prospect.

Description

technical field [0001] The invention relates to the technical field of microorganism culture, in particular to a microorganism culture method. Background technique [0002] In the process of microbial cultivation, it is usually necessary to transfer gaseous nutrients from the atmosphere or artificial gas storage containers to the culture solution of microorganisms in the form of bubbles, especially photosynthetic microorganisms such as algae, which need to be in the presence of solar radiation and rich sources such as carbon dioxide. In the case of carbon-containing gas, growth and photosynthesis in a suitable nutrient culture medium, thus increasing the supply of gaseous nutrients in the microbial culture medium is beneficial to the growth of microorganisms. At present, there are three ways to increase the supply of gaseous nutrients: the first is to increase the gas transmission rate, and more gas is forced into the microbial culture environment within a certain period of ...

Problems solved by technology

The disadvantages of these three methods are: 1. all will increase the energy consumption of the microbial culture process, thereby increasing the production cost; 2. the mode of the microbial incubator cannot be enlarged to the scale of industrial production; ④ For microalgae cultivation, the existing technology can only provide carbon dioxide gas and light energy to a small number of microalgae cells for photosynthesis at the same time, which reduces the cultivation efficiency
