Abstract

The invention relates to a method for promoting the quick proliferation of Botryococcus braunii, belonging to the technical field of microbe. In the method, trace elements are added in the conventional culture medium of Botryococcus; and the culture conditions are as follows: the culture temperature is 25+ / -5 DEG C; a fluorescent lamp is used as a light source, the light intensity is 80-120mu mol.m<-2>.s<-1>, and continuous illumination is adopted. The trace elements are metal ions of vanadium, tungsten, cerium and bismuth or a mixture thereof. By adopting the method that the metal ions of vanadium, tungsten, cerium, bismuth and the like are added in the culture medium of Botryococcus, the quick proliferation of microalgae can be significantly promoted, higher biomass can be obtained within unit volume and unit time and the yield of Botryococcus can be increased. A feasible technology is provided for the microalgae biofuel industrialization.

Description

technical field

[0001] The invention relates to a method for promoting the rapid proliferation of microalgae, in particular to adding a catalyst capable of promoting the rapid proliferation of hydrocarbon-producing botrytis into a conventional culture medium, and belongs to the technical field of microorganisms. Background technique

[0002] Brown Botrytis ( Botryococcus braunii ), also known as Conglomerate, its hydrocarbon content usually accounts for 15%-76% of the dry weight of algae biomass, which is much higher than that of other microorganisms. The composition and structure of the hydrocarbons produced by botrytis are very similar to petroleum, and it is expected to become a renewable and non-polluting alternative energy source for petroleum.

[0003] Botrytis mainly obtains the main nutrient elements (N, P) and some basic trace metal elements from the aqueous solution and air in which it grows. At present, there are many kinds of medium for grape algae. Chu10 mediu...
