Embodiment 1

[0033] In this example, the hydrogen-producing microalgae is exactly the same as in Comparative Example 1, which is also Chlamydomonas reinhardtii. The process of using the Chlamydomonas reinhardtii to photolyze water to generate hydrogen is as follows:

[0034] 1) exactly the same as step 1) in Comparative Example 1;

[0035] 2) It is basically the same as step 2) in Comparative Example 1, except that the TAP-S hydrogen production medium of Chlamydomonas reinhardtii contains 0.3g·L -1 Glucose, the specific formula is as follows:

[0036] Chlamydomonas reinhardtii contains 0.3g·L -1 The formula of the TAP-S hydrogen production medium for glucose is: use water as the solvent, refer to the formula of the TAP medium, replace the corresponding sulfate in the medium with chloride, and add organic matter. The types and concentrations of the nutrients contained are as follows: Glucose 0.3g·L -1 , NH 4 Cl0.4g / L, K 2 HPO 4 0.108g / L, KH 2 PO 4 0.108g / L, MgCl 2 ·6H 2 O0.129g / L,...

Abstract

The invention discloses a method for raising hydrogen production efficiency of microalgae and belongs to the field of a biological energy source. The method comprises the following steps: hydrogen-production microalgae cells are cultured in a medium until the exponential growth phase; the microalgae cells are collected, and the microalgae cells are transferred to a microalgae hydrogen-production medium containing organic matters, deoxygenization and sealing are carried out, and the microalgae cells are continuously cultured in a dark environment for a certain time, wherein the organic matters contain at least one of glucose, fructose, acetate, pyruvic acid, 3-phosphoglycerate, malic acid and amino acid and at least one of sodium salts and sylvite of the above organic matters; and finally, the microalgae cells are again placed in a light environment to induce water decomposition to produce hydrogen. It is verified through experiments that hydrogen production efficiency of microalgae can be remarkably raised by adding the organic matters to the microalgae hydrogen-production medium. The method has characteristics of novel technology and remarkable effect and the like, is simple and reliable, and has important practical application value in the field of new energy.

Description

technical field [0001] The invention belongs to the technical field of bioenergy, and in particular relates to a method for improving the hydrogen production efficiency of microalgae. Background technique [0002] In recent years, with the massive consumption of fossil energy such as coal, oil, and natural gas, the depletion of traditional energy is accelerating. At the same time, environmental problems such as acid rain, photochemical smog, haze, and greenhouse effect caused by the massive consumption of fossil energy are also becoming more and more serious. Sustainable new energy has important strategic significance. [0003] Hydrogen energy is regarded as an ideal future energy source due to its advantages of cleanliness and high efficiency. The traditional production methods of hydrogen mainly include thermal decomposition and electrolysis. These two methods rely heavily on fossil energy, so the sustainability of their development has been questioned. In addition to ph...
