Abstract

The invention belongs to the technical field of breeding, and discloses a culture technique of pasty photosynthetic bacteria. The technique is as below: multiple times of subcultivation and multiple times of culture, final pH adjustment with acetic acid and continued culture, so as to obtain the pasty photosynthetic bacteria product. The product has the characteristics of stable quality, long preservation time and high bacteria number; after using, the product can sink to the bottom to play the role of rapid improvement in pond sediment, so as to overcome the problem that routine photosynthetic bacterial liquid is difficult to act on the bottom of the pond.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and in particular relates to a paste-like photosynthetic bacteria cultivation method. Background technique [0002] Photosynthetic bacteria ( PSB ) are relatively ancient prokaryotic organisms that widely exist in nature and have a primitive photosynthetic system, which can perform photosynthesis without oxygen release under anaerobic conditions. Photosynthetic bacteria have a variety of physiological functions, and their metabolic types are extremely diverse. There are various vegetative growth modes such as photoautotrophy, heterotrophy and polytrophy. They have photosynthesis, carbon fixation, degradation of macromolecular organic matter, nitrogen fixation, denitrification, nitrification, and denitrification , sulfide oxidation and other metabolic methods have shown their strong advantages in the purification of aquaculture water quality. [0003] Photosynthetic bacteria, as purifiers, ha...
