Example Embodiment

[0028] The following is a detailed description of the method for simple expansion and cultivation of photosynthetic bacteria used in landscape water treatment of the present invention in combination with specific examples. According to the following description and claims, the advantages and features of the present invention will be clearer.

[0029] A simple method for expanding and cultivating photosynthetic bacteria for landscape water treatment, including the following steps:

[0030] Step 1: Provide a strain of photosynthetic bacteria.

[0031] Preferably, commercial photosynthetic bacteria preparations can be purchased directly from the market as photosynthetic bacteria species.

[0032] Step 2: Prepare bacterial culture medium. According to the growth characteristics of photosynthetic bacteria, a suitable bacterial culture medium formula is selected. Specifically, in order to minimize the economic cost of photosynthetic bacteria liquid culture used for landscape water treatmen...

Abstract

The invention discloses a simple spread cultivation method for photosynthetic bacteria for treating landscape water, belonging to the technical field of biology and being used for solving the problem of overhigh use cost of the traditional photosynthetic bacteria for treating landscape water. The method comprises the following steps of firstly, providing a photosynthetic bacterium strain; secondly, preparing a bacterium culture medium; next, inoculating photosynthetic bacterium strains to the bacterium culture medium according to a reserved number to obtain a photosynthetic bacterium inoculation solution; finally, placing the photosynthetic bacterium inoculation solution under the sun to culture for reserved days to obtain a photosynthetic bacterium fermentation solution, wherein 20-25% of photosynthetic bacterium fermentation solution can be retained for the photosynthetic bacterium strain, the rest of the photosynthetic bacterium fermentation solution can be directly used for treating landscape water on site, and the original photosynthetic bacterium strain can be repeatedly cultured 2-3 times. By using the method, not only is the transportation cost of a photosynthetic bacterium solution reduced, but also the quality stability of the photosynthetic bacterium solution for treating the landscape water is ensured.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a simple method for expanding and cultivating photosynthetic bacteria for landscape water treatment. Background technique [0002] Photosynthetic bacteria are a group of microorganisms that use light as energy and can use organic matter, sulfide, ammonia, etc. in nature as hydrogen donors and carbon sources for photosynthesis under anaerobic light or aerobic dark conditions. The role of photosynthetic bacteria in sewage fermentation treatment has become increasingly prominent. For example, photosynthetic bacteria (Rhodopseudomonas capsulata) can convert carcinogen nitrosamines into non-toxic compounds. For organic wastewater with biochemical oxygen demand (BOD) as high as several thousand mg / L, some biofilm methods and active Aerobic treatment methods such as sludge method are difficult to tolerate, but photosynthetic bacteria can withstand it, so photosynthetic bacteria...
