Embodiment 1

[0030] 1. Preparation of spore suspension

[0031] On the aseptic operating table, gently scrape the spores of Penicillium DH-1 growing on the solid medium on the slope with an inoculation loop to make the spores fall off. Rinse the solid slope repeatedly with 10 mL of sterile saline until the spores are suspended in the saline. Use a pipette to transfer the rinsed physiological saline containing Penicillium DH-1 spores to a 100 ml Erlenmeyer flask, and add sterile deionized water so that each ml of deionized water contains about 108 spores. Then place it in an air bath shaker and shake for 1 hour, so that the spores are uniformly dispersed, and the spore suspension is obtained.

Abstract

The invention relates to a method for a mycelium pellet to form a mixed mycelium pellet by adsorbing photosynthetic bacteria and in particular relates to the method for the mixed mycelium pellet in environmental bioengineering. The method comprises the following steps of: preparing a spore suspension, preparing the mycelium pellet, preparing a photosynthetic bacteria cell suspension and preparing the mixed mycelium pellet by an adsorption method. The preparation of the mycelium pellet is carried out after obtaining the spore suspension and comprises preparing a mycelium pellet fluid nutrient medium and culturing the mycelium pellet. The preparation of the photosynthetic bacteria cell suspension is carried out after forming the mycelium pellet and comprises carrying out enrichment culture of the photosynthetic bacteria, preparing a bacteria fluid nutrient medium, scattering and uniformly mixing the photosynthetic bacteria to carry out dark aerobic culturing, and discarding supernate from a culture solution in the culturing to prepare the photosynthetic bacteria cell suspension. Spare mycelium pellet is rinsed thoroughly, pH is adjusted by NaOH and HCl, and the spare mycelium pellet is subjected to dark aerobic culturing to form the mixed mycelium pellet. By utilizing the method, the treatment effect on organic wastewater is improved. The method has important significance for treatment of the organic wastewater by utilizing the photosynthetic bacteria in a large scale.

Description

technical field [0001] The invention relates to a method for environmental bioengineering mixed mycelium balls, in particular to a method for mycelium balls to absorb photosynthetic bacteria to form mixed mycelium balls. Background technique [0002] Photosynthetic bacteria (Photosynthetic bacteria, PSB for short) is a kind of primitive photosynthetic system microorganism with broad application prospects in the field of sewage purification. This type of microorganism has the characteristics of flexibly changing the type of metabolism with changes in environmental conditions, and can degrade organic matter in wastewater under anaerobic light and aerobic dark conditions. In addition, PSB also has excellent characteristics such as simple process equipment, high organic load, recyclable bacteria, and no secondary pollution. Based on this, in recent years, scholars at home and abroad have carried out extensive application and in-depth research on photosynthetic bacteria, and hav...
