The invention relates to a culturing medium and fermentation method for producing erythrocin through fermentation of streptomyces erythreus. A primary seed medium, a secondary seed medium and a fermentation medium for producing erythrocin through fermentation of streptomyces erythreus all contains sucrose and a corn steep liquor. According to the invention, the corn steep liquor, urea, sucrose, and other intermediate-acting carbon sources and nitrogen sources are adopted to substitute original slow-acting carbon sources and nitrogen sources; moreover, the corn steep liquor, urea, and sucrose are soluble in water, so that the viscosity of the fermentation liquor is lowered, the dissolved oxygen is increased, the utilization speed is increased, especially during the later period of fermentation, the solid residue at the end of the fermentation is reduced, the bacteria dregs and the BOD content and the COD contend in the waste water are all greatly reduced, energy-reserving and consumption-lowering are both realized, and the good effects of treatment from the source and clean production are achieved.

The invention provides an aquatic-product compound amino acid bacterial fertilizer containing triacontanol and a preparation method thereof, and in particular provides an aquatic-product compound amino acid bacterial fertilizer containing triacontanol which can quickly cultivate algae at a low temperature, and can quickly form excellent water color within 2-3 days after sudden death of algae. Materials for preparing the compound amino acid bacterial fertilizer comprise triacontanol raw powder, alcohol, compound amino acid primary liquid, peregal, lauryl sodium sulfate, sodium silicate, zinc sulphate heptahydrate, ferrous sulfate, sodium molybdate, cobalt chloride, boric acid, manganese chloride and spore bacteria liquor. Free amino acid and each trace element in the aquatic-product compound amino acid bacterial fertilizer can be directly utilized by algae after being applied to a pond, so that conversion is quick and the algae photosynthesis is promoted; the low-concentration triacontanol can promote quick growth of beneficial algae such as diatom, green algae, and the like, at a low temperature, strengthen activity of the algae, so that fertilizer can quickly cultivate algae at a low temperature, and excellent water color can be quickly formed within 2-3 days after sudden death of algae.

The invention relates to a system and a method for ecologically restoring a riverway / lake and reservoir water body. The system comprises micro-nano aeration contact oxidation equipment, a composite ecological floating island and a riverway / lake and reservoir shore zone, through the micro-nano aeration contact oxidation technology, the biological membrane soft carrier has the characteristics of large specific surface area, easy biological attachment and the like, and effectively intercepts indigenous microorganisms and efficient degradation microorganisms slowly released by the composite ecological floating island biological filler matrix. Degradation of organic pollutants and removal of nitrogen and phosphorus are promoted through combined action of micro-nano aeration of a river channel and microorganisms in a biological filler matrix; emergent aquatic plants on the composite ecological floating island and submerged plants, floating-leaved plants and benthic animals in a river channelare combined to obviously improve the water body environment, improve the water body transparency and improve the water body self-purification capacity, and the water body reaches or is superior to surface V-type water.

The invention relates to a fermentation method for erythromycin. According to the method, a mixture containing glucose is used as a feed supplement carbon source, and adjustment of fermentation yeast basis and supplement technological adjustment of the carbon source are further matched. According to the novel erythromycin fermentation technology, the erythromycin fermentation yeast basis formula used in the glucose supplement technology and the control condition of the carbon source are given in the fermentation process. The fermentation metabolism process is changed by adjusting the fermentation yeast basis formula and the carbon source supplement type, and therefore the purposes of saving raw material cost of the carbon source, improving the fermentation level, weakening extraction difficulty, saving energy and reducing consumption are achieved.
