Problems solved by technology

But there are still the following deficiencies: 1. In addition to consuming a large amount of power and increasing costs, excessive ventilation and increased stirring speed will affect the morphology of some biological bacteria to a certain extent.
In addition, with the rapid growth of the number of phosphorus bacteria, the viscosity of the material gradually increases, the solubility of oxygen also gradually decreases, and the oxygen supply contradiction intensifies, resulting in the occurrence of anoxic state and affecting the synthesis of products.
This phased contradiction between supply and demand of dissolved oxygen is difficult to completely solve only by changing the ventilation rate and stirring speed, thus affecting the yield of phosphorus bacteria in biofertilizers

Embodiment 1

[0012] Embodiment 1: Before inoculating the phosphorus bacteria, add 0.1-1.0 grams of oxygen-enhancing agent amide peroxide. The number of phosphorus bacteria in the product is 1.8-2.4×10 9 per milliliter, the yield of phosphorus bacteria number increased by 125-160%.

Embodiment 2

[0013] Embodiment two: After fermenting and cultivating for 1-8 hours, 0.1-1.0 grams of oxygen-enhancing agent amide peroxide is added, and the bacterial count of the product is 2.5-4.1×10 9 per milliliter, the yield of phosphorus bacteria number increased by 210-360%.

Abstract

The present invention relates to a method for raising yield of phosphoric bacteria of biological fertilizer, it is characterized by that in the liquid culture medium for fermentation of phosphoric bacteria it not only contains carbon source, nitrogen source and inorganic salt, but also it increase oxygenation agent. Said method can promptly supplement lots of oxygen gas required for thalline being in logarithmic growth phase, and can raise utilization rate of nutrient source so as to raise yield of phosphoric bacteria by 1-5 times, reduce cost and raise fertilizer efficiency.

Description

technical field [0001] The invention relates to a method for increasing the yield of phosphorus bacteria in biological fertilizers. Background technique [0002] In the fermentation process of phosphorus bacteria in bio-fertilizers, the commonly used liquid culture must include sufficient amounts of carbon sources, nitrogen sources, inorganic salts and oxygen. That is, it contains a sufficient amount of carbon, nitrogen, an appropriate amount of phosphorus, some inorganic salts containing sulfur, magnesium, calcium, potassium, and sodium, and trace elements such as iron, copper, zinc, and manganese. During the fermentation process, the main factors affecting the growth and reproduction of microbial populations are: the choice of medium, the concentration of oxygen, the pH value of the medium, the culture temperature, the concentration of soluble substances in the medium, etc. When the medium, pH value, temperature and other technical parameters are optimally determined, the...
