Can sodium humate be used with lactic acid bacteria?

The use of sodium humate and fertilizer products can help, and it can also be used in combination with the use of shading products to help kill moss. However, although sodium humate is safe and efficient, there are some things to be aware of during use.

Do not mix with drugs that are prohibited for alkaline substances

This is mainly because the sodium humate is an alkaline substance, the pH of the pure sodium humate is 8.0-9.5, and the pH of the second and third grades is 9.5-11.0, which needs attention.

Do not mix with organic acids

Since sodium humate is alkaline, it is best not to mix it with acidic substances in the actual application process, especially organic acid products.

Whether it can be used with lactic acid bacteria remains to be explored

A variety of lactic acid bacteria have been used in aquatic products, and studies have shown that sodium humate has a certain inhibitory effect on Lactobacillus plantarum under liquid conditions. Studies have shown that 1%-5% sodium humate reduces the viable count of Lactobacillus plantarum, but can reach the highest growth point 6h in advance; after 3% sodium humate, the organic acid yield of Lactobacillus plantarum changes, and The colonies become smaller and the cells become thicker.

Transmission electron microscopy results showed that sodium humate caused the cell wall and cell membrane structure of Lactobacillus plantarum to become blurred. Therefore, sodium humate under liquid conditions can inhibit the growth of Lactobacillus planta by changing the metabolic pathway and morphological structure. However, according to the research of many people, adding 2% sodium humate in the fermentation substrate and the seed liquid respectively has an effect on the viable cell number, the organic acid content, the reducing sugar content and the synthetic extracellular polysaccharide in the solid fermentation product of Lactobacillus plantarum.

Studies have shown that the addition of 2% sodium humate in the substrate and seed solution stimulated the growth of Lactobacillus plantarum in the early stage of solid fermentation of Lactobacillus plantarum (24h), and the specific mechanism was further studied. Therefore, whether humate can be used together with lactic acid bacteria in aquaculture needs further exploration.
