Bacterial Agent

Halotolerant Bacteria

Description Form:

Powder Main ingredients: Bacillus & coccus which can grow spore(endospore) Living bacterium content: ≥20 billion/gram

The test shows that the following physical and chemical parameters for bacterial growth is most effective: 1.pH: In the range of 5.5 and 9.5, most rapidly growth is between 6.6-7.4 , the best efficiency is at 7.2. 2.Temperature: It will take effect between 10℃-60℃.Bacteria will die if the temperature is higher than 60℃. If it is lower than 10℃, it will not die ,but the growth of bacteria will be restricted a lot. The most suitable temperature is between 26-31℃. 3.Micro-Element: Proprietary bacterium group will need a lot of elements in its growth , such as potassium, iron, sulfur, magnesium, etc. Normally , it contains enough elements in soil and water. 4.Salinity: It is applicable in salt water and fresh water ,the maximum tolerance of salinity is 6%. 5.Poison Resistance: It can more effectively resist chemical toxic substances, including chloride, cyanide and heavy metals ,etc. *When the contaminated area contains biocide,need to test the effect to bacteria.
