Many are found in tropical and subtropical areas of the world, where the accumulation of high concentrations of metals may afford some protection against plant-eating insects and microbial pathogens.

The field applications of microbial wax prevention technology in Daluhu Oilfield and Xiaoying Oilfield show that the well wax deposition and oil bed protection problems were solved effectively.

Because the product of environmental protection raw and auxiliary materials, non-toxic harmless to humans, and to avoid microbial breeding, so conducive to health.
