There are substrata competition between the heterotrophic denitrification bacteria and ANAMMOX bacteria when organics the influent.

This paper studied the abilities of denitrification and kinetics of denitrification of heterotrophic denitrifying bacteria.

研究电极生物膜反应器中异养反硝化菌的脱氮能力及脱氮动力学.

Selfing heterozygotes halves the heterozygosity , and thus outbreeding maintains heterozygosity and produces a more adaptable population.

自交杂合子有一半杂合性, 因此远系繁殖可以产生适应能量更强的种群.

The average heterozygosity of offspring and polymorphic information content ( PIC ) etc were lower than those of their parents.

子代的平均期望杂合度(He) 、平均观测杂合度 ( Ho)和平均多态性信息含量(PIC ) 等指标均低于亲代.

Thus an intermediate phenotype will be produced in the heterozygote.

这样在杂合体中就存在中间过渡类型.

The research deals with functional nano powder, fabrication heterozygous material, 1-D nano material and devices.

Methods: Nine heterozygous mutation carriers and nine healthy controls were investigated.

方法: 调查9名杂合子突变携带者和9名健康对照者.
