Identification and phylogenesis of ammonifying bacteria from pond water of Litopenaeus vannamei;

The most probable number (MPN) method was employed to determine the distribution and role of four nitrogen cycle bacteria, including ammonifying bacteria, denitrifying bacteria, nitrosobacteria and nitrobacteria, in East Lake, Wuhan.

Test results show that the amounts of ammonifying bacteria,nitrification and denitrification bacteria are 5.

Numbers of ammonifiers and ammonification rate in self-purification pools of Paralichthys olivaceus;

In the present study,viable numbers and metabolic activities of aerobic heterotrophic bacteria, ammonifiers,ammonia oxidizing bacteria(AOB),nitrite oxidizing bacteria(NOB)in marine biofilms were investigated.

Numbers and metabolic activities of heterotrophic bacteria, ammonifiers and ammonia oxidizing bacteria in the Nereis close-recirculating culture system;

Primary study on screening of bacteriocin-like substance producing bacterium LC47 and its fermentation substance;

Screening of bacteriocin-like substance producing lactic acid bacterium and its characteristics;

Attempts were made to produce bacteriocin-like substance by immobilized cells of Bacillus subtilis LL18-4 entrapped in calcium alginate beads.

In this paper,the bacterial kinds and quantity of sea water and intertidal organism influenced by discharge of polluted waste water in Zhoushan Port were studied.
