(1) Rhizospheric nitrifying bacteria tended to increase under drought stress.

(2) Studies show that membrane bioreactor has good nitrifying ability.

(3) So the study of the relationship between nitrifying activities of mono-substituted arene and nitrification intensity of mixed acid is of doctrinal importance and practical application value.

(4) Nitrifying activity was obviously enhanced 70%, which of BEIBEI sample reached 100%; We used ss medium to detect the change of number of intestine bacteria .

(5) The influence of nitrification efficiency with adding nitrifying bacteria to the activated sludge process was investigation.

(6) The soil naturally swarms with nitrifying bacteria, but their growth may be checked by various causes.

(7) Nitrifying bacteria have the properties of obligate autotrophy and slow growth. And it's the rate limiting component in circulation of Nitrogen.

(8) In the liquid-phase hydrogenation of nitrifying mixture, four elements Raney Nishows excellent catalytic activity and strength, compared with many kinds of catalyst.

(9) The result showed that the measurement of nitrifying rate and nitrobacteria count was an important basis for determining the denitrification effects.

(10) As a beneficial bacteria[sentencedict.com], nitrifying bacteria have become the hot research on water quality improvement.

(11) Nitrifying organisms are sensitive to a wide range of organic and inorganic compounds and at concentrations well below those concentrations that affect aerobic heterotrophic organisms.

(12) The number of heterotrophic bacteria and nitrifying bacteria increased with the time of the hydraulic retention time, contrary to the nitrobacter.

(13) The nitrogen loss in internal-loop granular sludge bed nitrifying reactor was studied, and the results indicated that ammonia escape is an important factor causing nitrogen loss.

(14) The numbers of nitrosation bacteria and the nitrifying bacteria were counted with the MPN, Contrast experiment on the color reactions to judge nitrite and nitrate in the culture medium was performed.

(15) Living bacteria - the product use the micro-capsule technology to protect the live bacteria in a dormant state. The product is not nitrifying bacteria medium.

(16) There are significant correlation between nitrogen removal efficiency and the biomass of nitrifying bacteria in water and the plants. Sentencedict.com

(17) In both the urea and ammonium sulfate N-sources, the effects of PBP to soil nitrifying potential and nitrifying capacity was studied by incubation experiment.

(18) The dissolved oxygen had greater effects on heterotrophic bacteria, ammonifying bacteria and nitrifying bacteria.

(19) The purpose of this study is to improve the concentration of nitrifying bacteria in the active sludge through improving substrate concentration.

(20) Short rod bacteria and spirillum were dominant in the denitrifying reactor. While cocci were the dominant bacteria in the nitrifying reactor.

(21) The amounts of trace S and P in puffed food were determined by ICP-AES with high pressure nitrifying pot to transfer into sulfate and phosphate.

(22) Corrosive microorganism may lead to metal corrosion. We mainly study iron bacteria, sulfur oxidizing bacteria, sulfate-reducing bacteria, nitrifying bacteria and denitrifying bacteria.

(23) The start - up of the ANAMMOX bioreactor by autotrophic nitrifying biofilm was studied.

(24) At present the microecoligical agents used in purifying culture water body mainly include photosynthesis bacteria, nitrifying bacteria, bacillus , bdellovibrio and compound microecoligical agents.

(25) The industrial application of low molecular nitroalkane is widespread day by day. it is a reason-able way to use propane as the raw material to produce low molecular nitroalkane by nitrifying.

(26) The experimental results reveal that this method is suitable to determine the activity (14%) of higher microorganisms from the SBR nitrifying system.
