查询词典 acidic

Enterobacter aerogenes was irradiated by He-Ne laser to optimize the laser mutagenesis condition, and to test the heredity, aciduric and hydrogen-producing potential of the mutant. An aciduric mutant with steady hydrogen-producing capability, which was able to grow at acidic pH of 3.0, was obtained. Its capability of hydrogen production was measured in the batch culture experiment.

Under the different pH conditions, the migration and transformation behavior of each form of phosphorus released from the lake sediments into water body was studied by means of simulation. The results show that under alkalic condition or acidic condition, the temporal and spatial distribution of phosphorus in the water body changes with its releasing mechanism, and its migration and transformation behaviors are various. The change of pH value has no obvious effect on such transformation, but the total phosphorus in the water body has substantial effect on the concentration change of various forms of phosphorus.
