Elertrofusion of Building Coupling System for Degrading Anthracene and Fusants'' Choices
选育蒽降解微生物耦合系统菌株的电融合及融合子的筛选

Some researches have been carried out for the electro fusion of building coupling system for degrading anthracene and the choices of fusants. During the experiments, total rate of fusion stable in alternation current frequency 500 kHz, impulse intensity 300 V/cm, impulse width 5 micros, amount of impulse 2 and alternation current intensity 20-40 V/cm were found. The resistant plate with erythromycin and ampicillin can screen the fusant of autochthonous bacterium and surfactant-producing bacterium. The resistant plate with anthracene and karnamicin can screen the fusant of autochthonous bacterium and efficient anthracene-degradation bacterium. The new fusants were found to have stable fluorescent characteristics.
