The Characteristics and Kinetic Equation of 4-CP Biodegradation by Fusarium sp. HJ01

Abstract

The stain of Fusarium sp. HJ01 used in 4-chlorophenol (4-CP) degradation was isolated in our laboratory. The effects of pH, temperature, 4-CP concentration, carbon source on 4-CP degradation rate were studied. It was concluded that Fusarium sp. HJ01 could grow with 4-CP as the sole carbon and energy source. 4-CP concentration of 100mg/L in the pH range of 4~10 and temperature range of 25°C~35°C could be degraded completely. The capacity of 4-CP degradation was effectively enhanced by the addiction of sucrose. The kinetics of 4-CP degradation could well accord with the Haldane model for 4-CP as the sole carbon source and with first order equation for added other sucrose.

The Characteristics of p-Chlorophenol with Cu²⁺ Biodegradation by <i>Fusarium</i> Sp. 

“…It was isolated from contaminated bentonite and identified as Fusarium sp. HJ01 proliferatum through molecular biological identification [8][9]. The acclimation operations were done that the strain was inoculated in the liquid culture medium.…”

“…Analysis technique. The concentration of 4-CP was measured by the UV spectrophotometer at 242 nm wavelength at room temperature [8]. The relationship between concentration of 4-CP and time was gained by the zero, or first and second order reaction equation.…”

“…Some studies were reported about 4-CP degradation by Fusarium sp. [5][6][7][8]. However, few studies were reported about 4-CP biodegradation with Cu 2+ coexistence by Fusarium sp.…”

The Characteristics and Kinetics of 4-CP with Pb²⁺ Biodegradation by <i>Fusarium</i> sp.

“…Works were reported about 4-CP degradation by Fusarium sp. HJ01 [4][5][6][7]. However, bacteria need a good environment for growth and be sensitive to heavy mental, while the fungi have a tolerance to heavy metal and can defense the metal toxicity efficiently.…”
