| Summary: | Carbazole is a significant environmental pollutant and not a biodegradable compound that has impact
environment and human health. This project was conducted to examine the ability of marine CAR -degrading
bacteria from marine environment in the carbazole degradation rate analysis. The isolated strains M02 of
Thalassospira projimdimaris was obtained from previous undergraduate student. M02 was enriched with
ONR7a liquid media before proceed to other processes. The isolated strain was cultured with [0.1 %] of
carbazole in 14 days and the sample was taken on every two days from day two to the day 14. Degradation of
the compound. was quantified by using Gas Chromatography-Mass Spectroscopy (GC-MS) method after the
extraction with combination of Dichloromethane and Ethyl acetate chemical substances. CFU numbers
increase as the concentration of the substrate increase from 0.1 % to 0.7%. Biphenyl shown positive of
growth in different substrate test compared to fluorene, dibenzofuran and dibcnzothiophene. |
