An Organic Solvent Widely Used in Industrial Processes-1,1,1- Trichloroethane TCA)-Is

Multiple Choice

An organic solvent widely used in industrial processes-1,1,1- trichloroethane TCA) -is a major environmental pollutant affecting human health and damaging the ozone layer. Recently, researchers isolated the first bacteria able to degrade TCA. They found that the bacteria use hydrogen as an electron donor, TCA as electron acceptor, and acetate as a carbon source. Based on the preceding information, deduce the method used to isolate these bacteria.

A) enrichment culture
B) seeding
C) direct sequencing
D) Gram staining
