You are a scientist studying a marsh area contaminated with PCBs, toxic chemical compounds found commonly in industrial waste. Initial microscopic analysis of the soil reveals the presence of motile cells that measure in the micrometer range. You hypothesize that these microbes may be useful in bioremediation of the toxic waste. Thinking about microbial sampling and isolation, describe a method for culturing these microbes back in your laboratory.
