The 39 strains of cellulose-decomposing microorganisms were isolated from rubbish compost by Dubos liquid medium with Xinhua filter paper as the sole carbon source.We got 10 colonies surrounded by some distinct zones of clearing in cellulose-congo red agar medium from the 39 strains above.By measuring the enzyme activity of liquid culture filtrates,we got a strain(termed B-6)with higher cellulase activity.In order to evaluate our screening,the results of liquid and solid fermentation were compared between s...
