Students were assigned to isolation of bacteria, actinomycetes and molds from campus’s soil and Shennongjia’s soil, which they had collected during summer filed practice. The experiment is aimed at helping students to learn the method for determination of microorganism numbers in soil and master the basic techniques about plate count. The subsequent experiments involve techniques, such as aseptic technique, microscopical technique, pure culture technique, separation and purificati
