Fig. 2From: Degradation of low density polyethylene by Bacillus speciesWeight loss of LDPE film samples. Symbols are: filled circle, LDPE samples incubated with B. subtilis; open circle, LDPE samples incubated with B. licheniformis; and filled triangle, negative control, indicating LDPE specimens incubated in the flask in which bacterial cells were not inoculated. All experiments were performed independently in triplicate. See the Methods section for the details on calculating the weight loss of LDPE film samplesBack to article page
