Pararosaniline was the most accurate and sensitive method of determining SO2 residue, and it was fit for the samples of any SO2 content. Improvement pararosaniline method was only fit for the samples of high SO2 residue. Iodometry was not fit for the deep color samples and low SO2 residue samples. The fast determination method could be used the quality and semi-quantitative determination of SO2 residue in edible fungus.

When the TN:TP ratio was 25:1,V.spiralis had the best growth, with a biomass increment being 54% and 31% higher than that when the TN: TP ratio was 12.5:1 and 50:1, respectively, while the growth of periphyton, especially of epiphytic algae, was the worst, giving the least adverse effects on V. spiralis, indicating that a 25:1 of TN:TP ratio in eutrophic water was optimal for the growth of V. spiralis. However, such an optimal TN: TP ratio only worked when the nutrients concentration in eutrophic water was below the limited level, otherwise, it could be failed to be applicable.
