For 480 days of decomposition, the decomposition rate was highest in soil with medium fertility and lowest in soil with low fertility among three type of fertility. The decomposition of water soluble factions and lignin were promoted in medium fertility soil. However, alcohol-benzene soluble fraction, and semi-cellulose and cellulose fraction were decayed acceleratedly in soil with high fertility. Furthermore, more humic substance was formed and energy states of decayed corn stalk was highest in soil with high fertility.

More information about their structure and function relationship will be meaningful in understanding the molecular mechanism of ion pump and conformation alteration during ion transport and sensory transduction. In this paper, we report screening strains from samples collected from Ebi lake and Altun moutain Aqik lake, Xinjiang Province, and got 60 clonies from them. We choose 8 of them for further investigation and confirmed that they all belong to the Halobacteriaceae genus and through comparasion of several minute diffrerence medium we had the optimal medium for their growth.. Through this procedure we had established a set of methods for screening clonies from wild environment.and isolation and purification of these archaerhodopsin. Furthermore we used PCR method to identify their DNA sequence.
