The aim of the project is to investigate the microbial communities involved in the degradation of polymers like cellulose or proteins in paddy soils. Therefore different paddy soils across south Asia should be studied and microbial communities involved in cellulose degradation and protein mineralization should be compared to upland soils from the same regions to describe biogeographical pattern of these functional communities typical for paddy soils. In addition the development of typical microbial communities involved in cellulose and protein degradation in paddy soils should be studied in a greenhouse experiment using a) upland soils and b) tidal wetland soils with no history in paddy cultivation as starting material. These two types of soil should be used for paddy cultivation and the development of typical functional community profiles as well as typical turnover rates should be studied using stable isotope labelled litter material. This project will help to link carbon and nitrogen profiles typical for paddy soils with their architects, microbes involved in the corresponding turnover processes.

该项目的目的是调查参与降解稻田土壤中的纤维素或蛋白质等聚合物的微生物群落。因此，应研究南亚不同的水稻土，并将参与纤维素降解和蛋白质矿化的微生物群落与相同地区的旱地土壤进行比较，以描述这些水稻土典型功能群落的生物地理格局。此外，应以a)旱地土壤和b)无水稻耕作历史的潮汐湿地土壤为起始材料，在温室实验中研究参与水稻土壤中纤维素和蛋白质降解的典型微生物群落的发展。这两种类型的土壤应用于水稻种植，并应利用稳定同位素标记的凋落物研究典型功能群落剖面的发展和典型周转率。该项目将有助于将水稻土典型的碳和氮剖面与其建筑师、参与相应周转过程的微生物联系起来。
