Research on the application of microbial biofilm in soil and water conservation
Soil and water conservation is the fundamental guarantee for food production,and soil erosion is a serious issue in China due to human activities and environmental changes.With the development of technology and biology,the influence of microbial activities in the soil upon soil properties has attracted increasing attention.Microbes in the soil exist in b free cell and biofilms.In this study,the value of extracellular polysaccharides and γ-polyglutamic acid in the biofilms of soil was explained in terms of maintaining soil moisture and fertility,improving soil structure and enhancing soil stability.It also analyzed the future potential of microbial biofilms in soil and water conservation as well as ecological agriculture.
