24. Dynamics of root microorganisms in closed hydroponic cropping systems
Abstract : Greenhouse production of vegetables in closed hydroponic cropping systems is a resource-efficient technique for the production of high-quality produce with a high yield per unit area. While this type of cropping system allows savings in terms of water and nutrient use, the recirculation of water increases the risk of pathogen dispersal. READ MORE

25. PCR-based detection of microorganisms in complex biological samples
Abstract : The detection of microorganisms by PCR can be divided into four steps: (1) sample collection, (2) sample preparation, (3) DNA amplification and (4) detection of PCR products. The major problem in developing PCR-based detection methods is the sample preparation step. READ MORE
