  • The researches with pesticides in soil were divided several categories such as run off from soil surface, adsorption and desorption in soil, leaching through soil, degradation and decomposition studies, fates in soil, monitoring survey and development of analytical procedures and so on. In this paper it was reviewed that the research results published in Korean journals since 1996, in connection with the former review as 'Evaluation on the effects of pesticide residues to agroecosystem in Korea'.

  • The recovery and purification of a paclitaxel from plant cell cultures is essential to commercial process. This review describes a large-scale recovery and purification method for producing paclitaxel, to guarantee high purity and yield from plant cell cultures. Also, the process of separation and purification is optimized in conjunction with a extraction step, pre-purification, purification, and polishing (drying) as an integrated process to meet final product quality requirements such as purity, residual solvents, product morphologies, impurities, bacterial endotoxin, etc. This information is very useful for production and quality control of pharmaceuticals in commercialization step.
