A Novel Cyclone Separator for Conidial Powder of Several Fungal Biocontrol Agents
摘要
Abstract
There is a great potential of fungal biocontrol agents against pest insects and plant disease. Aerial conidia, the primary inoculums for effective infection of fungal biocontrol agents, can be readily produced in vitro by solid-state fermentation (SSF). Quality and quantity of conidial powder are key factors for formulation, and can dramatically affect field application as well. In this study, collection efficiency of three separators were evaluated on aerial conidial powder of three representative isolates, Beauveria bassiana, Metarhizium anisopliae and Trichoderma viride, synchronously produced in upright multi-tray conidiation chamber by SSF. For the three isolates, self-developed cyclone separator had a maximal yield of 2.5×1012 per kg rice, which was higher than MH5 cyclone separator and 200 mesh stainless screen. All technical parameters on collection efficiency and yield were all acceptable. The results suggest that the self-developed separator can be potentially developed into commercial device for collection of aerial conidia.关键词
