Effects of nutritional conditions on growth of Beauveria bassiana

Abstract: The effects of different carbon sources, nitrogen sources and trace elements on the growth and spore production of three kinds of Beauveria bassiana on meadow moth were studied. The results showed that organic carbon sources were suitable for three kinds of B. bassiana. The best organic carbon source was glucose and followed by sucrose. For inorganic carbon source, a few of which were taken only by BbS05. The best nitrogen source was yeast powder. The highest growth and spore production of three B. bassiana were obtained when C∶N=40∶8. For BbD01, the mixture of Fe、Mn addition showed the best facilitation. For BbS05, the most efficient mixture was the group of Fe、Zn、Mn and followed by the group of Fe、Zn. However, none of single trace elements or their mixture was useful to BbY03.
