Abstract

This study was carried out to improve the liquid culture methods of Paecilomyces japonica. The results show that the size of granular mycelium is smaller when the shaking speed is increased. Especially, the granular mycelium is the smallest at the shaking speed of 150rpm under the photoperiod of 12L-12D. Dry weight of mycelium was averagely 1.216 g in the Sikworm larva (SL) medium, and the weight was 2 times heavier than in the Potato dextrose (PD) medium. By adding 6 g of 6 mmbeads in the SL medium, the dry weight is increased to 1.332 g. The optimal addition of silkworm larval powder to the culture medium for gest harvest was 1.360$\pm$0.67 g in dry weight.
