Summary: | This study demonstrated the potential for managing starch processing waste (SPW) by bioconversion to
Cordyceps militaris
mycelia using solid state cultivation (SSC) and submerged liquid cultivation (SLC). The growth characteristics of
C. militaris
mycelium were accessed and compared for SSC and SLC systems on SPW under various conditions of initial SPW concentration, pH, and operating temperature. To quantify the mycelial biomass in SLC, original primer sets targeting the 18S rRNA gene of
C. militaris
were developed. In SSC, a maximum mycelial growth rate (543.1 mm
2
/day) was predicted to occur at 25.6 g SPW/L, pH 5.5, and 23.8 °C. In SLC, a maximum mycelial growth rate (1918.6 mg/L/day) was predicted to occur at 35.5 g SPW/L, pH 5.5, and 22.0 °C. Temperature was suggested as the most significant factor in both systems. The higher optimum substrate concentration observed for SLC than for SSC was likely due to difference in mycelial morphology and mixing effect. |
