Abstract
Spirulina biomass residues (SBR) are left behind after pigments extraction. Residual essential nutrients include protein, carbohydrate and lipid. This research focused investigated SBR from phycocyanin extraction as a protein source for Cordyceps militaris culture to replace the use of commercial Eri silk worms and produce better amounts of some valuable nutrients, as well as improve consumer safety. C. militaris samples were cultured on fruiting body induction medium (FIM) using dried Spirulina and dried SBR at 0, 1, 2.5, 5, 10% w/v compared with the FIM with silkworm larvae in the dark at 25 ± 2 °C for 2 weeks, then cultured under illumination (50 μmol/m−2/s−1) for 16 h at 20 ± 2 °C for 10 weeks. The results showed that C. militaris cultured in the FIM supplement with 1% dried SBR produced the highest amount of cordycepin (32.87 mg/g-DW), which was higher than in other studies and in silk worm product.
