Abstract

Dunaliella salina is a group of green algae that produces pigment (chlorophyll and carotenoids) and used as live feed in hatchery especially for marine commodities. Nitrogen and phosphorus are needed by D. salina can be obtained from P. radiatus fertilizer. The purpose of this research is to know the effect and optimal dose of P. radiatus fertilizer to density and carotenoid content of D. salina. The research was conducted on March-May in the Natural  Feed Laboratory, BBPBAP Jepara Central Java. The research method was used completely randomized design. The treatments used is P0 (control) (Walne 0,5 mL/L), and P. radiates fertilizer is treatments P1 (60 mL/L), P2 (120 mL/L), P3 (180 mL/L), with 3 replicates. The density of D. salina cells is observed for ten days. Carotenoid measurement in the exponential phase using a spectrophotometer.The results showed that the P. radiatus fertilizer as a media culture gives an effect on the density and carotenoid content of D. salina. Phaseolus radiatus fertilizer showed the best density and carotenoid content at dose 60 mL/L. The amount of density in the exponential phase was 476.67 x 104 cells/mL with a carotenoid content of 0.967 µg/mL.

Abstract

Macrofungi are a nutraceutical food containing high protein, low fat, and are rich in minerals that play an important role in animal physiology, particularly as food supplements because of their distinctive aroma. This research aimed to provide information on the macroscopic and microscopic characters of several macrofungi from the Agaricomycetes consumed by animals, and to describe their antibacterial potentials. This research employed opportunistic sampling, mushroom identification and description, proximate analysis, and antibacterial assays. A total of seven mushrooms of the Agaricomycetes were described, namely Lentinus sajor-caju, Gymnopilus sp., Marasmius sp., Phallus indusiatus, Panus lecomtei, Termitomyces sp., and Schizophyllum commune. Lentinus sajor-caju had carbohydrate, fiber, protein, fat, ash, and moisture contents of 72.02%, 30.03%, 11.63%, 1.37%, 4.26 %, and 10.74%, respectively. The antibacterial assay of L. sajor-caju indicated that both 0.8 mg/ml and 1 mg/ml concentrations showed no significant difference in activity. However, both exhibited potent inhibitory effects against Candida albicans. Lentinus sajor-caju extract inhibited Enteropathogenic Escherichia coli (EPEC) at a concentration of 5 mg/ml. In comparison, a dose of 0.8 mg/ml effectively suppressed the growth of Methicillin-resistant Staphylococcus aureus (MRSA). This current research provided a basic framework for future mycophagy analysis and bioprospection in Indonesia.
