ISOLASI SENYAWA STEROID DARI TANAMAN Gynura pseudochina (Lour) DC DAN UJI AKT…
The secondary metabolites have been isolated from nonpolar fraction of methanol extract of Gynura pseudochina (Lour) DC plants. The extraction was done by maseration. Separation and purification were done by column chromatography. The isolated compound was a white solids with melting point 123 °C-125°C. The structure of this compound was determined based on spectral evidence including IR, 13C…

PRODUKSI ENZIM SELULASE DARI KAPANG Trichoderma reesei dan Aspergillus niger …
It has been conducted a research about bioethanol production from bagasse. Cellulose content in baggasse can be used as substrate in production of cellulase enzyme by using A. niger and T. reesei with solid State fermentation. It was carried out by variation of fermentation time at 27°C for 1, 3, 5 and 7 days. Concentration cellulase enzymes extract were analyzed by Lowry method. Whereas enzym…
