Seaweed is a biological resource that rich in nutrients and bioactive compounds. This study aims to determine qualitatively quantitatively the compounds (flavonoids, alkaloids, steroids/terpenoids, saponins phenols) from extracts fractions of Eucheuma cottonii. The method used an experiment by conducting series experiments extracting fractionating E. cottonii data were analyzed descriptively. t...

The transport of alcohols was studied in Corynebacterium acetophilum, which was isolated as a strain growing well on acetate and ethanol. The transport of ethanol was found to be inducible by ethanol, n-propanol, n-butanol, and acetate, whereas transport of methanol occurred by noninducible passive diffusion. The entry of ethanol into the cells occurred against a concentration gradient and show...
