BACKGROUND Biorefineries serve to efficiently utilize biomass and their by-products. Algal biorefineries are designed to generate bioproducts for commercial use. Due to the high carbohydrate content of algal biomass, biorefinery to generate biofuels, such as bioethanol, is of great interest. Carrageenan is a predominant polysaccharide hydrocolloid found in red macroalgae and is widely used in f...

Seaweed liquid fertilizers (SLFs) contain macronutrients, micronutrients and trace nutrients essential for microalgal growth. The study aims to evaluate the efficiency of SLFs on biomass production, biochemical physiological processes; was carried out at different SLF concentrations selected seaweeds i.e. Kappaphycus alvarezii, Gelidiella acerosa Turbinaria ornata. comparative analysis growth p...

Kappaphycus alvarezii is kind of red seaweeds that can be cultivated to produce carrageenan. Fishermen in Kolorai Island South Morotai are this seaweed. A number studies show the quality carrageenan was determined by length times cultivation and coastal chemical physics parameter. The purpose study determine influence harvesting on different time characteristic ATC flour. Random design complete...
