Bioethanol a by-product of agar and carrageenan production industry from the tropical red seaweeds, Gracilaria manilaensis and Kappaphycus alvarezii
The two red seaweeds, Gracilaria manilaensis and Kappaphycus alvarezii are cultivated in Malaysia for producing agar and carrageenan, respectively. The residues of these seaweeds after removing agar and carrageenan by dilute acid treatment were subjected to enzymatic hydrolysis using cellulase (Cellic CTec 2). In the optimization of enzymatic hydrolysis, highest glucose concentration was achiev...
متن کاملChemical analysis and biorefinery of red algae Kappaphycus alvarezii for efficient production of glucose from residue of carrageenan extraction process
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...
متن کاملKappaphycus alvarezii as a Food Supplement Prevents Diet-Induced Metabolic Syndrome in Rats
The red seaweed, Kappaphycus alvarezii, was evaluated for its potential to prevent signs of metabolic syndrome through use as a whole food supplement. Major biochemical components of dried Kappaphycus are carrageenan (soluble fiber ~34.6%) and salt (predominantly potassium (K) 20%) with a low overall energy content for whole seaweed. Eight to nine week old male Wistar rats were randomly divided...
متن کاملMolecular identification of the exotic lineage of Kappaphycus alvarezii (Rhodophyta, Solieriaceae) cultivated in the tropical region of Brazil
Kappa carrageenan is an important phycocolloid extracted from the red seaweed Kappaphycus alvarezii. This species has been introduced into several regions, most recently in Brazil. The remote invasive potential of this seaweed in both south and southeast waters of Brazil (subtropical regions) has been established, but introduction in the northeastern tropical area is contested due to the absenc...
متن کاملThe introduced alga Kappaphycus alvarezii (Doty ex P.C. Silva, 1996) in abandoned cultivation sites in Bocas del Toro, Panama
The red alga Kappaphycus alvarezii (Doty ex P.C. Silva, 1996) has been intentionally introduced throughout the tropics for mariculture. In some cases, the alga has spread outside cultivation sites and impacts native biota. We conducted surveys of two sites in Bocas del Toro, Panama, where non-native K. alvarezii was previously cultivated to determine whether it is established and began to exami...
