Production of Bioethanol From Kappaphycus alvarezii Algae by Using Pichia kudriavzevii Yeast

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...

Analysis of Bioactive Compounds and Antimicrobial Activity of Marine Algae Kappaphycus Alvarezii Using Three Solvent Extracts

The seaweeds are economically valuable resources, used as food, fodder, fertilizer and medicine and thus useful to mankind in many ways. In the present study, Kappaphycus alvarezii, a marine alga, has been analysed for the presence of bioactive products using three solvent extracts. Antimicrobial activity was also done using the same extracts of seaweed. The results revealed that the selected s...

Chemical 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...

An Overview of Bioethanol Production From Algae

Changes of Photosynthetic Behaviors in Kappaphycus alvarezii Infected by Epiphyte

Epiphytic filamentous algae (EFA) were noted as a serious problem to reduce the production and quality of K. alvarezii. The morphological studies revealed that the main epiphyte on K. alvarezii was Neosiphonia savatieri in China. Though the harmful effects of EFA on the production of K. alvarezii have been reported, the detailed mechanism of the N. savatieri in limiting the production of K. alv...
