Quantification of Xylanolytic and Cellulolytic Activities of Fungal Strains Isolated from to Enhance R-Phycoerythrin Extraction of : From Seaweed to Seaweed.

R-phycoerythrin (R-PE) can be enzymatically extracted from red seaweeds such as . This pigment has numerous applications and is notably known as an antioxidant, antitumoral or anti-inflammatory agent. Enzymes secreted by associated fungal strains were assumed to be efficient and adapted for R-PE extraction from this macroalga.

Optimization of R-Phycoerythrin Extraction by Ultrasound-Assisted Enzymatic Hydrolysis: A Comprehensive Study on the Wet Seaweed .

Enzyme-assisted extraction (EAE) and ultrasound-assisted extraction (UAE) are both recognized as sustainable processes, but little has been done on the combined process known as ultrasound-assisted enzymatic hydrolysis (UAEH), and even less on seaweed. The present study aimed to optimize the UAEH of the red seaweed for the extraction of R-phycoerythrin (R-PE) directly from the wet biomass by applying a response surface methodology based on a central composite design. Three parameters were studied: the power of ultrasound, the temperature and the flow rate in the experimental system.

Data on the sensory characteristics and chemical composition of the edible red seaweed dulse () after dry and semi-dry storage.

The data article refers to the paper "Semi-dry storage as a maturation process for improving the sensory characteristics of the edible red seaweed dulse ()" [1]. The data refers to the analysis of samples of the edible seaweed species during storage in a dry (D, containing ca. 6 % moisture) and semi-dry state (SD, containing ca.

Extraction and Purification of R-phycoerythrin from Marine Red Algae.

This chapter focuses on the recovery of an R-Phycoerythrin (R-PE)-enriched fraction from marine algae. Since R-PE is a proteinaceous pigment, we have developed a simple and rapid two-step method devoted to the extraction and purification of R-PE from marine red algae. Here we describe a phosphate buffer extraction followed by anion exchange chromatography carried on a DEAE Sepharose Fast Flow column.

One-step purification of R-phycoerythrin from the red edible seaweed Grateloupia turuturu.

A one-step chromatographic method for the purification of R-phycoerythrin (R-PE) of Grateloupia turuturu Yamada is described. Native R-PE was obtained with a purity index of 2.89 and a recovery yield of 27% using DEAE-Sepharose Fast Flow chromatography with a three-step increase in ionic strength.
