on glucose, sucrose and sugarcane molasses for phycobiliprotein
In our case, possibly IAA separated pigments by hydrophobic interaction with N-H groups of the proteins and by low relatively density of this solvent compared with water (LIDE, 1998) (Figure 2), especially phycoerythrin, a red protein-pigment complex from the light-harvesting phycobiliprotein
family, which is easily extracted from Rhodophyceae, in which it play an important protective role against oxidative damage provoked by excess light exposure, and have several biotechnological applications for various fields, including food, medicine and aquaculture (CARDOZO et al.
On the other hand, PC is a phycobiliprotein
of large dimensions (121,000 Da in its trimeric form, and approximately 40,000 Da in its monomeric form).

content influences the [F.

Key Words: Antioxidant activity; Cyanophyceae; N-terminal analysis sequence; Phycobiliprotein

It also contains a unique blue pigment, phycobiliprotein
, which is only found in blue-green algae," said Gerald Cysewski, PhD, founder and chief science officer, Hawaii-based Cyanotech.
Immunoassay techniques with fluorescent phycobiliprotein
complex while still retaining genes encoding the phycobiliprotein
In contrast to green algae, cyanobacteria contain phycobiliprotein
2009; Dembitsky and Rezanka 2005), also produced of phycobiliprotein
pigments (Czeczuga et al.
The presence of the phycobiliprotein
phycocyanin was confirmed by the fluorescence method of Stewart & Farmer (1984), thereby placing the isolate unequivocally in the cyanobacteria; this fluorescence spectrum was identical to that of Synechococcus sp.
