Furthermore, Spirulina contains many functional bioactive ingredients with antioxidant and anti-inflammatory activities, including phenolic phytochemicals [25,26] and the phycobiliprotein
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., 2007).
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).
The Impact on the Content of Phycobiliprotein
of Algae Cells.
It has the solar energy utilization efficiency up to 18% and the photosynthetic efficiency up to 43% (more than 3 times high to those of advanced plants) due to its phycobiliprotein
. So this paper intended to extract phycobiliprotein
from spirulina and used it as photosensitizer to sensitize nano-Ti[O.sub.2] to equip the dye sensitized solar cell .
Several reports have presented data of photosynthetic yield in cyanobacteria by using different excitation light wavelengths as orange (590 nm) for chlorophyll-a fluorescence induction (FI) kinetics using a FL-100 Fluorometer (Photon Systems Instruments, Czech Republic) (Kana et al., 2009) or blue light avoiding the excitation of phycobiliproteins
(since the cellular phycobiliprotein
content influences the [F.sub.0] level fluorescence, particularly when phycobiliprotein
levels are high).
conjugates for analyses of cells and molecules.

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.
