“…Higher concentrations of the photosynthetic pigments chlorophyll a and phycobiliproteins were registered in algae grown at 20 cm. This result is in agreement with previous studies (Eswaran et al 2002;MarinhoSoriano 2012;Pereira et al 2012), which also observed an increase in the pigment concentration associated with a decrease in irradiance. This increment in pigment concentration is related to an increase in the size of the light-harvesting complex and the number of photosystems, resulting in an amplified ability to collect incident light and convert it into energy.…”

“…These two components play an important role in nitrogen storage, and are the primary pools of metabolized nitrogen when environmental nitrogen concentrations are reduced. Moreover, the fact that the red strain synthesizes more phycoerythrin makes it more competitive in capturing solar energy and performing photosynthesis (Pereira et al 2012). This ability contributes to higher growth and thus better environmental performance.…”

“…G. domingensis is characterized by red, green, and brown phenotypes in natural populations (Pereira et al 2012). This study aimed to evaluate the intraspecific differences of three color variants of G. domingensis in biomass yield, growth, and pigment by culturing them in a shrimp pond, an integrated organic system.…”

Species of the genus Gracilaria are widely distributed around the world, and many are wild harvested and cultivated for phycocolloid production (agar) and human food. This study investigated the growth performance of three color strains of Gracilaria domingensis in an integrated organic system. The three chromatic variants (red, green, and brown) were cultured in a shrimp farm at two depths (surface and 20 cm). The highest relative growth rates were obtained in the first week of cultivation for all three strains studied. Although the growth rates and biomass were slightly higher at a depth of 20 cm, significant differences were not observed at different depths (p \ 0.05). The growth of the three strains varied significantly over time (p \ 0.001). The maximal growth values obtained were 11.25 ± 1.50% day -1 (red), 12.76 ± 3.96% day -1 (green), and 7.86 ± 1.75% day -1 (brown). The mean growth rates for the whole period were 4.63 ± 6.97, 3.38 ± 9.09, and 2.16 ± 6.61% day -1 for the red, green, and brown strains, respectively. The pigment content (chlorophyll a, phycocyanin, and phycoerythrin) of the three strains studied was higher at a depth of 20 cm, while the maximum electron transport rate (ETR max ) and photosynthetic efficiency were higher at the surface. The high growth rates obtained in this study demonstrate the great potential of this species for integrated organic farming. Moreover, the ecological success shown by the red strain suggests that this strain is the most suitable for integrated cultivation.

“…Phycoerythrin content in Gloiopeltis furcate (Postels et Ruprecht) J. Agardh, and Porphyra yezoensis Ueda correlated significantly with nitrogen content (Mizuta et al 2002). Pereira et al (2012) found that nitrate was assimilated as PC and PE by Porphyra dioica Brodie and Irvine and phycoerythrin PE was the main form of nitrogen pool, while, phosphorus participates in the formation of biomolecules such as nucleic acids, proteins and phospholipids. In the same year, Marinho-Soriano (2012) showed the importance of NO 3 for the biosynthesis of this pigment, demonstrated the positive correlation between them.…”

“…Both PE and PC concentrations showed clear trends of decreasing concentration with increasing temperature (Latham 2008). Pereira et al (2012) stated that the concentration of R-Phycoerythrin (RPE) and Chl-a in Gracilaria bursapastor is showed maximum values in the winter and minimum values in summer.…”

Resumen.-Se investigaron los cambios estacionales en la composición de pigmentos [Clorofila a (Cl-a), carotenoides totales (Car.), ficobiliproteínas (ficoeritrina (PE), ficocianina (PC), aloficocianina (APC))], en 5 especies de Rhodophyta. Los niveles de clorofila a, carotenoides y ficobiliproteínas presentaron altos contenidos durante invierno, y disminuyeron en verano, mostrando decoloración de tejidos de rojo a verde o amarillo. Los resultados muestran que los contenidos de pigmentos variaron estacionalmente con respecto a las especies de algas, y a los cambios de los parámetros físico-químicos, mientras que el pH, oxígeno disuelto, NO 3 -, NO 2 -, NH 4 + , nitrógeno total (TN) y fósfato total (TP) tuvieron un impacto directo sobre el contenido de pigmentos fotosintéticos, y la temperatura tuvo una correlación negativa significativa sobre los pigmentos fotosintéticos. Palabras clave: Parámetros ambientales, clorofila, ficobiliproteínas, algas rojas, variación estacionalAbstract.-Seasonal changes of pigment composition [Chlorophyll a (Chl-a), total carotenoid (Car.), phycobiliproteins (phycoerythrin (PE), phycocyanin (PC), allophycocyanin (APC))], in the 5 species of Rhodophyta were investigated. Chl-a, carotenoids and phycobiliproteins levels showed high contents during winter, whereas decreased in summer showing discoloration tissue from deep red to green or yellow. The results show that the pigment contents were varied seasonally with respect to the algal species and physical and chemical parameters changes, while pH, dissolved oxygen, NO 3 -, NO 2 -, NH 4 + , total nitrogen (TN) and total phosphorus (TP) had direct impact on photosynthetic pigments content, and temperature had significant negative correlation on photosynthetic pigments.
