Comparison of data of protein content in algae is very difficult, primarily due to differences in the analytical methods employed. The different extraction procedures (exposure to water, grinding, etc.), protein precipitation using different amounts of 25% trichloroacetic acid and quantification of protein by two different methods and using two protein(More)
Despite decades of research on marine algae, there are still significant gaps in basic knowledge about chemical composition of these organisms, especially in tropical environments. In this study, the amino acid composition and contents of total nitrogen, phosphorus, lipid, carbohydrate and protein were determined in Asparagopsis taxiformis, Centroceras(More)
Percentages of nitrogen and phosphorus in 10 species of seaweeds (6 green and 4 red algae) were monitored from 1997 to 2004 by seasonal sampling in Guanabara Bay, South-eastern Brazil. The species did not show consistent variations in tissue N, P and N:P that related to annual cycles. Throughout this study, higher percentages of tissue N and P were found in(More)
