We investigated feeding of natural populations of red-tide algae, heterotrophic nanoflagellates (HNFs), and ciliates (<30 μm in cell length) on natural populations of marine bacteria (mostly heterotrophic bacteria) in diverse Korean waters (Masan Bay, Jinhae Bay, Shiwha Bay, Keum River estuary, and the open coastal waters off Yeosu) during red tides in 2004 to 2005. To explore the functional re...

agar is a gelling biopolymer that can be extracted from cell wall of some red algae. in this present, response surface methodology was used to investigate the procedure of agar melting point and gelling temperature from cultural algae of gracilariopsis persica. independent variables, alkalinity concentration (2, 3.2, 5, 6.8, -8%), extraction temperature (90, 96, 105, 114, 120°c) and extraction ...

and an increased chlorophyll b to chlorophyll a ratio for better light capture in low light. Furthermore, an Ostreobium strain living in a coral skeleton, where nearly all of the red light has been captured by the zooxanthellae in the coral tissue, has been shown to have modified chlorophyll with a spectrum shifted towards far-red wavelengths. As zooxanthellae cannot use far-red light, more of ...

What are algae? Algae organisms that perform photosynthesis; is, they absorb carbon dioxide and release oxygen (therefore have chlorophyll, a group of green pigments used by photosynthetic convert sunlight into energy via photosynthesis) live in water or humid places. great variability divided microalgae, small size only visible through microscope, macroalgae, which larger size, up to more than...

Different solvent extracts of a red algae, Hypnea flagelliformis,and two brown algae, Cystoseira myrica and Sargassum boveanum, collected from the Persian Gulf coast were subjected to different bioassays including: 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay, antibacterial and antifungal activity by thin layer chromatography (TLC)-bioautography, agar disc diffusion (ADD) ...
