Whole Cells from a Red Alga, Galaxaura falcata*1
نویسندگان
چکیده
Photoactive whole cells were isolated for the first time from a red alga, Galaxaura falcata KJELMAN, of the Chaetangiaceae. By means of proton uptake experiments, its optimum irradiation ntensity required for photosynthesis, effec of Ca2+, Mg2+, Mn2+ and Na+ both mono-and divalent ions, uncouplers and a non-ionic surfactant were examined. Photochemical 14CO2 fixation u der different monochromatic irradiation , and RuDP and PEP carboxylase activities n the cells were also studied and compared with those of thallus extracts. These results demonstrated the isolated cells to be biochemically active. An electron microscope study of the isolated whole cells was also performed.

Variability in grazer-mediated defensive responses of green and red macroalgae on the south coast of South Africa
Variabilities in the responses of several South African red and green macroalgae to direct grazing and the responses of one green alga to cues from grazers were tested. We used two feeding experiments: (1) testing the induced responses of three red and one green algae to direct grazing by mesograzers and (2) a multi-treatment experiment, in which the direct and indirect effects of one macrograz...
متن کاملMacroalgal terpenes function as allelopathic agents against reef corals.
During recent decades, many tropical reefs have transitioned from coral to macroalgal dominance. These community shifts increase the frequency of algal-coral interactions and may suppress coral recovery following both anthropogenic and natural disturbance. However, the extent to which macroalgae damage corals directly, the mechanisms involved, and the species specificity of algal-coral interact...
متن کاملAntiherpes virus effect of the red marine alga Polysiphonia denudata.
The water extract from the red marine alga Polysiphonia denudata (Dillwyn) Kutz. from the Bulgarian Black Sea coast selectively inhibited the reproduction of herpes virus type 1 and type 2 in cell cultures (EC50=8.7 to 47.7 mg/ml) as shown by the reduction of virus-induced cytopathic effect and viral infectivity. The virus-inhibitory effect was dose-related, strain-specific and depended on viru...
متن کاملDetection and Enhancement of Ketocarotenoid Accumulation in the Newly Isolated Sarcinoid Green Microalga Chlorosarcinopsis PY02
The sarcinoid alga PY02 is a newly isolated soil alga native to western Thailand. In this study PY02 is described, the carotenoid profile of the green and red forms of the algal cells are compared, and the effect of nitrogen reduction and media volume on ketocarotenoid production are reported. Partial sequences of the genes from elongation factor Tu (tufA) and 18S rRNA reveal that the alga is f...
متن کاملIsolaurenidificin and Bromlaurenidificin, Two New C15-Acetogenins from the Red Alga Laurencia obtusa.
Chromatographic fractionation of the CH₂Cl₂/MeOH extract of the Red Sea red alga Laurencia obtusa gave two new hexahydrofuro[3,2-b]furan-based C15-acetogenins, namely, isolaurenidificin (1) and bromlaurenidificin (2). The chemical structures were elucidated based on extensive analyses of their spectral data. Compounds 1 and 2 showed no toxicity (LC50 > 12 mM) using Artemia salina as test organi...
