Our results show the natural production of two olefins, trichloroethylene and perchloroethylene, by various marine macroalgae a microalga. We found significant difference in ability algae to produce these compounds. The rates for varied between 0.022 3,400 ng g ‒1 fresh wt (FW) h were generally higher than those perchloroethylene (0.0026–8.2 FW ). subtropical algae, Asparagopsis taxiformis Falkenbergia hillebrandii , showed highest formation rates. One axenic red microalga, Porphyridium...
Article Agar Composition as a Function of Morphology and Growth Rate. Studies on Some Morphological Strains Gracilaria secundata verrucosa (Rhodophyta) was published January 1, 1989 in the journal Botanica Marina (volume 32, issue 3).

Peroxisomes are organelles that crucial for cellular metabolism, but they also play important roles in non-metabolic processes such as signalling, stress response or antiviral defense. To uncover the consequences of peroxisome deficiency, we compared Saccharomyces cerevisiae wild-type with pex3 cells, which lack peroxisomes, employing quantitative proteomics and transcriptomics technologies. Cells were grown on acetate, a carbon source requires peroxisomal enzymes glyoxylate cycle to...

Article The Influence of Photon Irradiance, Day Length, Dark Treatment, Temperature, and Growth Rate on the Agar Composition Gracilaria sordida W. Nelson verrucosa (Hudson) Papenfuss (Gigartinales, Rhodophyta) was published January 1, 1990 in journal Botanica Marina (volume 33, issue 6).
High yields of protoplasts (105-107 g1 fresh weight) from four species Gracilaria were released by enzymatic degradation the cell wall. The effects different enzymes at concentrations, varying pre-cultivation conditions, and osmolality enzyme solution on algal protoplast tested. Large numbers G. lemanaeformis in 10 13 tested mixtures all growth rates. Virtually no sordida tenuistipitata unless plants cultivated a permissive rate. yield was also influenced solution.

Article The Effect of Salinity Changes on the Activity α-Galactosidase Red Algae Gracilaria sordida and G. tenuistipitata was published January 1, 1990 in journal Botanica Marina (volume 33, issue 5).
The alkali treatment used previous to agar extractions from the Gracilaria genus reduces, among other reactions, sulphate content and improves gel strength; however, at an industrial level it requires expensive effluent processing reduce its polluting charge. red alga cornea was cultivated under dark salinity treatments replace this treatment. different tested were: (a) darkness 33‰ for 8 days, [dark treatment]; (b) 50‰ 4 followed by 25‰ [4+4]; (c) [8+4]. [4+4] increased yield in 26% (from...
An α-galactosidase (α-galactopyranoside galactohydrolase, EC 3.2.1.22) has been isolated from the red seaweeds Gracilaria tenuistipitata Zhang et Xia China and sordida W. Nelson New Zealand, its properties have investigated. The enzyme displayed high activity towards p-nitrophenyl-α-D-galactopyranoside fioridoside (O-α-D-galactopyranosyl-(1–2)-glycerol), low isofioridoside (O-α-D-galactopyranosyl-(1-1)-glycerol). It showed little melibiose, raffinose other glycosides tested. enzymes G. had...
Peroxisomes are ubiquitous cell organelles involved in various metabolic pathways. In order to properly function, several cofactors, substrates and products of peroxisomal enzymes need pass the organellar membrane. So far only a few transporter proteins have been identified. We analysed membrane fractions purified from yeast Hansenula polymorpha by untargeted label-free quantitation mass spectrometry. As expected, known peroxisome-associated were enriched fraction. addition, other enriched,...
Abstract Peroxisomes are organelles that crucial for cellular metabolism. However, these play also important roles in non-metabolic processes, such as signalling. To uncover the consequences of peroxisome deficiency, we compared two extremes, namely Saccharomyces cerevisiae wild-type and pex3 cells, which lack functional peroxisomes, employing transcriptomics quantitative proteomics technology. Cells were grown on acetate, a carbon source involves peroxisomal enzymes glyoxylate cycle does...
