Microcalorimetry was used to show that transition-temperature ranges of phospho- and glycolipids of the brown marine alga Laminaria japonica were similar (from -62 to -47 degrees C up to 62-65 degrees C), except for monogalactosyldiacylglycerol, the low-temperature limit of which was shifted to -78 degrees C. As was shown by polarizing microscopy, the low-enthalpy peaks at temperatures of appro...

The heterokont benthic multicellular algae Schizocladia ischiensis E.C. Henry, K. Okuda et H. Kawai (Schizocladiophyceae), Hecatonema terminale (Kützing) Kylin and Striaria attenuata (Greville) Greville (Phaeophyceae) are reported for the first time from waters around Maltese islands in central Mediterranean. They were identified through algal isolation incubated natural substrata, coupled with...

The coastal water of Aboru village is one site with high diversity marine biological resources such as brown algae. purpose this study was to determine the morphological character algae Turbinaria from Village. procedure consists field collection, and observations in laboratory. characters observed were presence/absence rhizoid/holdfast, cauloid/stipe, phylloid/blades, pyrenoid/vesicle (air bub...

in this research, the batch removal of toxic hexavalent chromium ions from wastewater and aqueous solution using dried (bd) sargassum sp. (brown marine algae) and activated carbon (ac) prepared from it was examined. biomass, ph and the initial concentration of cr(vi), adsorption models and kinetic studies were investigated. the experiment was performed in a batch system and theeffect of solutio...

nowadays, organic fertilizers play an important role in agriculture. they are progressively substituting chemical fertilizers to prevent their harmful impact on human health and the environment. they provide high yield, better quality products and a shorter period of harvesting crops. in this study, the mineral elements: primary macronutrient (n, po3- and k+), secondary macronutrient: (ca2+, mg...

Research on natural products from marine algae has increased dramatically since last few decades. Marine natural products provide a rich source of chemically diverse compounds which have significant potential to be developed as novel types of therapeutic agents. Certain marine products diverse in biological and therapeutic potential have been found to exhibit significant antimicrobial effects a...

Fucoxanthin is the main carotenoid produced in brown algae as a component of the light-harvesting complex for photosynthesis and photoprotection. In contrast to the complete elucidation of the carotenoid biosynthetic pathways in red and green algae, the biosynthetic pathway of fucoxanthin in brown algae is not fully understood. Recently, two models for the fucoxanthin biosynthetic pathway have ...
