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...

This study aimed to evaluate the abilities of plant and algae lectins to inhibit planktonic growth and biofilm formation in bacteria and yeasts. Initially, ten lectins were tested on Staphylococcus epidermidis, Staphylococcus aureus, Klebsiella oxytoca, Pseudomonas aeruginosa, Candida albicans, and C. tropicalis at concentrations of 31.25 to 250  μ g/mL. The lectins from Cratylia floribunda (CF...

BACKGROUND The biosynthesis of metal nanoparticles by marine resources is thought to be clean, nontoxic, and environmentally acceptable "green procedures". Marine ecosystems are very important for the overall health of both marine and terrestrial environments. The use of natural sources like Marine biological resources essential for nanotechnology. Seaweeds constitute one of the commercially im...

St. Martin’s Reef (SMR) about 14 km west of the Island, Teknaf, Cox’s Bazar, Bangladesh was not known during last over 50 years seaweed researches. Recent six collections made with assistance Navy revealed 8 seaweeds species which are Pterocladiella maribagoensis Boo and Geraldo, Hypnea spinella (C. Agardh) Kützing, Peyssonnelia polymorpha (Zonars.) Schmitz, Jania pumila Lamx., ungulata f. brev...

This study analyzed the fatty acids composition and their profile qualitatively quantitatively of nine abundant macroalgal specimens collecting from Egyptian coasts. GC mass analysis identified 23 types, including 13 saturated (SFA) 10 monounsaturated (MUSFA). SFA dominated with 78%, while MUFAs had 22%, UFAs were negligible at 0.01%. MUSFA oleic acid (omega-9) was present in all species except...

Seaweeds are one of the most potential aquaculture commodities in Bangladesh. It has a long back history being used for its nutritional and pharmaceutical importance. This review summarizes seaweeds diversity culture, distribution possible applications uses Seaweed floras distributed along entire coastline, however, higher abundance these have found St. Martin Island, Cox's Bazar, Sundarbans ma...

Abstract. Regulation of tissue water potential is a key mechanism in macroalgal osmotic responses to changing external conditions, which are common tidally influenced estuarine and intertidal systems. Nevertheless, significant knowledge gaps exist our understanding macroalgae because few methods measure within tissues. Leaf psychrometers have furthered potentials terrestrial plant relations, ye...
