Polymeric alkylpyridinium salts (poly-APS) isolated from the marine sponge Reniera sarai act as antifouling and anticholinesterase agents. They also show moderate haemolytic and cytotoxic activities against different cell lines. The haemolytic activity of poly-APS is due to their detergent-like structure and behaviour in aqueous solutions. In this work, the lytic activity of poly-APS against fr...

Anaerobic degradation of marine algae, seagrass and tropical climbing vines to produce a renewable energy source and the analysis of their anaerobic microbial communities Report Title Energy demand by contemporary societies and the excessive consumption of fossil fuels have impulsed research and the employment of renewable energy systems. It has been proposed, in terms of renewable systems, the...

Cyanobacteria (blue-green algae) are abundant in fresh, brackish and marine waters worldwide. When toxins produced by cyanobacteria are present in the aquatic environment, seafood harvested from these waters may present a health hazard to consumers. Toxicity hazards from seafood have been internationally recognised when the source is from marine algae (dinoflagellates and diatoms), but to date ...

Sulfolipids were originally discovered in diatom species, in 1966, by Morris Kates [1–3]. High levels of these sulfolipids have been found in the alga Ochromonas danica (Chrysophyceae, Chrysophyta) where they constitute 15% of total lipids and 3% of the dry weight of heterotrophically grown, stationary-phase cells [4,5]. More recently, sulfolipids have also been identified in more than 30 speci...

The marine environment is home to a taxonomically diverse ecosystem. Organisms such as algae, molluscs, sponges, corals, and tunicates have evolved to survive the high concentrations of infectious and surface-fouling bacteria that are indigenous to ocean waters. Both macroalgae (seaweeds) and microalgae (diatoms) contain pharmacologically active compounds such as phlorotannins, fatty acids, pol...
