The collapse of Caribbean coral reefs has been attributed in part to historic overfishing, but whether fish assemblages can recover and how such recovery might affect the benthic reef community has not been tested across appropriate scales. We surveyed the biomass of reef communities across a range in fish abundance from 14 to 593 g m(-2), a gradient exceeding that of any previously reported fo...

Biosorption of heavy metals using dried algal biomass has been extensively described but rarely implemented. We contend this is because available algal biomass is a valuable product with a ready market. Therefore, we considered an alternative and practical approach to algal bioremediation in which algae were cultured directly in the waste water stream. We cultured three species of algae with an...

Transport time scales such as flushing time and residence time are often used to explain variability in phytoplankton biomass. In many cases, empirical data are consistent with a positive phytoplankton–transport time relationship (i.e., phytoplankton biomass increases as transport time increases). However, negative relationships, varying relationships, or no significant relationship may also be...

Biodiesel-derived glycerol is a promising substrate for mixotrophic cultivation of oleaginous microalgae, which can also reduce the cost of microalgal biodiesel. The objective of this study is to investigate the potential of using glycerol and glucose as a complex carbon substrate to produce microalgal biomass and biochemical components, such as photosynthetic pigments, lipids, soluble carbohyd...

Recently, there is increased interest in naturally produced active compounds as alternatives to synthetic substances. Although these compounds often show lower activity, they are nontoxic and do not leave residues. It has already been reflected by the projects of new law regulations in EU countries that have imposed legal restrictions on the use of xenobiotics as plant protection products or pr...

Bioplastic composite material was developed from polylactic acid used as basic polymer and microalgae. Two types of biomaterials were prepared based on the proportion microalgae acid. The mass ratios set to 5:95 10:90. First, spirulina chosen initial then a mixed culture community biogas digestate treatment. aim research study characteristics materials in order determine whether algal biomass c...
