Resource partitioning of phytoplankton metabolites that support bacterial heterotrophy

Rehabilitating the cyanobacteria – niche partitioning, resource use efficiency and phytoplankton community structure during diazotrophic cyanobacterial blooms

Blooms of nitrogen-fixing cyanobacteria are recurrent phenomena in marine and freshwater habitats, and their supplying role in aquatic biogeochemical cycles is generally considered vital. The objective of this study was to analyse whether an increasing proportion of nitrogen-fixing cyanobacteria affects (i) the composition of the non-diazotrophic component of ambient phytoplankton communities a...

Therapeutic Spectrum of Bacterial Metabolites

Bacterial metabolites have been immensely useful as antibiotics, hence most of the work on the subject revolved around understanding their antibiotic properties. However, it emerged from current literature that they are pleotropic in nature as they express a broad array of activities with potential therapeutic significance. These characteristics include, but are not limited to anticancer, antiv...

Cellular partitioning of nanoparticulate versus dissolved metals in marine phytoplankton.

Discharges of metal oxide nanoparticles into aquatic environments are increasing with their use in society, thereby increasing exposure risk for aquatic organisms. Separating the impacts of nanoparticle from dissolved metal pollution is critical for assessing the environmental risks of the rapidly growing nanomaterial industry, especially in terms of ecosystem effects. Metal oxides negatively a...

Production and partitioning of organic matter during simulated phytoplankton blooms

Few studies have examined the partitioning of organic matter in upwelling systems, despite the fact that these systems play a key role in carbon and nitrogen budgets in the ocean. We examined the production and partitioning of phytoplankton-derived organic matter in deck incubations off Oregon during the upwelling season. During exponential growth of the phytoplankton, $78% of total accumulated...
