Inhibition of Freshwater Algal Growth Using Photocatalyst

Linking algal growth inhibition to chemical activity

Improving Photobioreactor wall Using Optical Brightener: Investigating the Photostability of Coated Layer and Algal Growth

In this work, photostability, absorption and emission intensity of coated polycarbonate (PC) sheets with optical brightener (OB) as a wavelength converter material have been investigated. In addition, this coated sheet was used as a wall for microalgae culture flask, as a small scale photobioreactor, for studying the spectral conversion of UV-A radiation to blue light region and its effect ...

Effects of Nano-Titanium Dioxide on Freshwater Algal Population Dynamics

To make predictions about the possible effects of nanomaterials across environments and taxa, toxicity testing must incorporate not only a variety of organisms and endpoints, but also an understanding of the mechanisms that underlie nanoparticle toxicity. Here, we report the results of a laboratory experiment in which we examined how titanium dioxide nanoparticles impact the population dynamics...

Monitoring of Algal Growth Using their Intrinsic Properties

The increasing cost of fuel, as well as the impact of climate change, has dramatically increased the interest in alternative fuel sources. Biofuel production from algae is an area of keen on-going research. A key element in this research involves monitoring algal growth under a variety of conditions over time. Here we describe the use of the SynergyTM H4 Multi-Mode Microplate Reader to monitor ...

EFFECTS OF WOOD ON THE GROWTH OF LIGNICOLOUS FRESHWATER FUNGI

The addition of cottonwood and ash sapwood powder to YPSSl2 medium influenced the mycelial growth of 13 species of freshwater lignicolous Ascomycetes and Hyphornycetes. These species fall into three groups with respect to their responses to the presence of leached or non-leached wood powder. Neither wood type showed strong inhibitory effect on the mycelial growth of the species. Leaching di...
