The aim of this study is to produce a pharmaceutical grade single cell product of Arthrospira from a mixed culture. We have designed a medium derived from a combination between George's and Zarrouk's media. Our new medium has the ability to inhibit different forms of cyanobacterium and microalgae except the Chlorella. The medium and the cultivation conditions have been investigated to map the p...

It has been found that the chemical composition of Chlorella pyrenoidosa varies over a wide range, depending on the environmental conditions selected for its growth. A description of the influence of different environmental factors on the composition of Chlorella has been given, and a method of calculating the approximate cell composition in terms of carbohydrate, protein, and lipide from the e...

It was found that the transport system for glucose (as measured by deoxyglucose uptake) in the high temperature strain of Chlorella (strain 07-11-05 or C. sorokiniana) was constitutive and the rate of uptake did not increase upon incubation of autotrophically grown cells with either deoxyglucose or glucose. The uptake obeyed Michaelis-Menten type kinetics with a concentration of 200 micromolar ...

In the present work we identified and quantified the effect of hydrodynamic stress on two different microalgae strains, Dunaliella tertiolecta and D. salina, cultivated in bench-scale bubble columns. The cell death rate constant increased with increasing gas-entrance velocity at the sparger. Dunaliella salina was slightly more sensitive than D. tertiolecta. The critical gas-entrance velocities ...

BACKGROUND In vitro and animal studies have demonstrated that Chlorella is a potent biological response modifier on immunity. However, there were no direct evidences for the effect of Chlorella supplementation on immune/inflammation response in healthy humans. METHODS This study was designed for an 8-week randomized, double-blinded, placebo-controlled trial: 5g of Chlorella (n=23) or Placebo ...

The recent discovery of the production of anti-proliferative aldehydes in a variety of microalgal species has lead to considerable investigation into the effects of these toxins on aquatic invertebrates. Studies have, however, rarely considered the impact pollutants may have on grazer responses to algal toxins. In this study, the acute toxicities of five aldehydes to the rotifer Brachionus plic...
