To study the effect of sterols on the activity of the eukaryotic plasma membrane transporter, the hexose-proton symporter HUP1 from the unicellular alga Chlorella kessleri was expressed in Escherichia coli, a prokaryotic microorganism containing virtually no sterols. Under certain conditions, the recombinant protein was partially active in this prokaryotic organism. The heterologously produced ...
A single Brachionus rotifer can consume thousands of algae cells per hour causing an algae pond to crash within days of infection. Thus, there is a great need to reduce rotifers in order for algal biofuel production to become reality. Copper can selectively inhibit rotifers in algae ponds, thereby protecting the algae crop. Differential toxicity tests were conducted to compare the copper sensit...
This study investigates the efficacy of a prepared Ni/θ-Al 2 O 3 catalyst during pyrolytic conversion Parachlorella kessleri HY-6 and compares results with non-catalytic conversion. The was characterized by techniques such as Brunauer–Emmett–Teller (BET) for surface area, acidity, X-ray powder diffraction (XRD). Isoconversional combined kinetic methods were used to kinetics process. at 10, 20, ...
Algae are known to produce extracellular organic substances under optimum conditions and increase their production under stress. The changes in amount and composition of extra cellular carbohydrates and proteins of three green algae Scenedesmus quadricauda, Chlorella kessleri and Raphidocelis subcapitata (known as Selenastrum capricornutum) were studied after a 5-days’ cultivation under the in...
