Nitrate is the predominant form of inorganic nitrogen utilized by higher plants, fungi and algae and its assimilation forms the major pathway for production of biologically useful nitrogen. Chlorella is a unicellular eukaryotic green alga, which offers a potentially useful system for the expression of hetrologous proteins. In the present study the microalgal samples were isolated from stagnant ...

Two experiments were performed to evaluate the effect of synthetic and natural carotenoids on the daily output of eggs and some parameters of their quality. The hens were fed a control diet and diets supplemented with synthetic carotenoids Carophyll Red and Carophyll Yellow, lutein, algae Chlorella, and mustard meal. Carotenoids had no effect on hen-day egg production. Both synthetic and natura...

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 ...
