The ultrastructure of dictyosomes in Scenedesmus acuminatus was studied by the freeze-substitution method. The cisternal membranes of dictyosomes clearly exhibited three-layered structures. Electron-dense particles were visible on or in the proximal cisternal membranes. The upper and lower membranes of the distal cisternae were in close contact with each other at the cisternal centre. The elect...

A pot experiment was conducted to study the influence of various irrigation regimes on some metabolic pools of wheat and alfalfa plants. The photosynthetic pigments and soluble proteins of the tested plants significantly increased when irrigated with sewage amended with Scenedesmus quadricauda or Nostoc sp. On the other hand, soluble carbohydrates decreased in wheat shoots at different treatmen...

A total of 480 Arbor Acres Broiler chicks (mixed sex) from 1 to 35 days age were divided randomly into 4 treatments evaluate the impact defatted Scenedesmus obliquus biomass (DAB) on broiler performance. The DAB was supplemented diets with levels 0, 0.25, 0.50, 1.00% one-day-old age. samples analyzed in triplicates. productive traits measured weekly and biochemical indices at end trial. Data st...

Growth intensity o f the green alga, Scenedesmus obliquus, was measured in autotrophic cultures, diluted once daily, between 20 and 30 °C in a light-dark cycle o f 16 : 8 h at initial optical densities between 0.02 and 1.2. Arrhenius analyses o f the results showed linear relationships be­ tween growth intensity and temperature below the temperature optimum. The temperature effects on growth, a...
