His parents encouraged his early interest in science, taking him to aquariums, letting him set up a chemistry lab in the bathroom, and even allowing some unwise experiments, like making rocket fuel on the stove.

Planktonic samples were collected from two habitats in Giza Governorate, Kafr Hakem (+ snails) and Sadek canals (snails). Oscillatoria accuminata and Lyngbya perelegans were collected from the first location, while Phormidium valderianum, Spirogyra sp and Lyngbya perelegans were separated from the second one. Nostoc muscorum was obtained from Theodor Bilharz Research Institute (TBRI) and used i...

Organelles from Spirogyra cells were separated on a linear sucrose gradient. After centrifugation, most of the protein was found in the top fraction. Two minor protein peaks at density (g/cm(3)) 1.17 and 1.21 were due to chloroplast particles and mitochondria, respectively. Although there was an extremely low concentration of protein at density 1.25 g/cm(3), a major part of the activity of glyc...
