t discoveries on controls that direct the metabolism of algal cells towards starch hyper-accumulation with the aim of providing starch-enriched biomass for the production of bioethanol as a biofuel of the future. We also outline basic research from the 1960s, from which the recent starch research st

Mahmoud Sakr,Ibrahim Fathiproduce biomass and valuable chemicals through biorefinery processes. Supplementing microalgae cultures with organic carbon sources increase the biomass production and lipid/carbohydrate contents in cells. Consequently, this yields high productivity of biorefined products such as biodiesel, ethanol,

Mahmoud Sakrent of oxygenic photosynthesis 2.5–2.7 billion years ago (Holland 1984) led to drastic chemical changes in the Earth’s oceans and atmosphere. The gradual increase in photosynthetically produced oxygen over millions of years was accompanied by a strong enrichment of it in the atmosphere, which ultima

Tarek Koraitimoxyproline. In animal cells, a large family of well characterized hydroxyproline-rich glycoproteins (HRGP’s), the collagens, perform a variety of important structural, developmental, and homeostatic functions. That plants also contain HRGP’s was first demonstrated by D.T.A. Lamport (1), who named th
