The primary requirements for high-biomass-concentration microalgal cultivation include a photon source and distribution, efficient gas exchange and suitable growth medium composition. However, for mass outdoor production of microalgae, growth medium composition is a major controlling factor as most of the other factors such as light source and distribution are virtually uncontrollable. This wor...

the aim of the present study was to isolate cyanobacteria from oil refinery waste water and detection of antagonistic activity of their extracts on four species of pathogenic bacteria. the cyanobacterium was isolated and purified on blue green algae medium number 11 (bg-11) medium. methanol and water extracts prepared from the cultured cyanobacterium after 45 days growth on bg-11 medium. the bi...

Cellulase production by the fungus Trichoderma reesei was studied using sugar beet pulp (SBP) as a substrate. The subculture medium was a salt solution consisting of KH2PO4, CaCl2, etc. Fungal cells were sub-cultured in an orbital shaker (180 rpm) at 30°C for 1-2 generations (two days for each generation) and were then used as an inoculum. Exponential cells were inoculated into a medium contain...

Escherichia coli is routinely used for the production of recombinant proteins both for research purposes and for commercial applications. Despite the extensive amount of knowledge gathered about the synthesis and accumulation of heterologous proteins and the well established principals affecting the production of secondary metabolites, little attention has been paid to the effects of medium com...
