The new trend in using photosynthetic microorganisms for the epuration of wastewater in recirculating aquaculture systems (RAS) opens a new question concerning the economic significance of this newly synthesized biomass. In this paper, we present our

In Recirculating Aquaculture System (RAS) the water effluent from fish tanks is reused after cleansing mainly with respect to organic substances, nitrate (NO3 -), nitrite (NO2 -), ammonium (NH4 +) and phosphate (PO4 -3) ions. One of the most used and

Auriferous sulphide ores often incorporate micro-fine (or invisible) gold and silver particles in a manner making their extraction difficult. Nobel metals are lost in the tailings due to the refractory nature of these ores. Bioleaching is an environm

Magnetotactic bacteria (MTB) cells contain chains of magnetosomes, which are magnetite nanocrystals enveloped in a lipid bilayer. A water-based suspension of cultured MTB was prepared and the electric and magnetic properties were measured by two meth
