Effect of Some Inorganic Ions and Some Household and Industrial Wastes on The Biomass's Weight and Protein That Growth on Olive Milll Wastewater Medium

Abstract

The effect of some inorganic ions (nitrogen & phosphatase), dried domestic food residues (Fig fruit residues, Bean husks, Pea husks, Pomel husks) and some industrial wastes (Molasses - Olive sludge (solid waste of olive presses) On the weight of bio-mass developing in olive oil wastewaster OMW1, which is encrusted with Geotricum threads and extended with water extracts by 75:25 (OMW1: Aqueous extract of residues at concentration 1%,4%,7%,10%).
Nitrogen compounds had a significant effect on the increase in the mass of developing fungi compared to the control (distilled water distillation) as blank 1.0334gr/300ml dry weight where The concentration of Peas, Beans and molasses were effective at concentration (10-7), 4% and 10% respectively, with the mass increasing to 1.5346gr/300ml dry weight of Peas, 2.342gr/ 300ml dry weight of Beans and 2.5893gr/300ml of molasses. The rest of the water extracts (Phosphate compounds - Pomela husks - Fig) showed no apparent effect while sludge had a disincentive to the growth of bio-mass. (2.41g wet mushroom weight is equivalent to 0.03g dry weight) the effect of these extracts on the protein content of the biomass, Nitrogen compounds, Peas and Beans husks had a positive effect of 40% at 2.7% for Nitrogen and 30% at concentration greater than 7% for Peas and 25-20% at concentration greater than 4% For the bean extract, while the rest of the extracts (Phosphates, Pomela, Figs and Sludge) did not have any obvious effect.
