It has been reported that 1g of soil when plated,
harbours up to 10 billion microorganisms, of which about 4.2 × 106 CFU/g (dry weight) are accounted for by bacteria species[6]. The number of actinomycetes (3.5 × 105 CFU/g dry soil) obtained in this study was however lower than expectation. This may be partly attributed to the geographical location of the soil. As indicated in the methodology, the soil was collected from an area that was relatively steep and not quite in the shade. The steepness of the terrain, exposure to the sun rays and lack of vegetation covering of the soil (bare) may have caused leaching of actinomycetes and therefore have partly contributed to the observed low actinomycetes CFU/g of dry soil.
