Biotic Factors Involued in Organic Recycling Matter Evaluating the Efficiency of Some Nanocomposites Different Paints

Abstract
The study was conducted in the laboratories of the Department of Life Sciences, College of Education for Girls. It is one of the modern studies on recycling organic waste, represented by the leaves of various plants. The treatment unit was represented by a basin for recycling plant leaves, prepared for this purpose. The recycling stages were monitored by taking samples weekly until the organic decomposition process was completed, in addition to biological tests such as measuring the vital factors represented by bacteria, fungi, and cocci bacteria participating in the decomposition and recycling process. The study demonstrated the role of microorganisms in the biodegradation process, represented by bacteria at the beginning of organic decomposition and the beginning of the decomposition of organic matter. Their percentage increased after the fourth week of the process, then gradually decreased with the end of the decomposition process and the decrease in temperature. As for fungi, their percentage was low in the fifth and sixth weeks of organic decomposition, but at the beginning of the decomposition process they were present but in large numbers. Bacillus bacteria appeared at the beginning of the organic decomposition process and appeared in large numbers at the beginning of the fourth week of the process, and the percentage decreased in the sixth and seventh weeks of the organic decomposition process with the decrease in temperature. As for the organic matter, its percentage was measured from the beginning of decomposition until the end of the decomposition.
