Comparative study of some chemical and physical properties of fungi filterates isolated from sclerotia of Sclerotinia sclerotiorum (Lib.)de Bary and Trichoderma harzianum.


Series of lab. Experiments were conducted in the laboratories of Biol. Dept.College of Education for pure Science ,Kerbala University . Some Chemical and physical properties of fungi filtrates isolated from sclerotia represented by Aspergillus niger , A. terreus and Penicillium sp. and Trichoderma. harzianum filtrate were studied . Results revealed variated numbers of Rf ranged between 0.06 and 0.91 in addition to the variation in the number of spots on TLC plates.Extracts pH which tend to the acidity was also studied . The study showed a presence of some active chemicals compounds as alkaloids and the absence of some chemical compounds such as Flavonoids
