weight 64kDa. Keywords: Phytase‚ Aspergillus fumigatus and Aspergillus terreus. INTRODUCTION Phytase is widespread in nature‚ occurring in plants‚ microorganisms‚ as well as in some animals. Microbial Phytase activity was most frequently detected in fungi. Phytic acid was discovered as early as in 1872 by Pfeffer and a first note on Phytase can be found in the literature in 1907. Phytase belongs to the group of phosphoric monoester hydrolases; it catalyzes the hydrolysis of myo-inositol hexakisphosphate

The stem is responsible for elongation of the plant and acts as a central axis for other organs to attach to. The roots help to anchor the plant as well as absorb water and nutrients from the soil. In addition‚ roots often form mycorrhizae with fungi‚ providing further advantage. Some roots are specially designed to store nutrients for later use of the plant. Leaves are wide flat regions that grow off of the stem. Their primary purpose is to add surface area for photosynthesis. 2. List the

protein and has not yet been widely adopted. Fungicides used by conservators have their problems. Thymol is toxic and banned in some places‚ orthophenyl phenol can cause health problems. Ethylene Oxide is a carcinogen so toxic to both humans and fungi (Harvey‚ 133-134). So‚ if the mold cannot be cleaned with a dry sponge or brush it is advisable to entrust it to a professional conservator to

atmosphere and are common in soils. In soil analyses‚ using dilution plate techniques‚ Penicillium species are detected with high frequency (Domsch et al.‚ 1993). However‚ very little is known of interactions between Penicillium species and other soil fungi‚ or even on plan growth. Penicillium species generally occurr at greater soil depths than species of other genera‚ and have low concentrations in rhizosphere soils (Domsch et al.‚ 1993). Some species of Penicillium are well known for their activities
