Enzymatic characteristics of ligninperoxidases from Penicillium citrinum, Fusarium oxysporum and Aspergillus terreus using n-propanol as substrate.

چکیده
The activities of ligninperoxidases from Penicillium citrinum MTCC 3565, Fusarium oxysporum MTCC 3379 and Aspergillus terreus MTCC 3374 have been assayed and the enzymatic characteristics like Km, pH and temperature optima using n-propanol as the substrate have been reported. The results suggest that n-propanol can substitute veratryl alcohol as substrate for assaying ligninperoxidase activities from different fungal strains, without affecting the enzymatic characteristics. The above strains were selected, as they were known to secrete ligninperoxidase in the liquid culture medium.

Screening of Microfungi from Soybean (glycine Max L.) Seeds
Seed health testing by studying the seed-borne fungi of soybean seeds is an important step in the management of the seed-borne diseases. In the present study seed-borne fungi was studied by using agar plate method. A number of seed-borne fungal species was isolated from the agar plate. These seed-borne fungal sps. were Aspergillus niger, A. flavus, A. fumigatus, Chaetomium globosum, Curvularia ...

Chitosan (CS)-g-poly (acrylic acid) (PAA) nanoparticles, which are well dispersed and stable in aqueous solution have been prepared by template polymerization of acrylic acid in chitosan solution. The prepared CS-PAA had a white powder shape and was insoluble in water and diluted acid. The mean particles size were found to be around 50nm. FTIR spectra of CS-PAA nanoparticles for CS, the intensi...
