Exoglucanase was produced using coffee husk, the by-product of coffee processing industries, as the sole carbon source using economical fermentation strategies like solid-state fermentation (SSF). The effects of process parameters such as pH, moisture and fermentation duration on exoglucanase synthesis was investigated using response surface methodology (RSM) based on three factors and five lev...

The poppy of Argemone Mexicana are high in protein, carbohydrates, lipids and minerals. They are also rich in novel alkaloids, and sterols The poppy of Argemone species contain a high concentration of berberine and sanguinarine alkaloids The alkaloids of argemone are widely used as Analgesic; Antispasmodic; Demulcent; Emetic; Expectorant; Hallucinogenic; Purgative; Sedative; Skin; WartsThe root...

A method is described to discriminate between live and dead cells of the infectious fungi Aspergillus fumigatus, Aspergillus flavus, Aspergillus terreus, Mucor racemosus, Rhizopus stolonifer and Paecilomyces variotii. To test the method, conidial suspensions were heat inactivated at 85 degrees C or held at 5 degrees C (controls) for 1 h. Polycarbonate filters (25 mm diameter, 0.8 microm pore si...

Aqueous and ethanolic extracts of duckweed (Lemna pauciscostata) meal was tested on fungal isolates from stored pelleted fish feeds to ascertain its efficacy as an antifungal agent against feed spoilage fungi. Test organisms used were Fusarium oxysporium, Penicillium digitatum, A. niger, A.flavus, A.fumigatus, Rhizopus oryzae and .stolonifer .Phytochemical analysis of the crude extract was also...

The fungal flora decomposing rice straw were investigated all over the soil of Sharkia Province, east of Nile Delta, Egypt, using the nylon net bag technique. Sixty-four straw-decomposing species belonging to 30 genera were isolated by the dilution plate method in ground rice straw-Czapek's agar medium at pH 6. The plates were incubated separately at 5℃, 25℃ and 45℃, respectively. Twenty nine s...

Cyanobacterial secondary metabolites have a diverse antagonistic activity that lead to disintegration of microbial growth. The study was conducted to evaluate the antifungal property possessed by cyanobacteriaAnabaena variabilis in retarding the growth of plant pathogenic fungal species. It was observed that the extracts prepared from Anabaena variabilis were capable of diminishing the growth a...

Epiphytic micro-organisms isolated from fruits and leaves surfaces of apples from different orchards were screened for antagonistic activity against Penicillium expansum. From all micro-organisms tested the new strain CPA-5 of Pseudomonas syringae, isolated from organic orchard, was selected. This strain was very effective against Botrytis cinerea, P. expansum and Rhizopus stolonifer at various...

Novel copper(II) complexes have been synthesized from the macrocyclic Schiff bases derived from Knoevenagel condensed β-ketoanilides (obtained by the condensation of acetoacetanilide and substituted benzaldehydes), 4-aminoantipyrine and o-phenylene diamine. The structural features have been determined from their analytical and spectral data. All the Cu(II) complexes exhibit square planar geomet...

A cell-free system which catalyzes the biosynthesis of terpene hydrocarbons when supplemented with mevalonate, Mn(2+), and ATP was prepared from the scutellum-embryonic axis region of maize seedlings. The capacity of this system for the production of terpene hydrocarbons was enhanced 50- to 100-fold when the seedlings were exposed for 48 hours to the fungus Rhizopus stolonifer prior to tissue h...

Cyclic voltammetric measurements were performed for Co(II), Ni(II), Cu(II) and Zn(II) complexes of 1: 1alternating copolymer, poly(3-nitrobenzylidene-1-naphthylamine-co-succinic anhydride) (L) and Ni(II) and Cu(II) complexes of 1: 1alternating copolymer, poly(3-nitrobenzylidene-1-naphthylamine-co-methacrylic acid) (L1). The in vitro biological screening effects of the investigated compounds wer...
