Pilot-plant production of protease by Alternaria tenuissima.
Agar slants of a selected Alternaria tenuissima strain were illuminated to give conidia suitable for further propagation. For production of protease with an optimal caseolytic activity in the region of pH 8 to 10, the fungus was cultivated in steel fermentors with 6- and 60-liter working capacity. Maximal activity, 1.5 enzyme units per liter, was attained in a medium based on liver after about ...
متن کاملTenuazonic acid production by Alternaria alternata and Alternaria tenuissima isolated from cotton.
Cultures of Alternaria alternata (three isolates) and Alternaria tenuissima (three isolates) obtained from cottonseeds and bolls were toxigenic when cultured on various laboratory media. A mycotoxin was isolated and identified as tenuazonic acid by using solvent partition, thin-layer chromatography, and instrument analyses. Toxicity was monitored with brine shrimp and chicken embryo bioassays. ...
متن کاملFirst Report of Leaf Spot Caused by Alternaria tenuissima on Black Chokeberry (Aronia melanocarpa) in Korea
In July 2015, diseased leaves of black chokeberry (Aronia melanocarpa) were observed in Danyang and Gochang, Korea. The symptoms appeared as circular or irregular brown leaf spots, from which Alternaria tenuissima was isolated. The isolates were cultured on potato dextrose agar, and their morphological characteristics were observed under a light microscope. The colonies were whitish to ash colo...
متن کاملAltertoxins with potent anti-HIV activity from Alternaria tenuissima QUE1Se, a fungal endophyte of Quercus emoryi.
Screening of a small library of natural product extracts derived from endophytic fungi of the Sonoran desert plants in a cell-based anti-HIV assay involving T-cells infected with the HIV-1 virus identified the EtOAc extract of a fermentation broth of Alternaria tenuissima QUE1Se inhabiting the stem tissue of Quercus emoryi as a promising candidate for further investigation. Bioactivity-guided f...
متن کاملMutation of Alternaria tenuissima FCBP-252 for hyper-active α-amylase
Production of extracellular α-amylase enzyme by a filamentous fungus, Alternaria tenuissima was studied in solid-state fermentation (SSF) as well as submerged fermentation (SmF). The potential strain was successfully mutated by UV and ethyl methanesulfonate (EMS). High-level of α-amylase activity was obtained by the mutant At-Ch-5.6 (76.75 Units mL) after chemical treatment followed by UV mutan...
