| culture age, temperature, and ph affect the polyol and trehalose contents of fungal propagules. | the growth and conidial physiology of the entomopathogenic fungi beauveria bassiana, metarhizium anisopliae, and paecilomyces farinosus were studied under different conditions. the effects of culture age (up to 120 days), temperature (5 to 35(deg)c), and ph (2.9 to 11.1) were determined. growth was optimal at ph 5 to 8 for each isolate and between 20 and 35(deg)c, depending on the isolate. the predominant polyol in conidia was mannitol, with up to 39, 134, and 61 mg g of conidia(sup-1) for b. ba ... | 1996 | 16535354 |
| comparison of biomass dry weights and radial growth rates of fungal colonies on media solidified with different gelling compounds. | penicillium commune, aureobasidium pullulans, and paecilomyces farinosus were grown on two different media solidified with agar, pluronic f-127, carrageenan x-4910, or carrageenan x-4910 overlaid with cellophane. growth on carrageenan x-4910 was generally the same as that on agar, as was the visual appearance of the colonies, e.g., the pigmentation. the carrageenan x-4910 gels had a melting point, depending on the medium, of 41 to 46(deg)c, and the dry weights of the colonies were readily determ ... | 1995 | 16535179 |
