Production of Saltants of Chaetomium globosum by Monochromatic Ultra-Violet Irradiation
ثبت نشده
چکیده
Experiments have been made on the production of mutations by irradiation with monochromatic ultra violet light. The basic object of the experiments was to see whether thresholds exist in this phenomenon of the type familiar in photo-chemical reactions. If such thresholds can be demonstrated, a technique of analysis of biological material might be opened up similar to that used by the physicist in his investigation of atomic nuclei, atoms, and molecules.

Saltant Production by Wave Lengths of Visible and Long Ultraviolet Monochromatic Irradiation, and a Comparison with Saltants Produced by Short Wave Lengths of Monochromatic Ultraviolet Irradiation in the Fungus Chaetomium Globosum
1. Saltants have been produced in the fungus Chaetomium globosum by longer wave lengths than previously reported-by 365 mmicro and by a visible line 404 mmicro. 2. Absence at these wave lengths of the K saltant, which is so abundant at short wave lengths, is marked. 3. Ratio of percentage irradiated spores germinating to control spores germinating decreases from 83 per cent at 265 mmicro, a sho...
متن کاملMutants Produced by X-irradiation of Spores of Chaetomium Globosum and a Comparison with Those Produced by Ultraviolet Irradiation
1. Mutants produced by x-irradiation of fungal spores of Chaetomium globosum have been compared with those produced by ultraviolet irradiation. 2. The most striking difference between the mutants produced by x-irradiation and ultraviolet irradiation is the absence in x-ray experiments of the K mutant which is produced in large numbers at short ultraviolet wave lengths. 3. A comparison is made o...
متن کاملGrowth and Mycotoxin Production by Chaetomium globosum Is Favored in a Neutral pH
Chaetomium globosum is frequently isolated in water-damaged buildings and produces two mycotoxins called chaetoglobosins A and C when cultured on building material. In this study, the influence of ambient pH on the growth of C. globosum was examined on an artificial medium. This fungus was capable of growth on potato dextrose agar ranging in pH from 4.3 to 9.4 with optimal growth and chaetoglob...
متن کاملA Study of Oxygen Absorption and Catalase Production During Growth of Chaetomium Globosum on Cotton Fiber and Yarn.
Damage to cotton by micro-organisms causes a serious loss to the cotton farmer, manufacturer, and consumer. For this reason studies are in progress in the Department of Agriculture on the growth and effect of various micro-organisms which cause deterioration of cotton. In an earlier investigation in this laboratory by Rogers, Wheeler, and Humfeld (1940) the growth of Chaetomium globosum Kunze o...

Phytophthora diseases have become a major impediment in the citrus production in Thailand. In this study, an isolate of Phytophthora denominated as PHY02 was proven to be causal pathogen of root rot of Pomelo (Citrus maxima) in Thailand. The isolate PHY02 was morphologically characterized and identified as Phytophthora palmivora based on molecular analysis of an internal transcribed spacer rDNA...
