Destruction of toxic fungi with low concentrations of methyl bromide.

Aspergillus parasiticus and Penicillium rubrum spores at the level of 10(4) to 10(5) / g were completely killed by prolonged exposure to 30 to 45 mg of methyl bromide per liter.

Methyl Bromide Soil Fumigation Alters Plant Element Concentrations

Soil fumigation is used to eliminate plant pathogens and weeds in commercial practice and to eliminate organisms in controlled experiments, e.g., vesicular arbuscular mycorrhizal fungi (VAMF). This study was conducted to study the effect of methyl bromide fumigation on plant accumulation of 14 elements and assess plant colonization by VAMF after fumigation. Field experiments were conducted near...

Modulation of petite induction by low concentrations of ethidium bromide.

When starved, exponential phase cells of Saccharomyces cerevisiae are exposed to lo-25 UM ethidium bromide in buffer, the proportion of respiration deficient mutants in the population exhibits a rapid increase, followed by a pronounced decrease. This "self-rescue" by the mutagen can be dissociated from and studied independently of its mutagenic action and is shown to exhibit different requireme...

Interaction of methyl bromide with soil.

Because methyl bromide (CH3Br) is a widely used agricultural fumigant for soil disinfection, it is important to know the chemical behavior and fate of CH3Br as a result of its use for soil treatment. A solid-state 13C NMR study of 13CH3Br-treated soil and soil-component samples shows that methylation of soil organic matter may be the major pathway for degradation of CH3Br in soils. Adsorption o...

Treatment of methyl bromide poisoning with haemodialysis.

Acute accidental methyl bromide poisoning was treated with haemodialysis. The treatment was successful in removing bromide from the blood but the patient persists with severe neuropsychiatric sequelae. To the best of our knowledge haemodialysis has not been used previously for the treatment of organic bromide poisoning.
