Fourteen pesticides (fungicides, herbicides, and insecticides) were tested to determine whether they had deleterious effects on the bioinsecticide Bacillus popilliae, the causal agent of milky disease. All of these pesticides reduced levels of spore viability, spore germination, and/or vegetative cell growth when they were tested over a range of concentrations from 0 to 1,000 ppm of active ingr...

Meloidogyne incognita egg masses were immersed in different concentrations of six volaule fatty acids to bioassay their toxic effect on embryonic development and hatching. Exposure to a 250 ppm aqueous solution of volatile fatty, acids completely suppressed egg hatching within 48 hours. When exposed to a 125 ppm concentration hatching was reduced 75 % by acetic acid, 91% by propionic acid, 23% ...

A combination of molecular modelling and experiments was conducted to study the separation acrylic acid propionic through extractive distillation with polar aprotic entrainers. It found that can be efficiently separated a entrainer, resulting in entrainment making most volatile compound. Vapour-liquid equilibrium were 25 wt% acid, propionic, 50% entrainer. Dimethyl sulfoxide (DMSO) induce highe...

Differing efficiencies of utilization of acetic, propionic and butyric acids in both fasting and fattening sheep have been demonstrated by Blaxter and his colleagues (Armstrong & Blaxter, 1957a, b ; Armstrong, Blaxter & Graham, 1957). In fasting sheep, when the acids were given singly as the sole source of energy, the heat increment with acetic acid (41 yo of the energy of the metabolized acid)...

Derrick MacFabe’s hypothesis that propionic acid generated by gut bacteria induces autism [1], while compelling, leaves one question largely unanswered: Why do children with inborn propionic acidemia rarely show autistic behavior? Although exacerbations of Propionic Acidemia (PA) bear “some resemblance” to autism spectrum disorders (ASD), MacFabe noted, only one case of autism associated with P...

Propionic acid (PA) is a fungicide and bactericide, registered to control fungi and bacteria in stored grains, hay, grain storage areas, poultry litter, and drinking water for livestock and poultry. European Union (EU) certifies PA as the great of grain preserver and most efficient in controlling Salmonella and other pathogens. Recently it is used as feed additive in poultry and non-ruminant pr...

Essential oils and organic acids are used as feed additives to improve health status and reduce colonization with pathogens. Although bactericidal in vitro, concentrations achieved in the animal gut are probably not lethal to pathogens. The aim of this study was to investigate the effects of cinnamaldehyde, carvacrol and cinnamic, lactic and propionic acids on the ability of Salmonella typhimur...
