Nutritional studies with Acetobacter suboxydans indicated that
when isoleucine, lysine, methionine, serine and arginine were singly
omitted from a complete amino acid mixture, no growth was obtained.
However, the organism could grow on single amino acids like glutamic
acid, histidine and proline. No growth was obtained with ammonium
sulfate as...
Rat liver microsomes are shown to contain an enzyme system
which converts the cyclodiene insecticides, aldrin, heptachlor and
isodrin to their corresponding epoxides, dieldrin, heptachlor epoxide,
and endrin. The microsomal fraction of 450 milligrams of liver from
male rats epoxidates 80 percent of a 20 to 50 microgram aldrin substrate...
An aspect of the metabolism of monoalkylhydrazines has been
investigated using both intact rats and rat liver microsomal enzyme
preparations.
Intact rats respired propane and n-butane on administration of 0.3-0.5 mmoles of isopropyl- and n-butylhydrazine, respectively.
Based upon dose administered, a five to ten percent
yield of hydrocarbon was obtained....
