An extranuclear oligomycin-resistant mutant of Aspergillus nidulans was isolated and biochemically analyzed and it was concluded that this small lipophilic protein is coded by a mitochondrial gene determining oligomecin resistance, is synthesized on mitochondrial ribosomes and is associated with the membrane sector of the ATPase complex.

Using a double-labelling technique in the absence and presence of cycloheximide, followed by immunoprecipitation of the enzyme complex with antiserum against Neuospora crassa F1 ATPase, it has been shown that this subunit is synthesized on cytoplasmic ribosomes.

A new iron-containing peptide which inhibits the growth of Gram-positive and some Gram-negative bacteria was isolated from the broth of Streptomyces AS-K-753, which is similar in many properties to the sideromycin but differs from it in certain crucial characteristics.

The two antibiotics ASN-136 and monoketo-organomycin showed very close similarities in their UV, IR spectra and elemental analysis to those of tuberactinomycin and yazumycin respectively, which revealed the novelty of the two former antibiotics.

A relationship between the length, L, of the zone occupied by a compound, the weight, C, of compound applied and the distance, D, travelled by the developing solvent, has been found to hold under specified conditions and can be used to determine organic compounds alone or in admixture.
