Identification of Low-Molecular-Weight Nucleic Acid-Related Substances Secreted by Streptomyces aureofaciens.

Streptomyces aureofaciens growth in chemically defined medium is actively associated with the secretion of low-molecular-weight nucleic acid-related substances and is linked to low availability of phosphate. Thirteen pure compounds were isolated, of which seven were identified.

Abiotic reduction of 1,3-dinitrobenzene by aqueous dissolved extracellular polymeric substances produced by microorganisms.

Extracellular polymeric substances (EPS) secreted by microorganisms make up an important constituent of labile and semilabile dissolved organic matter in surface water. There are no literature reports on the capability of EPS to reduce organic pollutants. This study demonstrated that EPS could effectively reduce a probe nitroaromatic compound, 1,3-dinitrobenzene. In aqueous dissolved EPS (60.3 ...

Atypical Acid-fast Microorganisms: I. Nucleic Acid Fraction.

This paper deals with a preliminary study of the nucleic acid fraction of ten representative strains of atypical acid-fast bacilli isolated from sputum and gastric contents of patients with proven or suspected tuberculosis (Loesch and Petrik, 1939). Strains Ya and Fe were isolated from cultures which also contained colonies of virulent human-type tubercle bacilli. Cultures from which the remain...
