1. ESTERÓIS COMO MARCADORES MOLECULARES DA CONTAMINAÇÃO FECAL NO SISTEMA ESTUARINO IGUAÇU-SARAPUÍ, NOROESTE DA BAÍA DE GUANABARA (RJ) / STEROLS AS MOLECULAR MARKERS OF FECAL POLLUTION IN IGUAÇU-SARAPUÍ ESTUARINE SYSTEM, GUANABARA BAY NORTHEAST (RJ)
The contamination by domestic sewage of the Iguaçu River and Sarapuí channel, located in the north-western sector of Guanabara Bay, was investigated by the determination of sterols and elemental composition (C and N) of organic matter in suspended matter and superficial sediments. Physico-chemical and chemical characterization of water and sediments were c

2. Sterol Requirements of T-Strain Mycoplasmas
T-strain mycoplasmas are very sensitive to digitonin, amphotericin B, and progesterone. This sensitivity and the relatively high content of cholesterol found in the cells indicated a possible requirement of T-strain mycoplasmas for sterols. This suspected requirement was demonstrated directly in a lipid-poor medium and can be met by cholesterol, as well as b
