Algal Heme Oxygenase from Cyanidium caldarium

Enzymatic heme oxygenase activity has been partially purified from extracts of the unicellular red alga Cyanidium caldarium, and the macromolecular components have been separated into three protein fractions, referred to as Fractions I, 11, and 111, by serial column chromatography through DEAE-cellulose and Reactive Blue 2-Sepharose. Fraction I is retained by DEAE-cellulose at low salt concentr...

Studies with Cyanidium Caldarium

The fine structure of Cyanidium caldarium, as seen in thin sections of KMnO(4)-fixed cells examined with the electron microscope, is described. This organism, whose taxonomic position among algae is undetermined, contains a single well defined chloroplast, a nucleus, and mitochondria. Studies, with the electron microscope, of Chlorella pyrenoidosa and Nostoc are also reported. Structural differ...

Sterols and Chloroplast Structure of Cyanidium caldarium.

A brief survey on the occurrence of algal sterols shows that green algae (Chlorophyta) are characterized by the presence of sitosterol (12) and a complex mixture of sterols as occurs in higher plants. However, among few exceptions to that, Chlorella, a "typical" green unicellular alga, possesses ergosterol as the major constituent (13). Recent investigations of Alcaide et al. (1) with marine re...

easySP: Nueva Aplicación para la Enseñanza de Procesado de Señal

— The present article presents a software application, developed by the authors, in the digital signal processing field, with educative purposes. This tool offers a graphic interface to perform signal processing presentations via plugins. The program allows users to add plugins designed in both XML format and Java.
