(Thomas Patrick Daniel), 1948- Suppression of microbial uptake or organic solutes by algal siderophores in a hardwater lake [electronic resource] / by T.P. Murphy, K.J. Hall and I. Yesaki. Burlington, Ont. : Aquatic Ecology Division, National Water Research Institute, [1986]. 18, [6] p. : ill. NWRI contribution series ; #86-137 Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references. "The bacterial degradation of organic compounds was suppressed in Black Lake, British Colmrbia, by the algal excretion of siderophores. Siderophores are specific chelators of iron that are produced when the supply of iron limits microbial growth. The siderophore isolated from Scenedesmus suppressed the bacterial assimilation of acetate by 81 to 97% and of glucose by 92 to 98%.Siderophore isolates Anabaena flos-aquae or an Anabaena isolated from Black Lake reduced the bacterial uptake of acetate by 14 to 92%. These results are inportant to any lake restoration procedure that alters the availability of iron and thus changes the production of siderophores (aeration, ferric chloride addition etc.)"--Management perspective.
