The influence of the petroleum ferrofluids upon the cellulosolytic fungi Chaetomium globosum Kunze : Fr

We present a study on the development of the cellulosolytic fungi Chaetomiu m globosum Kunze:Fr, under the influence of a petroleum ferrofluid, added a t various concentrations to the culture medium. A positive influence of the ferrofluid was revealed at the level of the growth rate during the first w eek of the experiment. Further! the biomass accumulation rate was diminishe d in the sample in comparison to the control without the addition of ferrof luid. The ubiquitous capacity of the fungi for iron internalization under t he form of complex combinations known as siderophores, is probably related to the observed behavior of Chaetomium globosum Kunze:Fr.
