Abstract. Pseudomonas fluorescens was found to grow in a mineral medium supplemented with up to 50 mM aluminum, complexed to citrate, the sole source of carbon.

At stationary phase while virtually no diminution in cellular yield was observed in the presence of mM aluminum, only 31% of bacterial yield was recorded in media with 50 mM :// Aims.

To identify the molecular networks in P seudomonas fluorescens that convey resistance to toxic concentrations of Z n, a common pollutant and hazard to biological systems. Methods and Results. Pseudomonas fluorescens strain ATCC was cultured in growth medium with millimolar concentrations of Z n.

Enzymatic activities and metabolite levels were monitored with the aid of in‐gel   The involvement of phosphatidyl­ethanolamine (PE) in the simultaneous detoxification of aluminium, iron, zinc, gallium, and calcium has also been shown (Appanna et al.

Metals and their derivatives can interact with fungi in various ways depending on the metal species, organism, and environment, while fungal metabolic activities can also influence speciation and mobility.
