Stimulation of aryl metabolite production in the basidiomycete Bjerkandera sp. strain BOS55 with biosynthetic precursors and lignin degradation products

Article Abstract:

The effects of photosynthetic precursors or aromatic acids on the synthesis of aryl metabolites by Bjerkandera sp. strain BOS55 were analyzed in the presence and absence of Mn. The synthesis of veratryl alcohol and veratraldehyde was stimulated by addition of lignin degradation products such as veratrate, p-anisate and 3-chloro-p-anisate in the presence of Mn. However, Mn inhibited the formation of aryl metabolites such as p-anisaldehyde and 3-chloro-p-anisaldehyde by the white rot fungi.

Growth of the fungus Cladosporium sphaerospermum with toluene as the sole carbon and energy source

Article Abstract:

The fungus Cladosporium sphaerospermum may be able to grow by breaking down gaseous toluene. This fungus was isolated from a filter that removed toluene from contaminated air. Analysis of the fungus suggested that it operated by first removing the methyl group from the toluene. As the first known fungus to use toluene as a source of energy and carbon, C. spaerospenmum may play an important role in the development of biofilters that can operate at various water concentrations and pHs.

Fungal metabolism of toluene: monitoring of fluorinated analogs by (super 19)F nuclear magnetic resonance spectroscopy

Article Abstract:

Many fungi can metabolize toluene and oxidation begins at the aromatic ring or the methyl group. However, conversion of fluorotoluenes begins at the side chain and results in fluorinated benzoates, which are further metabolized to catecholic intermediates.
