Degradation of organophosphonates by Penicillium citrinum

Abstract

Utilization of organophosphonates as the sole source of phosphorus, carbon or nitrogen by a soil isolate of Penicillium citrinum was studied. Penicillium citrinum was found to utilize 2‐aminoethylphosphonic and 2‐oxoalkylphosphonic acids as the sole phosphorus source whereas 1‐hydroxyalkylphosphonates as well as 1‐aminoalkylphosphonates and their dipeptides did not support the growth of the fungus. The mould did not metabolize any of the phosphonates tested, when they served as the sole carbon or nitrogen source. Penicillium citrinum is perhaps the first mould strain isolated from soil, shown to be capable of organophosphonate degradation.

Isolation and Characterization of two New Microbial Strains Capable of Degradation of the Naturally Occurring Organophosphonate––Ciliatine

“…Studies concerning metabolism of phosphonates in eukariotic microbial cells are documented by only several reports on the utilization of phosphonates as sole phosphorus source by fungal isolates (Bujacz et al 1995;Krzyśko-Łup-icka et al 1997;Sobera et al 1997;Zboiń ska et al 1992). The ability of fungal isolates to utilize organophosphonates as sole source of nitrogen are limited to two examples.…”

Degradation of glyphosate and other pesticides by ligninolytic enzymes

“…Many bacteria transform the herbicide in the absence of a P source (Singh and Walker 2006 and references therein). Some fungi can also use glyphosate as the only P source, e.g., Penicillium citrinum (Zboinska et al 1992), P. notatum (Bujacz et al 1995), Trichoderma harzianum, Scopulariopsis sp. and Aspergillus niger (Krzyśko-Lupicka et al 1997) and as the only N source, e.g., P. chrysogenum (Klimek et al 2001).…”

Isolation and identification of a phosphate-solubilizing bacterium Pantoea stewartii subsp. stewartii g6, and effects of temperature, salinity, and pH on its growth under indoor culture conditions

“…Among the forms, DIP is the most important one, which can be absorbed by phytoplankton directly and therefore contributes to the pond productivity more effectively (Wu and Zhou 2005). ISIP and OP usually cannot be utilized by phytoplankton directly, but can be transformed to soluble forms under physical, chemical, or biological process (Kim et al 2003;Zboinska et al 1992).…”
