“…As far as we know, this is the first report on the mineralization of PAHs by a fungus of the generous Nematoloma spp., and mineralization values of phenanthrene and pyrene are comparable to those published for other white-rot fungi (BUMPUS 1989, MORGAN et al 1991, SACK et al 1995. The mineralization was additionally investigated in solid (straw) cultures.…”

The white-rot fungus Nematoloma frowardii was examined for the ability to degrade [ring U-i4C]-phenanthrene and [4,5,9,10-i4C]pyrene in liquid and solid (straw) cultures in a period of 63 days. 3.2% phenanthrene and 8.6% pyrene were mineralized to 14C0, in liquid cultures, respectively. A considerable higher mineralization of 1 1.2% (phenanthrene) and 46.5% (pyrene) was detected in straw cultures. Metabolites were identified by their UV absorption spectra. N. frowardii transformed phenanthrene to phenanthrene 9,lO-dihydrodiol. Pyrene 4,5-dihydrodiol was identified as major metabolite in pyrene degradation.Polycyclic aromatic hydrocarbons (PAHs), like phenanthrene (three ring PAH) and pyrene (four ring PAH) are widely distributed pollutants in terrestrial and aquatic ecosystems (BLUMER 1976). The ability of wood-decaying fungi to mineralize PAHs seems to be connected with the activity of ligninolytic enzymes, since mineralization in liquid or soil cultures has mostly been described for wood-decaying fungi like the white-rot fungi Phanerochaete chrysosporium (SANGLARD et al. 1986, BUMPUS et al. 1985, BUMPUS 1989, MORGAN et al. 1991, Trametes versicolor (SACK et al. 1995), and Kuehneromyces mutabilis (SACK and FRITSCHE 1997).A screening of wood-decaying fungi for producing radical generating extracellular enzymes has selected the South American white-rot fungus Nematoloma frowardii with a high manganese peroxidase (MnP) activity (HOFRICHTER and FRITSCHE 1997). We used phenanthrene and pyrene as model PAHs for investigations on the mineralization of these substances in liquid and solid (straw) substrates by N. frowardii. Materials and methods

“…Though oyster mushroom is the third important mushroom of culinary value, there has been a upsurge in Pleurotus mushroom research activities in the last two decades not only for its nutritional and medicinal values but also many other biopotentialities of Pleurotus species such recycling of comprehensive account of nutritional with some medicinal agricultural residues [12,14], bioconversion of lignoaspects of Pleurotus species [15,16], production or improved animal feed [17], bioremediation and biodegradation of xenobiotics [18,19], degradation of industrial dye [20,21], bioremediation [12,22], degradation of xenobiotics [23,24], bioconversion of lignocellulosic wastes [25], enzyme production [26,27], etc. Medicinal attributes of Pleurotus species are given below.…”

“…Another ribonuclease, pleuturegin, was also isolated from both fresh and dried sclerotia of P. tuber-regium [17]. Later, in [19] the fruiting bodies of oyster mushroom, they observed a novel-like protein having HIV-1 reverse transcriptase reported inhibitory activity [18]. Similarly, hot water extracts of P. sajor-caju and P. pulmonarius inhibit HIV-1 reverse transcriptase activity by SU2 molecule having 4.5 kDa mol.…”

Oyster mushroom is consumed all over the world due to its taste, flavor, high nutritional value, and some medicinal properties. Many species of this genus are rich in proteins with essential amino acids, polysaccharides, essential amino acids, dietary fibers, important minerals, and some vitamins. Because of this nutritional composition and presence of bioactive molecules, oyster mushroom has been reported to have anticancer, antihypertensive, antihypercholestromic, antidiabetic, antiobesity, antiaging, antimicrobial, and antioxidant activities. The high nutritional value and potent medicinal uses suggest that Pleurotus mushrooms are important functional foods or nutraceuticals.

“…Fungal transformation of PAHs is an area of increasing interest (Anastasi et al 2008;Morgan et al 1991;Sutherland 1988). Yeasts, particularly those common in marine environments, have the potential to oxidize PAHs (Cerniglia and Crow 1981;Pinto et al 1979;MacGillivray and Shiaris 1993).…”

To investigate the effects of physiological properties on polycyclic aromatic compound (PAH) degradation, the surface tension and emulsification activities, and cell surface hydrophobicity of five PAH-degrading yeast isolates were compared to Saccharomyces cerevisiae from cultures grown with glucose, hexadecane, or naphthalene as carbon sources. The cell surface hydrophobicity values for the five yeast strains were significantly higher than for S. cerevisiae for all culture conditions, although these were highest with hexadecane and naphthalene. Strains with higher hydrophobicity showed higher rates of naphthalene and phenanthrene degradation, indicating that increased cell hydrophobicity might be an important strategy in PAH degradation for the five strains. Emulsification activities increased for all five yeast strains with naphthalene culturing, although no relationship existed between emulsification activity and PAH degradation rate. Surface tensions were not markedly reduced with naphthalene culturing.
