This study investigates the nutritional value of white button mushroom Agaricus bisporus X25 which cultivated on six composts viz., wheat straw compost, reed (Phragmites australis) straw compost and the mixture (1:1) (wheat straw and reed straw) which decomposed with or without adding bacterial inoculum Streptomyces during substrates composting. In general, using bacterial inoculum raised values of proteins and ortho-dihydric phenol in fruiting bodies of A. bisporus X25, while the mixture compost raised protein content and reed compost raised ortho-dihydric phenol of fruiting bodies of A. bisporus. Thus, this mushroom strain has considered amounts of proteins and phenols.Keywords: Compost, nutritional value, pharmaceutical value, Phragmites australis, Streptomyces.

“…Moreover, Kalme et al (2009) suggested that, presence of amino group represents the starching of pyrrol ring like structure at a peak of 1340 cmG 1 through FTIR, indicated that the some of the metabolites produced after decolourization. Therefore, the development of processes based on laccase seems to be an attractive biocatalyst due to their potential in degrading synthetic dyes of diverse chemical structure, currently employed in the industry (Hou et al, 2004;Couto and Sanroman, 2005).…”

Laccases (benzenediol oxygen oxidoreductases, EC 1.10.3.2) are polyphenol oxidases (PPO) that catalyze the oxidation of various substituted phenolic compounds by using molecular oxygen as the electron acceptor. In the present study, Bacillus subtilis MTCC 2414 were employed for the production of laccase using guaiacol as a substrate under Submerged Fermentation (SmF) condition. Laccase was partially purified by salt precipitation method followed by dialysis. The synthetic dyes such as Orange 3R, Yellow GR and T-Blue were used for degradation studies using culture filtrate, free and immobilized laccases. The immobilized laccase obtained by entrapment method using sodium alginate was optimized and it exhibited maximum activity at pH 7 (321 U mLG 1 ) and temperature 35°C (317 U mLG 1 ). Similarly, free laccase was also optimized and the maximum activity was observed at pH 9 (309 U mLG 1 ) and temperature 35°C (339 U mLG 1 ). Surprisingly, Yellow GR dye was found to be highly degraded up to 81.72% by immobilized laccase when compared to free laccase (74.69% of T-Blue) and culture filtrate (72.16% of Orange 3R) respectively. The FTIR spectrum showed a spectrum peaks at 2110.12 c/m in control dye and degraded Yellow GR exposed peak at 3406.36 cmG 1 which represents C-N stretching of aromatic amine group in dyes. Therefore, high degradation ability of laccase from B. subtilis MTCC 2414 makes them attractive catalyst for biotechnological applications.

“…Other factors also play a role. Static cultures of P. ostreatus and Trametes gallica were reported to be superior to agitated cultures (Hou et al 2004, whilst in Irpex lacteus no differences were seen (Kasinath et al 2003, Shin 2004, and in Funilia troggi an agitated culture outperformed a static one (Birhanli & Yesilada 2006). Also culture volumes have an influence.…”

“…Nitrogen supplementation in SSF of selected agro-and forestrywastes (saw dust, oil palm frond, wheat straw, beech tree leaves) can very much raise enzyme yields of various white-rot fungi (D´Souza et al 1999, Vikineswary et al 2006. Other studies report N-limitation to be better for laccase production in P. ostreatus (Hou et al 2004) and Pycnoporus cinnabarinus . On a superficial view, results may appear to be contradictory .…”

“…Several inducers have been applied to increase yields of laccase: copper, phenols, 2,5-xylidine and related compounds in T. versicolor (Collins & Dobson 1997, Tavares et al 2005, Kollmann et al 2005, Domínguez et al 2007, Ryan et al 2007), ethanol in P. cinnabarinus (Lomascolo et al 2003, Meza et al 2006, aromatic compounds including veratryl alcohol in Botryosphoraeria sp. (Vasconcelos et al 2000, Dekker & Barbosa 2001, copper and phenolic compounds in Panus tigrinus (Chernykh et al 2005), copper, cotton stalk extract, dimethyl sulphoxide, and the synthetic substrate ABTS [2,2'-azino-di-(3-ethylbenzothialozin-6-sulphonic acid)] in P. ostreatus (Ardon et al 1996, Hou et al 2004, Shah et al 2006, and copper and lignin-related compounds in Pleurotus pulmonarius . Complex substrates such as sugar cane bagasse and lignocellulosic material such as wood and peanut shells have also been shown to be effective in various fungi (D 'Souza et al 1999, Arora & Gill 2001, Linke et al 2005, Makela et al 2006.…”
