Effect of Various Agro-Residues on Nutritive Value of Pleurotus eryngii (DC. ex Fr.) Quel. var. ferulae Lanzi

Abstract

In this study, the effect of various compost medium on the nutritive value of P. eryngii var. ferulae were determined. Dry matter, moisture, crude ash, protein, fat and organic matter were determined as 91. 7-92.7, 7.3-8.3, 5.4-6.1, 8.5-19.7, 2.5-4.1 and 85.8-86.9% of air-dried weight, respectively. There were no significant differences in crude ash and organic matter content for P. eryngii var. ferulae grown on various agro-residues. Crude protein and fat contents varied significantly, the lowest protein content was obtained in natural wild sample (8.5%), whereas the highest were obtained in WS + 10% RB (18.0%), WS-CS (1:1) + 10% RB (18.5%), WS + 20% RB (18.9%) and WS-CS (1:1) + 20% RB (19.7%). Minimum crude fat content was 2.5% in WS-CS (1:1), maximum was 3.9-4.1% in WS + 10% RB, WS + 20% RB, WS-CS (1:1) + 10% RB and WS-CS (1:1) + 20% RB. Mineral contents varied significantly, their contents were determined to be 14.3-22.6 for K, 0.12-0.70 for Ca and 0.1-0.3 for mg g -1 Na as macro elements, 519.5-1142.3 for Fe, 33.5-102.5 for Zn, 41.6-64.6 for Mn, 25.8-48.5 for Cu and 1.3-2.3 for mg kg -1 Cr as micro elements. Pb, Co, Ni and Cd concentrations were under the detection limit of the metod used. 84%3.9-4.1'dir. Element içeriklerinin değişken olduğu ve 14.3-22.6 K, 0.12-0.70 Ca ve 0.1-0.3 mg kg -1 Na gibi makro elementler, 519.5-1142.3 Fe, 33.5-102.5 Zn, 41.6-64.6 Mn, 25.8-48.5 Cu ve 1.3-2.3 mg kg -1 Cr gibi mikro elementler olarak belirlenmiştir. Ayrıca; Pb, Co, Ni ve Cd konsantrasyonları kullanılan metodun belirleme limitinin altında bulunmuştur.

Production and characterization of laccase from Pleurotus ferulae in submerged fermentation

“…P. ferulae is reported to contain nematicidal metabolites and to have nematicidal activity (Li et al 2007). Some studies of P. ferulae have focused on the production of basidiocarp using agricultural wastes as substrate (Akydz and Yildiz 2007;Kirbag and Akyuz 2008). Punelli et al (2009) reported detection of laccase activity in two Pleurotus spp.…”

Effect of Thymus vulgaris post‐extraction waste and spent coffee grounds on the quality of cultivated Pleurotus eryngii

“…In Europe, the most common substrate used for growing oyster mushrooms is wheat and rye straw, which are easily accessible and not troublesome to prepare. In countries with a warmer climate such as Japan, Korea, and China, P. eryngii is cultivated on sawdust of Japanese cedar, or ground corncobs supplemented with bran, and contained in polypropylene bottles (Akyüz & Kirbağ, 2010;Beetz & Kustudia, 2004;Yamanaka, 2011). The most commonly used substrates include oak, beech, poplar, alder, birch, wild cherry, mango, and elm sawdust (Kwon & Kim, 2004).…”

“…For yielding, air temperature was maintained at 15°C ± 1°C and relative humidity at 85%-90%. The cultivation was additionally Gąsecka et al (2015), Gençcelep, Uzun, Tunçtür, and Demirel (2009), Manzi, Gambelli, Marconi, Vivanti, and Pizzoferrato (1999), Rodriguez-Estrada and Royse (2007), Siwulski et al (2017) K 15 300-40 540 Akyüz and Kirbağ (2010), Gençcelep et al (2009), Guo, Lin, and Lin (2007), Manzi et al (1999), Rodriguez-Estrada and Royse (2007) Mg 1 000-2 000 Gençcelep et al (2009), Guo et al (2007) 2010…”
