Abstract

The bioconversion of soy stalk (SS) lignocellulose by three different starins of Pleurotus eryngii from various origins by solid state fermentation was studied during 40 days. The effect of rice bran ratio, 5% or 10% (w/w), on lignin degradation and laccase activity were measured througout the fermentations while, total crude protein and C/N ratio of the remaining substrate were determined at the end of the fermentations. The degradation of lignocellulose was found by the determination of acid soluble lignin (Klason lignin) content. All the strains degraded lignin with different extents. The amount of lignin degradation was decreased by the addition of the higher quantities of rice bran (SS+10% RB). The highest lignin degradation was obtained as 24.43% by P. eryngii var. ferulae (E) and the highest protein level was found to be %13.32 by P. eryngii (H). We determined that the laccase activity was generally decreased by the addition of the higher quantities of rice bran (10%). Maximum laccase activity (204.39 U/L) was obtained by P. eryngii (E) on SS + 5% RB at the end of the fermentation. This study showed that, after fungal treatment soy stalk can be used as a feed for ruminants with its higher feeding value.

Özet

Katı substrat fermentasyonu şartlarında, değişik kaynaklardan elde edilen Pleurotus eryngii'nin üç farklı suşu ile lignoselülozik soya sapının (SS) biyodönüşümü 40 gün süre ile incelenmiştir. Çalışmada, farklı oranlarda (%5 ve %10 w/w) pirinç kepeğinin (PK) fermentasyon esnasında lignin yıkımına ve lakkaz aktivitesine, fermentasyon sonunda ise kalan substratın ham protein ve C/N oranına etkisi belirlenmiştir. Lignoselülozun degredasyon oranı, asitle çözünür lignin (Klason lignin) içeriğinin belirlenmesiyle ortaya konmuştur. Ligninin tüm suşlar tarafından yıkıldığı ancak bu yıkımın farklı oranlarda gerçekleştiği saptanmıştır. Lignin yıkım oranının, yüksek miktarda pirinç kepeği eklenen ortamda (SS+%10 PK) azaldığı gözlenmiştir. En yüksek lignin yıkım oranının ise P. eryngii (E) tarafından %24,43 olarak gerçekleştiği tespit edilmiþtir. En yüksek ham protein seviyesi P. eryngii (H) ile %13,32 olarak bulunmuştur. Lakkaz aktivitesinin yüksek miktarda (% 10) PK eklenmesiyle azaldığı belirlenmiştir. Maksimum lakkaz aktivitesi (204,39 U/L) P. eryngii (E) ile %5 PK ortamında 40. günde ölçülmüştür. Böylece, soya saplarının fungal fermentasyondan sonra kazandıkları yüksek besleyici değerden dolayı ruminantlar için bir besin katkı maddesi olarak kullanılabileceği belirlenmiştir.
