Effect of mixed substrade on the stability of anaerobic digestion

Değişik konsantrasyonlardaki (2 ve 4 $g.l^{-1}$) farklı karbonhidrat karışımlarının (nişasta-glikoz, nişasta-früktoz, nişasta-glikoz-früktoz) anaerobik arıtımın stabilitesine etkisi incelenmiştir. Sıralı bir substrat kullanımı gözlenmiştir; ilk olarak glikoz ve/veya frütoz tüketildikten sona nişasta kullanımı başlamıştır. Glikoz ve/veya früktoz nişasta kullanımını katabolit represyona uğratmıştır.

Karışık substratin anaerobik arıtım stabilitesine etkisi

In order to find out effects of mixed substrates on the stability of anaerobic digestion, mixtures of various carbohydrates (starch-glucose, starch-fructose and starch-glucose-fructose) at varying concentrations (2 $g.l^{-1}$ and 4 $g.l^{-1}$ ) were used. A sequential substrate utilization was observed, glucose and/or fructose depletion followed by starch utilization. Glucose and/or fructose exerted catabolite repression on starch utilization.
