Effect of exogenous electron shuttles on growth and fermentative metabolism in Clostridium sp. BC1.

In this study, the influence exogenous electron shuttles on the growth and glucose fermentative metabolism of Clostridium sp. BC1 was investigated. Bicarbonate addition to mineral salts (MS) medium accelerated growth and glucose fermentation which shifted acidogenesis (acetic- and butyric-acids) towards solventogenesis (ethanol and butanol).

Rapid establishment of p-nitrophenol biodegradation in acetate-fed aerobic granular sludge.

The aim of the study was to investigate the acclimation of precultivated acetate-fed aerobic granular sludge to a toxic xenobiotic biodegradation. Establishment of p-nitrophenol (PNP) biodegradation in acetate-fed aerobic granular sludge and concomitant changes in the microstructure and bacterial community were determined. Rapid establishment of PNP utilization was observed in the granular sludge when fed with PNP as the sole carbon source.
