Evaluation of assimilatory sulphur metabolism in Caldicellulosiruptor saccharolyticus

Pawar, Sudhanshu LU and van Niel, Ed LU (2014) In Bioresource Technology 169. p.677-685
Abstract
Caldicellulosiruptor saccharolyticus has gained reputation as being among the best microorganisms to produce

H2 due to possession of various appropriate features. The quest to develop an inexpensive cultivation

medium led to determine a possible replacement of the expensive component cysteine, i.e. sulphate.

C. saccharolyticus assimilated sulphate successfully in absence of a reducing agent without releasing

hydrogen sulphide. A complete set of genes coding for enzymes required for sulphate assimilation were

found in the majority of Caldicellulosiruptor species including C. saccharolyticus. C. saccharolyticus displayed

indifferent physiological behaviour to source of sulphur when grown... (More)
Caldicellulosiruptor saccharolyticus has gained reputation as being among the best microorganisms to produce

H2 due to possession of various appropriate features. The quest to develop an inexpensive cultivation

medium led to determine a possible replacement of the expensive component cysteine, i.e. sulphate.

C. saccharolyticus assimilated sulphate successfully in absence of a reducing agent without releasing

hydrogen sulphide. A complete set of genes coding for enzymes required for sulphate assimilation were

found in the majority of Caldicellulosiruptor species including C. saccharolyticus. C. saccharolyticus displayed

indifferent physiological behaviour to source of sulphur when grown under favourable conditions

in continuous cultures. Increasing the usual concentration of sulphur in the feed medium increased substrate

conversion. Choice of sulphur source did not affect the tolerance of C. saccharolyticus to high partial

pressures of H2. Thus, sulphate can be a principle sulphur source in an economically viable and more sustainable

biohydrogen process using C. saccharolyticus. (Less)
