Authors:  HORIA L. BANCIU.
  Abstract:  Sulfur is one of the main elements whose natural cycling is essential to life on Earth. Chemical and biological processes are involved in the transformation of sulfur to different organic or inorganic compounds. Microorganisms take advantages of utilizing various sulfur compounds, either the reduced (serving as energy source) or the oxidized S-forms (electron acceptor). The sulfur cycle is also present in the extreme environments like saline and alkaline lakes. Purple sulfur bacteria and chemolithoautotrophic sulfur-oxidizing bacteria (SOB) are among the major groups that use reduced sulfur compounds as energy source and electron donor in the saline-alkaline lakes. The haloalkaliphilic SOB isolated from soda lakes proved to be highly specialized for the doubly extreme conditions of high salt concentration and high pH. Based on these properties, the haloalkaliphilic SOB from soda lakes can be usefully exploited in bioreactors with stable soda alkalinity and supplied with inorganic sulfur compounds for sulfur removal from waste streams..
