L. lactis, S. pyogenes and E. faecalis were grown in C-limited chemostat cultures at various pH's and dilution rates. General flux distribution, yields and other physiological factors were studied.

Martijn Bekker (1979) was born in Amstelveen (The Netherlands). He started his studies in biology in 1997 at the University of Amsterdam, and graduated in 2003 with specializations in molecular microbiology and in immunology. The internships during his undergraduate studies were carried out in the labs of Prof. dr. B. Oudega (VU, Amsterdam, The Netherlands) and Prof. dr. F. Heffron (OHSU, Portland, Oregon, USA).
He continued with his graduate studies in 2003 in the Laboratory for Molecular Microbial
Challenge: Comparative analyses, as demonstrated by comparative genomics and bioinformatics, are extremely powerful for (i) transfer of information from (experimentally) well-studied organisms to the other organisms, and (ii) when coupled to functional and phenotypic information, insight in the relative importance of components to the observed differences and simalities. The central principle of this proposal is that important aspects of the functional differences between organisms derive not

Lactic acid bacteria generally use homolactic fermentation for generation of ATP. Here we studied the role of the lactate dehydrogenase enzyme on the general physiology of the three lactic acid bacteria Lactococcus lactis, Enterococcus faecalis and Streptococcus pyogenes. Surprisingly deletion of the ldh genes hardly affected the growth rate in chemically defined medium, however growth rate was affected in rich medium. Furthermore, deletion of ldh affected the ability for utilization of various
