Osmotic Stress in Gram Positive Bacteria
The laboratory objective is to study the adaptive changes that bacteria
undergoes when exposed to an osmotic stress. Aspects of the physiology and
metabolism, and genetic circuits of the stress response has been determined,
and their relation with the structural changes in
the envelope that are essential for the growth in extreme environments. These
results are relevant not only as basic knowledge but also in application.
Stress responses are directly related to stationary phase. The
micro-organisms used Bacillus subtilis, B. sphaericus,
B. thuringiensis, Lactobacillus casei are
employed in several biotechnological processes where better knowledge of
genetic, metabolic and structural modification would result in the
improvement of specific industrial processes. Lines of work Physiological and genetic modifications of the proteolytic system by osmotic stress
in Lb. casei Structure and composition of the cell envelop during osmotic
stress in B. subtilis and Lb. casei Heavy metals uptake using Gram positive bacteria and associated
polymers Production of crystal toxin under stress conditions in B. thuringiensis and B. sphaericus
