Abstract
The mechanisms that bacteria have evolved for acetate resistance are probably similar to those that the bacteria have evolved for tolerance against other weak organic acids, such as lactic, propionic and citric acid. Since the mentioned acids are often the end- or by-products in many biotechnological processes, it is very important that the microorganisms involved in the process, tolerate their high concentrations. Studies of the genetic basis of the acetate-resistance are therefore not only a valuable step in direction of understanding the response of bacteria to acetate but also more generally, to inhibitory concentrations of metabolic by-products. The objectives of the proposed project are therefore: (i) to elucidate the molecular basis of acetate tolerance, (ii) to isolate and identify genes important for naturally acetate-resistant bacteria, (iii) to investigate the applications of these genes to increase acetate production by acetic acid bacteria and (iv) to confer higher acetate tolerance also to other industrially important bacteria.
