P. fluorescens is responsible for the highest depredation of milk because of its capacity to synthesize extracellular lipase and protease which hydrolyze milk fat and proteins. Several P. fluorescens synthesize an extracellular caseinolytic metalloprotease, called AprX. It is important to rapidly detect the presence of a contamination of raw milk by a(More)
Streptococcus thermophilus PB18 can grow between 20° and 52°C and is resistant to various stresses such as heat, acidic or cold shock. During cold shock, a protein of 21.5 kDa was previously shown to be induced in S. thermophilus. In addition to its cold-shock induction, 2D-PAGE revealed that the 21.5-kDa protein was also expressed during the stationary(More)
We report the serendipitous discovery of a human plasma phosphate binding protein (HPBP). This 38 kDa protein is co-purified with paraoxonase (PON1). The association between HPON1 and HPBP is modulated by phosphate and calcium concentrations. The HPBP X-ray structure solved at 1.9 A resolution is similar to the prokaryotic phosphate solute-binding proteins(More)
AIMS This study investigated the effect of growth conditions on proteolytic activity of a Pseudomonas strain, named Pseudomonas sp. LBSA1, isolated from bulk raw milk. It was compared with three Pseudomonas chlororaphis and one Pseudomonas fluorescens strain from culture collections. METHODS AND RESULTS Bacteriae were grown in a minimal salt medium. For(More)
