Genetic characterization of a cell envelope-associated proteinase from Lactobacillus helveticus CNRZ32.
A cell envelope-associated proteinase gene (prtH) was identified in Lactobacillus helveticus CNRZ32. The prtH gene encodes a protein of 1,849 amino acids and with a predicted molecular mass of 204 kDa. The deduced amino acid sequence of the prtH product has significant identity (45%) to that of the lactococcal PrtP proteinases. Southern blot analysis indicates that prtH is not broadly distribut...
متن کاملVacuum Drying Characteristics of Some Vegetables
In this research the drying of four kinds of vegetables was investigated in a vacuum dryer. The effect of temperature on drying rate of samples at various temperatures (30, 35 and 45 °C) was studied. Six thin-layer drying models were fitted to drying data and suitable model was selected from them. Then effective moisture diffusivity and ...

2 Department of Food Science, University of Wisconsi nMad ison, WI 53706, USA A prolinase (pepR) gene was cloned from an industrial Lactobacillus helveticus strain (53/7). Three clones, hybridizing with a gene probe specific for a peptidase shown to have activity against diand tripeptides, were detected from a L. helveticus genomic library constructed in Escherichia coli. None of the three clon...

متن کاملNanosurgery: observation of peptidoglycan strands in Lactobacillus helveticus cell walls.
The internal cell wall structure of the bacterium Lactobacillus helveticus has been observed in situ in aqueous solution using an atomic force microscope (AFM). The AFM tip was used not only for imaging but presumably to remove mechanically large patches of the outer cell wall after appropriate chemical treatment, which typically leaves the bacteria alive. The surface exposed after this "surger...
