Isolation and purification of propionicin PLG-1, a bacteriocin produced by a strain of Propionibacterium thoenii.

abstract：:It has long been assumed that prolonged holding of environmental samples at the ambient air temperature prior to bacteriological analysis is detrimental to isolation and detection of Vibrio cholerae, the causative agent of pandemic cholera. The present study was aimed at understanding the effect of transporting enviro...
