Spatial and temporal variation of Escherichia coli in water and soil with relation to water parameters at the estuary of Karnafuly River, Bangladesh

  This study examined the concentrations of Escherichia coli in soil and water samples, and some physicochemical properties of water collected from the Karnafuly River estuary, Bangladesh during March-June 2012. Among the water parameters, temperature was in the range 26.5  to 32°C, salinity varied between 0 and 5 ppt, pH values ranged from 7.5 to 7.9 and dissolved oxygen (DO) was...

Effects of Mn2+ levels on the resistance properties of Bacillus cereus spores

  In some Bacillus species, manganese levels influence the resistance properties of spores. To determine if this was true for Bacillus cereus, bacteria were sporulated with different MnCl2 concentrations resulting in spores with 30-fold differences in core Mn2+ levels. Spores with different Mn2+ levels displayed no differences in resistance to dry heat, UV...
