Bacteria usually reproduce asexually. In case of sexual reproduction, certain plasmids genetic material can be passed between bacteria. On the other hand, viruses mainly carry information-for example, DNA or RNA, packaged in a protein and/or membranous coat.Viruses harness the host cell's machinery to reproduce.acteria usually reproduce asexually.

The vegetative form of B. cereus grows in a range of 10 to 50Â°C, with a temperature optimum between 30 and 40Â°C. However, the individual cold-tolerating strains can also multiply at temperatures of 4 to 6Â°C; in these cases the generation times are, however, considerably longer.
Lactobacillus is killed if exposed to temperatures over. 55Â°C (130Â°F), and does not grow well below 37Â°C (98Â°F). We will incubate at 50Â°C, a. temperature on the high side of its preferred growth temperature (122Â°F), a temperature. which inhibits the growth of pathogenic bacteria. (Note that many recipes call for cooler. temperatures than this.
