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.
of Bacteria. Since bacteria grow in many environments from artic oceans to hot springs, it is not surprising that the optimum growth temperatures vary. Bacteria from the human gut grow well at body temperature (37 C) but bacteria from plants may be killed at that temperature.ere are some suggested temperatures. 1  several days at 4 C. 2  2 days at 4 C; then 1 or 2 days at r.t. 3  two days at room temperture. 4  one or two days at 37 C. 5  24 hours at 55 C protect against drying and use twice the amount of agar to counter drying. 6  24 hours at 55 C; then 2 days at room temperature.
