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.
For determination of optimum pH, it was selected in range of 3 to 10. thermodenitrificans type strain DSM 465T grows well at 50 to 65[degrees]C, with optimum pH values of 6 to 8 and in the presence of 3% NaCl. Isolation and characterization of novel denitrifying bacterium Geobacillus sp.
