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.
Resterilize the bacteriological loop and use it in the same manner as above to transfer mature slime mold fruiting bodies and spores to the same well or small region of the petri dish where the bacteria have been placed. Label the dish with your name and date, and place the dish in a protected area of the lab. The optimum temperature range for growth of the slime mold is 22-24oC (room temperature) and optimum relative humidity is 70-75%. The spores will germinate, releasing myxamoebae that will increase by mitosis and feed on the E. coli.
