Asexual Reproduction: Spore Forming Bacteria

Sporulating bacteria Introduction Sporulation is asexual reproduction that occurs when environmental conditions surrounding Bactria become inappropriate for protection and protection. Spores are haploid and unicellular and are produced by meiosis in the sporangium of diploid sporozoites. Under convenient conditions, spores can utilize mitosis to promote new organisms that produce multicellular gametes that eventually continue to produce gametes.

Eukaryotic microorganisms can propagate sexually or asexually, but bacteria and archaebacteria can only propagate asexually. Bacteria and archaebacteria, in most cases, participate in a process called two divisions. In this process, one cell divides into two equally sized cells. Other less common processes include multiple nuclear fission, germination and spore production. This process starts with cell elongation and requires careful expansion of cell membranes and cell walls in addition to increasing cell volume. The cell begins to replicate its DNA and is ready to have two copies of the chromosome. The protein FtsZ is essential for membrane formation, which initially appears as a ring in the middle of elongated cells. After separating the nucleus into each end of the elongated cells, the formation of the membrane is complete and the elongated cells are divided into two equally sized daughter cells.

Asexual reproduction of Basidiomycete occurs by germination or asexual sporulation. Germination occurs when parental cell proliferation is divided into new cells. Any cell can germinate. Asexual sporulation occurs in conidiophores. The diaphragm of the distal cell divides the nucleus of the random number into cells. The cell wall becomes thickened into a protective layer, spores fall off and disperse (SparkNotes Editors, 2009). Rhizopus stolonifer is a common species belonging to this group. Medically relevant genus includes Mucor, Rhizomucor and Rhizopus (Deacon JW, 2005 and Kamistein D, 2002). Humans usually infect the upper respiratory tract by inhaling aerial spores, but may also be infected with primary gastrointestinal infections by ingesting contaminated food (Koneman et al., 2006).
