Growth by fission: Growth by budding: $+88 Mycelial growth: ●+Q8→ Spore Germ tube Hypha Hypha Apical growth Mycelium Main types of microbial growth.Fission is typical for bacterial growth and it results in two identical cells.Most yeast species divide by budding,which results in two non-identical cells,since the mother cell can be identified by a scar,as indicated in the figure.Mycelial growth is most common among moulds but it is also characteristic for Streptomyces.Branched hyphae form together a mycelium which may appear as a viscous diffuse mycelium or may aggregate into dense pellets which makes the broth less viscous.The hyphal growth is uni-directional,shown as elongation of the hyphal tips(apical growth)
