Distribution functions of variables characterizing the mycelial morphology of Streptomyces hygroscopicus grown in glucose-limited chemostat cultures.

The distribution of variables characterizing the morphology of the mycelium of Streptomyces hygroscopicus grown in glucose-limited chemostat cultures at different specific growth rates were investigated statistically. The values of the hyphal growth unit (L/N) and the values of the distance from the apex to the first branch (Lp) are normally distributed, but the values of the distance between neighbouring branches are logarithmically normal distributed. The distribution functions are discussed from the biological point of view.
