Streptomycetes can grow through small filter capillaries.
Streptomycetes are Gram-positive bacteria growing as branching filaments. The filaments are able to deform. This ability allows the cells to squeeze through capillaries as small as 0.2 micron in diameter. After passage through the capillaries, numerous hyphae are morphologically altered to a helical structure.
