Abstract
Azospirillum brasilense sp7 was exposed to 2 mM Zn2+ in minimal medium upon which the cells turned black and non-motile within 24 h. A strep tomycin-resistant variant did not exhibit this phenomenon and is sensi tized to zinc. A prelude to encystation was the elution of a melanin-l ike pigment into the medium.
