Abstract
Four chemoattractants and three media were used to isolate actinomycetes from environmental samples. Each chemoattractant was evaluated for its ability to attract motile-spored actinoplanetes. The attractants compared were γ-collidine,d-xylose, vanillin and phosphate-buffered potassium chloride (bKCl). The method of Hayakawaet al for preparing the chemoattractants was combined with a modified chemotactic method. Of the chemoattractants tested, γ-collidine yielded a slightly greater number of motile-spored actinoplanetes than bKCl ord-xylose, and a significantly greater number than vanillin. bKCl attracted about the same number of organisms asd-xylose. By using several attractants and media with a variety of soils, distinctly different isolates were obtained with each combination.
