The distribution of the genus
Saccharopolyspora in soil samples collected from the southwest islands in Okinawa Prefecture, Japan, was studied. The habitation of the genus
Saccharopolyspora greatly depended on soil characteristics; especially soil type and pH value, but not on organic matter content nor moisture content. The percentages of the positive soil samples for the genus
Saccharopolyspora collected from sugar-cane fields, beaches (alkaline pH) and coconut yards were 83, 75 and 67 %, respectively. The largest concentrations of the genus
Saccharopolyspora were found in the surface horizon (0 to 5 cm in depth), whereas no
Saccharopolyspora was isolated from the horizon below 20 cm.
