<jats:title>Abstract</jats:title> <jats:p> The producing strain Streptomyces sp. 1010 was isolated from a shallow sea sediment from the region of Livingston Island, Antarctica. From the culture broth of this strain naturally active secondary metabolites were isolated identical to phthalic acid diethylester (C<jats:sub>12</jats:sub>H<jats:sub>14</jats:sub>0<jats:sub>4</jats:sub>, MW.222); 1, 3-bis (3-phenoxyphenoxy)benzene (C<jats:sub>30</jats:sub>H<jats:sub>22</jats:sub>O<jats:sub>4</jats:sub> , MW.446); hexaned ioic acidd ioctylester (C<jats:sub>22</jats:sub>H<jats:sub>42</jats:sub>O<jats:sub>4</jats:sub> , MW.370) and the new substance 2-amino-9, 13 -dimethylheptad ecanoic acid (C<jats:sub>19</jats:sub>H<jats:sub>39</jats:sub>NO<jats:sub>2</jats:sub> , MW.313). These compounds represent diverse classes of chemical structures and provideevidence for the untapped biosynthetic potential of marine bacteria from Antarctica.
