Strains of Actinomycetales (286 in toto) belonging to thirteen genera other than Streptomyces were isolated from different ecosystems in the Algerian Sahara. Among these strains, 32 showed antibiotic activity against at least one of the test organisms comprising four bacteria, two yeasts and several filamentous fungi, and twelve were antagonistic against both bacteria and fungi. The characteristic UV spectra of active extracts revealed that six strains produced non-polyenic antifungal substances and four synthetized polyenic substances. One strain of Spirillospora produced a pentaene antifungal substance. The only antibiotic so far known to be produced by this genus is spirillomycin.
从阿尔及利亚撒哈拉沙漠的不同生态系统中分离出了属于链霉菌属以外13个属的放线菌目菌株（共286株）。在这些菌株中，32株对至少一种受试生物具有抗菌活性，受试生物包括四种细菌、两种酵母和几种丝状真菌，其中12株对细菌和真菌均具有拮抗作用。活性提取物的特征紫外光谱显示，6株产生非多烯类抗真菌物质，4株合成多烯类物质。一株螺旋孢菌产生一种戊烯类抗真菌物质。该属目前已知产生的唯一抗生素是螺旋霉素。
