A bacterial strain TI-B10 was isolated from forest soil in Taiwan. The strain showed 46 U/ml of anti-tyrosinase activity. On the basis of the typical colony appearance and 16S rRNA gene sequences analysis, the strain TI-B10 belonged to the genus Streptomyces. The antityrosinase activity of the strain could be improved to 73 U/ml under optimal cultural conditions at pH 8.0 and 30°C in the YMG medium.

Dormancy is a profound and ancient adaptation found in a wide spectrum of plants and animals of all habitats. In diapause the switch between active and dormant states is driven by hormonal mechanism that usually includes a photoperiodic pace-maker. Temperature, food limitation and some other stress factors as well are shown as driven by diapause induction in aquatic invertebrates. In the last decade, diapause studies from a wide variety of topics have demonstrated that diapause switch mechanisms may be developed to create novel applications in biotechnology. Resting eggs accumulated in the surface lake sediments represent a “bank” of zooplankton species …
