Article Synopsis
- The study explores the "One Strain Many Compounds" (OSMAC) approach to discover bioactive compounds by introducing stress factors, focusing on how grazing pressure impacts the metabolome of marine diatoms when co-cultured with zooplankton.
- In large-scale bioreactor experiments, the researchers found that diatom extracts exhibited higher bioactivity in assays against human lung cells when under grazing stress from zooplankton, although it did not significantly impact biofilm formation or bacterial growth.
- The analysis of metabolic profiles revealed distinct differences between the diatom's chemical outputs in monoculture versus co-culture, suggesting that grazing stress alters diatom biochemistry and could enhance the OSM
Androgenesis is a form of uniparental reproduction leading to progenies inheriting only the paternal set of chromosomes. It has been achieved with variable success in a number of freshwater species and can be attained by artificial fertilization of genetically inactivated eggs following exposure to gamma (γ), X-ray or UV irradiation (haploid androgenesis) and by restoration of diploidy by suppression of mitosis using a pressure or thermal shock. The conditions for the genetic inactivation of the maternal genome in the European sea bass (Dicentrarchus labrax L.
