Secondments Przemysław Dąbek, Ewa Górecka, Marta KrzywdaUS to MPT


The objective of the secondments was primarily to increase the volume of Haslea ostrearia strains and adapt the cultures to Microphyt infrastructure. This task consisted of determination of culture kinetics in small scale batch and semi-continuous set of cultures in order to establish an appropriate culture systems for optimized culture strategy, that will provide the inoculum for the industrial scale production. Laboratory-scale culture strategies were tested for optimal ecophysiological conditions, including alterations of culture medium, system and physical and chemical conditions.

Secondary objective was laboratory-scale production of marennine-rich extracts. To achieve that the simplified protocol for the quantification of marennine obtained from scaled-up cultures was implemented. Moreover, simplified production of rich marennine extracts and yield characterization was determined in a laboratory scale.
