Alkaliphiles are a diverse group of relatively less known microorganisms living in alkaline environments. To thrive in alkaline environments, alkaliphiles require special adaptations. This adaptation may have evolved metabolites which can be useful f

Separation of cells in density gradients with temporary solidification of the gradient: Application to Escherichia coli forms obtained by microwave treatment of pure cultures

Autor: Saara Korpela, Mikhail Vainshtein, Timo Korpela, Tatiana Abashina

Publikováno v: Journal of microbiological methods. 153

Gelatin added in certain concentration into the density gradient mixtures allows to solidify and melt the gradient reversibly. Such a method was applied to separation of partially disintegrated Escherichia coli VKM B-125 cells in discontinuous sucros

Climate change and global economic pressures are strong drivers for energy economies to transition towards climate-neutrality, low-carbon economy and better energy and resource efficiencies. The response to these pressures, namely the increased use o
