Molecular characterization of transesterification activity of novel lipase family I.1.

Lipase's thermostability and organic solvent tolerance are two crucial properties that enable it to function as a biocatalyst. The present study examined the characteristics of two recombinant thermostable lipases (Lk2, Lk3) based on transesterification activity. Conversion of C12-C18 methyl ester with paranitrophenol was investigated in various organic solvent.

Simple enrichment and independent cultures to expand bacterial community analysis from Gedongsongo hot spring.

Denaturing gradient gel electrophoresis was used to identify bacterial communities from Gedongsongo hot spring, Indonesia, by culture-independent and -dependent procedures. Predominant species were found to be closely related to beta-proteobacteria, particularly from genus Ralstonia and Delftia. Other species present include alpha- and gamma-proteobacteria and Thermus groups.
