Conservation of ornamental stone by Myxococcus xanthus-induced carbonate biomineralization.
Increasing environmental pollution in urban areas has been endangering the survival of carbonate stones in monuments and statuary for many decades. Numerous conservation treatments have been applied for the protection and consolidation of these works of art. Most of them, however, either release dangerous gases during curing or show very little efficacy. Bacterially induced carbonate mineraliza...
متن کاملHeat-shock-induced proteins from Myxococcus xanthus.
Optimal conditions for two-dimensional gel electrophoresis of total cellular proteins from Myxococcus xanthus were established. Using these conditions, we analyzed protein patterns of heat-shocked M. xanthus cells. Eighteen major spots and 15 minor spots were found to be induced by heat shock. From N-terminal sequences of 15 major spots, DnaK, GroEL, GroES, alkyl hydroperoxide reductase, aldehy...
متن کاملBiomineralization induced by Myxobacteria
Myxococcus xanthus is a Gram negative, non-pathogenic, common soil bacterium that belongs to the δsubdivision of the Proteobacteria. According to the data, it is demonstrated that, depending on the chemistry of the culture media, M. xanthus is able to induce the formation of phosphates (struvite, schertelite, newberyite), carbonates (calcite, Mg-calcite, vaterite) and sulfates (barite, taylorit...
متن کاملLytic enzyme produced by Myxococcus xanthus.
Hart, Beth A. (Cornell University, Ithaca, N.Y.), and Stanley A. Zahler. Lytic enzyme produced by Myxococcus xanthus. J. Bacteriol. 92:1632-1637. 1966.-Strain FBa of Myxococcus xanthus releases into its culture medium an enzyme capable of lysing Micrococcus lysodeikticus cells and of releasing N-acetyl amino sugars from their cell walls. The lysin is stable at pH values near neutrality and at t...
متن کاملLipolytic enzymes in Myxococcus xanthus.
The genome of Myxococcus xanthus encodes lipolytic enzymes in three different families: patatin lipases, alpha/beta hydrolases, and GDSL lipases. One member of each family was characterized. The protein encoded by MXAN_3852 contains motifs characteristic of patatins. MXAN_5522 encodes a protein with the G-X-S-X-G motif characteristic of the lipase subfamily of alpha/beta hydrolases. MXAN_4569 e...
