Bacterial Cooperative Organization Under Antibiotic Stress (2007)
Physica A, Eshel Ben-jacob, Inon Cohen, Ido Golding, David L. Gutnick, ...
Bacteria have developed sophisticated modes of cooperative behavior to cope with unfavorable environmental conditions. Here we report the e#ect of antibiotic stress on the colonial development of...
Nakar, David, Gutnick, David L.
The genes associated with the biosynthesis of the polymeric bioemulsifier emulsan, produced by the oil-degrading Acinetobacter lwoffii RAG-1 are clustered within a 27-kbp region termed the wee...
Effect of Emulsan on Biodegradation of Crude Oil by Pure and Mixed Bacterial Cultures
Foght, Julia M., Gutnick, David L., Westlake, Donald W. S.
Crude oil was treated with purified emulsan, the heteropolysaccharide bioemulsifier produced by Acinetobacter calcoaceticus RAG-1. A mixed bacterial population as well as nine different pure cultures...
A Role for Exopolysaccharides in the Protection of Microorganisms from Desiccation
Ophir, Tslil, Gutnick, David L.
Mucoid strains of Escherichia coli, Acinetobacter calcoaceticus, and Erwinia stewartii were significantly more resistant to desiccation than corresponding isogenic nonmucoid mutants (survival rates...
Use of Neomycin in the Isolation of Mutants Blocked in Energy Conservation in Escherichia coli
Kanner, Baruch I., Gutnick, David L.
A neomycin-resistant mutant of Escherichia coli K-12 unable to grow on Krebs cycle intermediates has been isolated. The mutant retained its respiratory capacity, but lacked membrane...
Purification and Properties of Mg2+-Ca2+ Adenosinetriphosphatase from Escherichia coli
Nelson, Nathan, Kanner, Baruch I., Gutnick, David L.
A procedure for the purification of Mg2+-Ca2+ adenosinetriphosphatase (EC 3.6.1.3) from E. coli, yielding relatively large amounts of highly active enzyme, is described. The enzyme consists of four...
