CONTRIBUTIONS BY THE COAUTHORS

Chapter 3
Dr. F. Gich has supervised the diploma-thesis from H. Hoffelner who has contributed
the alpine soil sample, the data for the ATP activity in soil slurries, the data of the
preliminary tests for detachment of soil bacteria from soil particles, and has produced
the MicroDrop cultures.

Chapter 4
Dr. F. Gich has supplied the unidentified acidobacterial enrichment culture of the alpine
soil sample. Dr. P. F. Dunfield has contributed the acidobacterial pure culture of strain
Wbg-1 of the forest soil sample and its complete 16S rRNA gene sequence.

Chapter 5
Dr. F. Gich has supervised the diploma-thesis from H. Hoffelner who has contributed
the alpine soil sample.

I hereby confirm the above statements.
