However, during the meeting of the Judicial Commission held during the Xth International (IUMS) Congress of Bacteriology and Applied Microbiology , H.G. Trüper proposed that the recommendations governing the use of the connecting vowel should be overruled by the usage in chemistry and physics. Consequently, in combined names, which include terms used in chemistry or physics the connecting vowel shall not be dropped when the following component starts with a vowel and when this may cause ambiguity or uncertainty in meaning . The Judicial Commission unanimously agreed to this proposal  and the spelling Thioalkalimicrobium sibiricum, must be used.Publication:
