# Unwanted line-breaking of hyphenated word in bibliography

In .bib file:

@article{Kurahashi_Yokota2004,
author = "Kurahashi, M. and Yokota, A.",
title = "Agarivorans albus gen. nov., sp. nov., a $\gamma$-proteobacterium isolated from marine animals",
journal = "International Journal of Systematic and Evolutionary Microbiology",
volume = "54",
year = "2004",
pages = "693--697"
}


Output:

See that the \gamma proteobacterium word is broken up. I want to keep the gamma together on the same line as proteobacterium.

Try to write it as \hbox{$\gamma$-proteobacterium}, but I'm not sure if this is good for a citation. AFAIK there is some non-hyphenating dash, but I can't recall its name. –  Martin Scharrer May 25 '11 at 17:36
Non-hyphenating dash, huh? I'd be interested to know, if anyone knows what it's called. –  ptrcao May 26 '11 at 0:37
@Martin @ptrcao It's called \nobreakdashes and is to be followed by the requested sequence of one to three -. –  egreg May 26 '11 at 6:36

You can write

title = "Agarivorans albus gen. nov., sp. nov., a
$\gamma$\nobreakdashes-proteo\-bacterium isolated
from marine animals",


I've added a discretionary hyphen as the long word will probably create a badly underfull box, but hyphenating after "proteo" might be more acceptable.
