[Tex/LaTex] Unwanted line-breaking of hyphenated word in bibliography

bibliographiescitinghyphenationline-breaking

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:

enter image description here

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

Best Answer

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.
