Abstract
Methane is one of the main sources of air-pollution and more than 63% of atmospheric methane (346 Tg Y-1) is derived from anthropogenic activities with landfills and agriculture being the main pollution sources. Rhodotorula glutinis is a unicellular, oleaginous, saprophytic yeast with a high lipid (>60%) and high carotenoid contents. The ability of R. glutinis to utilise methane as a sole carbon source was reported by Wolf et al. (1979, 1980), therefore could be a favorable option for sustainable management of green house gas emission from animal production; However, our results show that R. glutinis is not a methane-oxidising yeast and refutes earlier reports therefore it is not a suitable option for methane remediation.
