The strengths and weaknesses of Gordonia: a review of an emerging genus with increasing biotechnological potential.

This review about the genus Gordonia provides a current overview of recent research on a young genus that was introduced in the year 1997 ( Stackebrandt et al., 1997 ). This emerging genus has attracted increasing environmental, industrial, biotechnological and medical interest during the last few years, in particular due to the capabilities of its members to degrade, transform, and synthesize organic compounds as well as to the pathogenic effects that have been described in many case studies. The number of publications about Gordonia has increased significantly after the year 2004 (the year of the first Gordonia review published by Arenskötter et al.) describing 13 new validly published species (type strains), many newly described physiological and metabolic capabilities, new patent applications and many new case reports of bacterial infections. Members of the genus Gordonia are widely distributed in nature and it is therefore important to unravel the species richness and metabolic potential of gordoniae in future studies to demonstrate their environmental impact especially on the degradation of persistent organic compounds and their ecological participation in the carbon cycle of organic material in soil and water. This review summarizes mainly the current state of importance and potential of the members of this genus for the environmental and biotechnological industry ("the strengthsâ) and briefly its pathogenic impact to humans ("the weaknessesâ).
