Abstract

Using a novel pine needle agar, fifteen bacterial species were isolated from pine litter. These bacteria were able to degrade aromatic hydrocarbons derived from lignin and utilize the ortho-cleavage of the $beta$-ketoadipate pathway to degrade protocatechuate or catechol. A different utilization array of aromatic hydrocarbons by these bacteria was also determined. This study provides the information on bacterial species living in pine litter and suggests that these bacteria have metabolic abilities to utilize aromatic hydrocarbons derived from lignin biodegradation.

Keywords: Bioremediation, biodegradation, biogeochemical cycling, lignin, aromatic hydrocarbons, $beta$-ketoadipate pathway
