Oil spill has led to severe environmental and ecological problems. Due to the harsh environmental conditions, the bioremediation technology is not successfully used to remedy the oil spill in marine environment. In this study, immobilization technology was used to immobilize bacteria on natural organic carriers (i.e., wood chips and maize straw). The higher surface area of in wood chips leads to larger biomass density (0.0242 gVSS/g) than that of maize straw of 0.0097 gVSS/g carrier. Compared with biodegradation efficiency of free bacteria (44.79%), the immobilized bacteria on wood chips and maize straw reached to 73.39% and 52.28%, respectively. The high biological activity of the immobilized bacteria can be also explained by nutrients, such as TN (total nitrogen) and TP (total phosphorus), released from wood chips and maize straw, which was 8.83 mg/g and 5.53 mg/g, 0.0624 mg/g and 0.0099 mg/g, respectively.

Crude oil is a major pollutant of marine and coastal ecosystems, and it causes environmental problems more seriously. It is believed ultimate and complete degradation is accomplished mainly by microorganisms. In this study, we aim to search out for bacterial strains with high ability in degrading crude oil. From sediments contaminated by the petroleum spilled in 2007, an accident in Taean, South Korea, we isolated thirty‐one bacterial strains in total with potential application in crude oil contamination remediation. In terms of removal percentage after 7 days, one of the strains, Co17, showed the highest removal efficiency with 84.2% of crude oil in Bushnell‐Haas media. The Co17 strain even exhibited outstanding ability removing crude oil at a high salt concentration. Through the whole genome sequencing annotation results, many genes related with n ‐alkane degradation in the genome of Gordonia sp. Co17, revealed alkane‐1‐monooxygenase, alcohol dehydrogenase, and Baeyer–Villiger monooxygenase. Specially, for confirmation of gene‐level, alk B gene encoding alkane hydroxylase (alkane‐1‐monooxygenase) was found in the strain Co17. The expression of alk B upregulated 125‐fold after 18 hr accompany with the removal of n ‐alkanes of 48.9%. We therefore propose the strain Gordonia iterans Co17, isolated from crude oil‐contaminated marine sediment, could be used to offer a new strategy for bioremediation with high efficiency.

During the production and transportation of petroleum hydrocarbons, unsuitable operation and leakage may result in contamination of water and soil with petroleum hydrocarbons. Petroleum contamination causes significant marine environmental impacts and presents substantial hazards to human health. Bioremediation of contaminated water and soil is currently the effective and least harmful method of removing petroleum hydrocarbons from the environment. To improve the survival and retention of the bioremediation agents in the contaminated sites, microbial cells must be immobilized. It was demonstrated that immobilized microbial cells present advantages for degrading petroleum hydrocarbon pollutants compared to free suspended cells. In this study, the ability of a Bacillus strain (designed as Bacillus sp. VTVK15) to immobilize on PUF and to degrade crude oil was investigated. The immobilized Bacilllus strain had the highest number (5.38 ± 0.12 Í 108 CFU/g PUF) and a maximum attachment efficiency of 92% on PUF after 8 days. Analysis by GC-MS revealed that both free and immobilized cells of Bacillus sp. VTVK15 were able to degrade 65 and 90% of the hydrocarbons in 2% (v/v) crude oil tested after 14 days, respectively. The results suggest the potential of using PUF-immobilized Bacillus sp. VTVK15 to bioremediate petroleum hydrocarbons in an open marine environment.
