Ten fungal isolates with an ability to degrade crude oil were isolated from select marine substrates, such as mangrove sediments, Arabian Sea sediments, and tarballs. Out of the ten isolates, six belonged to , two to and one each to and as identified using ITS rDNA sequencing. The selected ten fungal isolates were found to degrade the long-chain -alkanes as opposed to short-chain -alkanes from the crude oil. Mangrove fungus #NIOSN-M126 () was found to be highly efficient in biodegradation of crude oil, reducing the total crude oil content by 77% and the individual -alkane fraction by an average of 95.37%, indicating it to be a potential candidate for the development into a bioremediation agent.
从选定的海洋底物(如红树林沉积物、阿拉伯海沉积物和焦油球)中分离出了十种具有降解原油能力的真菌菌株。在这十种分离菌株中,通过ITS rDNA测序鉴定,六种属于 ,两种属于 , 和 各一种。研究发现,所选的十种真菌菌株能够降解原油中的长链 -烷烃,而不是短链 -烷烃。红树林真菌#NIOSN-M126( )在原油生物降解方面表现出高效性,将原油总含量降低了77%,单个 -烷烃组分平均降低了95.37%,表明它是开发成生物修复剂的潜在候选菌株。
