In today's world one of the major environmental problems is the contamination of aquatic or terrestrial ecosystem due to spillage of hydrocarbon compounds produced due to various activities related to the petrochemical industry. In recent years, bioremediation has emerged as a promising technology for the restoration of these contaminated sites in an ecofriendly way.
The aim of present review literature is the compilation of patent documents on bioremediation of petroleum hydrocarbon pollutants to know technological advancements in this field.
This analysis was based on various criteria i.e. patenting trend over time, country-wise and assignee-wise comparisons and types of technology used in various patents. Some publicly available patent databases were used to retrieve the patent information from the year 2000 to 2016.
Patent applications were retrieved and it was observed that different types of technological approaches were used in developing the patents. United States accounted for maximum patent publications, followed by China, Korea, Japan, Russia, Great Britain, Mexico, India and Canada in developing bioremediation technologies. US based organization DU PONT is the leading group as patent assignee followed by Biosaint Co. Ltd in Korea.
Patenting activity in the field of bioremediation of petroleum hydrocarbon was not much commendable in the early 20th century. However, an increased trend was observed in the past few years. Further contribution in this aspect would help in stabilizing various global environmental as well as economic issues.
在当今世界，主要环境问题之一是由于石化行业各种活动产生的碳氢化合物泄漏导致水生或陆地生态系统受到污染。近年来，生物修复已成为一种以生态友好方式修复这些受污染场地的有前景的技术。
本综述文献的目的是汇编有关石油烃污染物生物修复的专利文件，以了解该领域的技术进展。
该分析基于各种标准，即随时间的专利趋势、按国家和受让人的比较以及各种专利中使用的技术类型。使用一些公开可用的专利数据库检索2000年至2016年的专利信息。
检索到专利申请，并观察到在开发专利中使用了不同类型的技术方法。在开发生物修复技术方面，美国的专利出版物最多，其次是中国、韩国、日本、俄罗斯、英国、墨西哥、印度和加拿大。美国的杜邦公司是作为专利受让人的领先集团，其次是韩国的Biosaint有限公司。
在20世纪初，石油烃生物修复领域的专利活动并不十分值得称赞。然而，在过去几年中观察到了增长趋势。在这方面的进一步贡献将有助于稳定各种全球环境以及经济问题。
