Abstract

Background: As global awareness regarding climate change and environmental pollution outcomes arise, eco-friendly and negative emission technologies emerge.

Methods: In this scenario, polyhydroxyalkanoate (PHA)-accumulating microorganisms play an important role in the transition from the petrochemical-based non-biodegradable polymer to renewable, eco-friendly, and biocompatible materials. More specifically, CO₂ can be converted to biopolymers through photosynthesis by cyanobacteria and algae, posing as a promising technology for renewable material, CO₂, and petroleum-dependence mitigations. However, although many microorganisms can accumulate PHA intracellularly, limitations persist, such as the elevated cost and limited market availability.

Results: Herein is presented a patent-based mapping on technological trends of PHAs production, including its production by microalgae and cyanobacteria using the Questel Orbit Intelligence software (version 1.9.8) in complement with the Espacenet Patent Search database.

Conclusion: The inquiry on PHAs retrieved 34,243 patents filed since 1912, whereas 156 are related to their specific production by photosynthetic microorganisms, evidencing a prospective market for intellectual property.

藻类和蓝藻生产聚羟基烷酸酯的专利景观。

背景:随着全球对气候变化和环境污染后果的认识提高，环保和负排放技术应运而生。方法:在这种情况下，聚羟基烷酸酯(PHA)积累微生物在从石化基不可生物降解聚合物到可再生、环保和生物相容性材料的转变中发挥了重要作用。更具体地说，二氧化碳可以通过蓝藻和藻类的光合作用转化为生物聚合物，这是一项有前途的可再生材料、二氧化碳和石油依赖缓解技术。然而，尽管许多微生物可以在细胞内积累PHA，但局限性仍然存在，例如成本升高和市场供应有限。结果:本文利用Questel Orbit Intelligence软件(版本1.9.8)和Espacenet专利检索数据库，对pha生产的技术趋势进行了基于专利的映射，包括微藻和蓝藻的生产。结论:自1912年以来，对pha的调查检索到34,243项专利，其中156项与光合微生物的特定生产有关，证明了知识产权的潜在市场。
