Abstract: | Dye decolourizing peroxidase (DyP) is an emerging biocatalyst with enormous bioremediation and biotechnological potentials. This study examined the global trend of research related to DyP through a bibliometric analysis. The search term ‘dye decolourizing peroxidase’ or ‘DyP-type peroxidase’ was used to retrieve published articles between 2007 and 2019 from the Web of Science (WoS) and Scopus databases. A total of 62 articles were published within the period, with an annual growth rate of 17·6%. The highest research output was observed in 2015, which accounted for about 13% of the total output in 12 years. Germany published the highest number of articles (n = 10, 16·1%) with a total citation of 478. However, the lowest number of published articles among the top 10 countries was observed in India and Korea (n = 2, 3·2%). Research collaboration was low (collaboration index = 4·08). In addition to dye decolourizing peroxidase(s) and DyP-type peroxidase(s) (n = 33, 53·23%), the top authors keywords and research focus included lignin and lignin degradation (n = 10, 16·1 %). More so, peroxidase (n = 59, 95·2%), amino acid sequence (n = 27, 46·8%), lignin (n = 24, 38·7%) and metabolism (n = 23, 37·1%) were highly represented in keywords-plus. The most common conceptual framework from this study include characterization, lignin degradation and environmental proteomics. Apart from the inherent efficient dye-decolourizing properties, this study showed that DyP has emerging biotechnological potentials in lignin degradation and remediation of phenolic environmental pollutants, which at the moment are under explored globally. |
