Melanin's presence in marine microorganisms and its ability to enhance the growth of melanized fungi in extreme environments, such as soils contaminated with radionuclides, highlights its adaptive and protective role (Dadachova et al., 2007). Additionally, the production of melanin by marine actinomycetes and marine bacteria, including Vibrio natriegens, demonstrates its prevalence and importance in marine ecosystems (Vasanthabharathi & Jayalakshmi, 2020; Wang et al., 2020). Furthermore, the presence of melanin in aquatic organisms like whales indicates its role in photoprotection and adaptation to high UV radiation environments in the ocean (Häder et al., 2014).
The diverse sources of melanin in the marine environment underscore its potential for biotechnological and medical applications. Understanding the properties and functions of marine-derived melanin can lead to the development of novel materials with biomedical and biotechnological applications (Wang et al., 2020). Moreover, the review on melanin from marine actinomycetes emphasizes the biotechnological potential and importance of melanin from marine sources (Vasanthabharathi & Jayalakshmi, 2020).
The evidence from various studies supports the presence of melanin in the ocean, particularly in marine microorganisms, aquatic organisms, and marine bacteria. This underscores the ecological significance and potential applications of marine-derived melanin in biotechnology and medicine.
