2. A new tool for faster construction of marine biotechnology collaborative networksAna Rotter, Susana P. Gaudêncio, Katja Klun, Jan-Niklas Macher, Olivier Thomas, Irem Deniz, Christine Edwards, Ernesta Grigalionyte-Bembič, Z. Ljubešić, Johan Robbens, Giovanna Cristina Varese, Marlen I. Vasquez, 2021, drugi znanstveni članki Povzetek: The increasing and rapid development in technologies, infrastructures, computational power, data availability and information flow has enabled rapid scientific advances. These entail transdisciplinary collaborations that maximize sharing of data and knowledge and, consequently, results, and possible technology transfer. However, in emerging scientific fields it is sometimes difficult to provide all necessary expertise within existing collaborative circles. This is especially true for marine biotechnology that directly addresses global societal challenges. This article describes the creation of a platform dedicated to facilitating the formation of short or mid-term collaborative networks in marine biotechnology. This online platform (https://www.ocean4biotech.eu/map/) enables experts (researchers and members of the marine biotechnology community in general) to have the possibility to showcase their expertise with the aim of being integrated into new collaborations/consortia on the one hand, or to use it as a search tool to complement the expertise in planned/running collaborations, on the other. The platform was created within the Ocean4Biotech (European transdisciplinary networking platform for marine biotechnology) Action, funded under the framework of the European Cooperation in Science and Technology (COST). To build the platform, an inquiry was developed to identify experts in marine biotechnology and its adjunct fields, to define their expertise, to highlight their infrastructures and facilities and to pinpoint the main bottlenecks in this field. The inquiry was open to all experts in the broad field of marine biotechnology, including non-members of the consortium. The inquiry (https://ee.kobotoolbox.org/single/UKVsBNtD) remains open for insertion of additional expertise and the resulting interactive map can be used as a display and search tool for establishing new collaborations.

3. Editorial : marine biotechnology, revealing an ocean of opportunitiesAna Rotter, Susana P. Gaudêncio, Arita Dubnika, Marlen I. Vasquez, 2022, drugi znanstveni članki Povzetek: The ocean, including its coastal areas and covering more than 70% of the Earth’s surface, has always represented an important environmental and economic resource. Indeed, almost 40% of the global population lives in coastal communities (United Nations, 2017). With its ecosystem services, the ocean represents a pivotal role in human society (Rayner et al., 2019). Undeniably, the ocean provides food, regulates the climate, provides oxygen and ensures economic resources through its shipping routes and tourism opportunities. Additionally, the ocean is home to organisms that have for centuries sparked the scientific interest of many research groups to uncover the biodiversity and functions of these fascinating marine ecosystems. Through their biological and chemical diversity, marine organisms synthesize unique secondary metabolites, biopolymers and enzymes produced in response to environmental stimuli. Secondary metabolites play important biological roles in improving competitiveness, providing chemical defence against predators or competitors and facilitating reproductive processes (Rotter et al.). Screening of these natural products and their producer organisms, coupled with the search of their unique biological activities that could be used in various industries, is tackled within marine (blue) biotechnology. Marine organisms and microorganisms can be investigated, and their primary and secondary metabolites, biopolymers and enzymes can be used as lead agents for nutraceutical and pharmaceutical industries to improve processes (e.g., in drug delivery) and as a source of bio-inspired materials for numerous biotechnological applications. Although this field has been appearing since the 1960s and 1970s, it is still considered an emerging field and marine biotechnology is still in its infancy (Rayner et al., 2019; Rotter et al.). This is because many marine environments are extreme ones that are either hardly accessible for sampling and harvesting and/or are home to organisms that cannot be cultured or grown in laboratory conditions. Consequently, a lot of advancement in the field of marine biotechnology was hampered until recent advances in science were achieved, including sampling methods, high-throughput methods and transdisciplinary collaborations.

4. Marine environmental plastic pollution : mitigation by microorganism degradation and recycling valorizationJuliana Oliveira, Afonso Belchior, Verônica D. Da Silva, Ana Rotter, Željko Petrovski, Pedro Lúcio Almeida, Nídia D. Lourenço, Susana P. Gaudêncio, 2020, pregledni znanstveni članek Povzetek: Plastics are very useful materials and present numerous advantages in the daily life of individuals and society. However, plastics are accumulating in the environment and due to their low biodegradability rate, this problem will persist for centuries. Until recently, oceans were treated as places to dispose of litter, thus the persistent substances are causing serious pollution issues. Plastic and microplastic waste has a negative environmental, social, and economic impact, e.g., causing injury/death to marine organisms and entering the food chain, which leads to health problems. The development of solutions and methods to mitigate marine (micro)plastic pollution is in high demand. There is a knowledge gap in this field, reason why research on this thematic is increasing. Recent studies reported the biodegradation of some types of polymers using different bacteria, biofilm forming bacteria, bacterial consortia, and fungi. Biodegradation is influenced by several factors, from the type of microorganism to the type of polymers, their physicochemical properties, and the environment conditions (e.g., temperature, pH, UV radiation). Currently, green environmentally friendly alternatives to plastic made from renewable feedstocks are starting to enter the market. This review covers the period from 1964 to April 2020 and comprehensively gathers investigation on marine plastic and microplastic pollution, negative consequences of plastic use, and bioplastic production. It lists the most useful methods for plastic degradation and recycling valorization, including degradation mediated by microorganisms (biodegradation) and the methods used to detect and analyze the biodegradation.

5. Valorization of marine waste : use of industrial by-products and beach wrack towards the production of high added-value productsVita Rudovica, Ana Rotter, Susana P. Gaudêncio, Lucie Novoveská, Füsun Akgül, Linn Kristin Akslen-Hoel, Diogo A. M. Alexandrino, Olga Anne, Lauris Arbidans, Miroslava Atanassova, Magdalena Bełdowska, Jacek Bełdowski, Amit Bhatnagar, Oskars Bikovens, Katja Klun, 2021, pregledni znanstveni članek Povzetek: Biomass is defined as organic matter from living organisms represented in all kingdoms. It is recognized to be an excellent source of proteins, polysaccharides and lipids and, as such, embodies a tailored feedstock for new products and processes to apply in green industries. The industrial processes focused on the valorization of terrestrial biomass are well established, but marine sources still represent an untapped resource. Oceans and seas occupy over 70% of the Earth’s surface and are used intensively in worldwide economies through the fishery industry, as logistical routes, for mining ores and exploitation of fossil fuels, among others. All these activities produce waste. The other source of unused biomass derives from the beach wrack or washed-ashore organic material, especially in highly eutrophicated marine ecosystems. The development of high-added-value products from these side streams has been given priority in recent years due to the detection of a broad range of biopolymers, multiple nutrients and functional compounds that could find applications for human consumption or use in livestock/pet food, pharmaceutical and other industries. This review comprises a broad thematic approach in marine waste valorization, addressing the main achievements in marine biotechnology for advancing the circular economy, ranging from bioremediation applications for pollution treatment to energy and valorization for biomedical applications. It also includes a broad overview of the valorization of side streams in three selected case study areas: Norway, Scotland, and the Baltic Sea.

6. From the sea to aquafeed : a perspective overviewOrhan Tufan Eroldogan, Brett Glencross, Lucie Novoveská, Susana P. Gaudêncio, Buki Rinkevich, Giovanna Cristina Varese, Maria F. Carvalho, Deniz Tasdemir, Ivo Safarik, Soren Laurentius Nielsen, Céline Rebours, Lada Lukić-Bilela, Johan Robbens, Evita Strode, Berat Z. Haznedaroglu, Marlen I. Vasquez, Ivana Čabarkapa, Slađana Rakita, Katja Klun, Ana Rotter, 2023, pregledni znanstveni članek Povzetek: Aquaculture has been one of the fastest-growing food production systems sectors for over three decades. With its growth, the demand for alternative, cheaper and high-quality feed ingredients is also increasing. Innovation investments on providing new functional feed alternatives have yielded several viable alternative raw materials. Considering all the current feed ingredients, their circular adaption in the aquafeed manufacturing industry is clearly of the utmost importance to achieve sustainable aquaculture in the near future. The use of terrestrial plant materials and animal by-products predominantly used in aquafeed ingredients puts a heavily reliance on terrestrial agroecosystems, which also has its own sustainability concerns. Therefore, the aquafeed industry needs to progress with functional and sustainable alternative raw materials for feed that must be more resilient and consistent, considering a circular perspective. In this review, we assess the current trends in using various marine organisms, ranging from microorganisms (including fungi, thraustochytrids, microalgae and bacteria) to macroalgae and macroinvertebrates as viable biological feed resources. This review focuses on the trend of circular use of resources and the development of new value chains. In this, we present a perspective of promoting novel circular economy value chains that promote the re-use of biological resources as valuable feed ingredients. Thus, we highlight some potentially important marine-derived resources that deserve further investigations for improving or addressing circular aquaculture.
