Reuters innovation news article on using algal sunscreens as an alternative to synthetic sunblock, sometimes blamed for adverse effects on human skin. Featuring Dr Carole Llewellyn and Dr Alla Silkina.
Funding available for an EUROPEAN Ph.D. student in collaboration with Milford Haven Port Authority
TITLE: Evaluating the scientific and technical capacities towards sustainable production of sea vegetables in Milford Haven Port
The overarching goal of the proposed research is to balance aquaculture production and conservation needs within the Port. The student will investigate and evaluate the scientific and technological feasibility of seaweed aquaculture within the Port. This project will blend field surveys, controlled lab and field trials, with regular knowledge-exchange with the MHPA and other stakeholders.
Swansea University is a UK top 30 institution for research excellence (Research Excellence Framework 2014), and has been named Welsh University of the Year 2017 by The Times and Sunday Times Good University Guide.
The studentship covers the full cost of UK/EU tuition fees, plus a stipend. The bursary will be limited to a maximum of £14,198 p.a. dependent upon the applicant’s financial circumstances

Applicants are strongly advised to contact Prof. Kam W. Tang or Dr. Sara Barrento regarding information on the area of research, particularly via email (firstname.lastname@example.org; email@example.com). Applicants are also advised to contact Alaric Churchill regarding the commercial aspects of the project (Alaric.firstname.lastname@example.org).
We aim to link PhD students and Post-docs who research all types of algae. From micro to macroalgae there will be key note speakers, flash talks and poster presentations on a variety of topics within algal research as well as a tour of the facilities, networking, conference dinner and more.
Swansea University invites you to attend the 7th UK Algae Conference:“The best of both worlds- combining ideas from micro-and macro algae research” on the 6th and 7th of July, sponsored by Phyconet.
The event is open to all algae community members: associations, SMEs, stakeholders, academics, post-graduate students.
rebranding macroscopic, multi-cellular marine algae
Dr Sara Barrento recently presented a CoS lunchtime talk about the emergence of the sea vegetables. CoS Lunchtime Talks is an event run by the Colledge of Science at Swansea University, aiming to bring together each department of the college to discuss their research, combine expertise, and perhaps collaborate. You can see her presentation below.
in Journal of Applied Phycology the paper with the title:
Bioremediation efficacy—comparison of nutrient removal from an anaerobic digest waste-based medium by an algal consortium before and after cryopreservation
An algal consortium was isolated from an integrated steelmaking site at TATA Steel Strip Products Ltd. in Port Talbot, UK, and its bioremediation capacity tested. Excellent “bioremediation” was observed when the mixed culture was “applied” to diluted effluent from an enhanced anaerobic digestion plant at Dŵr Cymru Welsh Water at Port Talbot, UK. After 5 days of cultivation in a 600-L photobioreactor, 99% of the total nitrogen (initial level, 4500 μmol L−1) and total phosphorus (initial level, 690.4 μmol L−1) were removed from the waste stream. The consortium was deposited in the Culture Collection of Algae and Protozoa (CCAP), an international depository authority for microalgal patents, as CCAP 293/1. This material has been successfully cryopreserved using a two-step cryopreservation protocol with dimethyl sulphoxide (5% v/v) used as a cryoprotectant. On recovery of samples after 3 months storage at −196 °C, the specific bioremediation activity of the revived consortium was tested. The capacity of the revived culture to bioremediate effluent was not significantly different (p < 0.05) from a non-cryopreserved control, with 99% of total nitrogen and phosphorus remediated by day 4. Although non-axenic algal cultures have previously been cryopreserved, this is the first report of the successful cryopreservation of mixed algal consortium, with validation of its ability to bioremediate after thawing comparing non-cryopreserved cultures with a revived post-thaw algal consortium. The study also highlights the need to ensure the long-term security and the requirement to validate the functionality of conserved inocula with biotechnological/bioremediation potential.
During last week (13.02.17-17.02.17), part of Swansea University team of PhycoPigment project (Innovate Uk- Newton-CONACYT), Dr Claudio Fuentes-Grunewald and Dr Bob Lovitt visited INECOL and Tecnológico de Monterrey facilities in Mexico. It was the first face to face meeting with our Mexican colleagues and it was a great opportunity to discuss latest results of our experiments.

La Cité Nantes Events Center will host the 6th ISAP congress from the 18th to 23rd of June 2017 at Nantes (Western France).
“Previous ISAP Congresses have seen the role of applied algal biotechnology and their potential developed in a commercial, remedial or regulatory context. In 2017 the scope of the 6th edition of ISAP congress is to appreciate the huge phycological biodiversity and the diversity of its biotechnological applications through the prism of a new and promising industrial sector in full development. The Congress will include speakers and posters presentations, exhibitors and for the first time a BtoB session to meet the right partners.”
The early bird registration is now opened and will close on the 15th of March.
Taylor & Francis selected as a highlight a review published by Dr Carole Llewellyn (AlgaeWales team member) in the European Journal of Phycology on Cyanobacterial metabolites as a source of sunscreens and moisturizers.
The article is now trending and reviews the diverse beneficial impacts of cyanobacterial metabolites and emphasize on the many oppurtinuties to use these high value products in cosmetics which is a booming industry for the use of Algae.

The recognition that ultraviolet radiation has harmful effects on the skin has led to the commercial development of inorganic and synthetic organic UV filters that can reduce the negative effects of exposure to sunlight. In addition, moisturizing chemicals are extensively used in personal care products to improve the ability of skin to retain water. Whilst current UV filter and moisturizing chemicals have clear beneficial qualities, they may also have adverse effects such as contact sensitivity, oestrogenicity and even tumorigenic effects on human skin. Furthermore, the accumulation of these chemicals in the aquatic environment could be potentially harmful. Consequently, there is interest in exploiting safer alternatives derived from biological sources, especially from photosynthetic organisms such as cyanobacteria which have developed mechanisms for coping with high UV irradiation and desiccation. In order to overcome the detrimental effects of UV radiation, these microorganisms produce UV screening compounds such as mycosporine-like amino acids and scytonemin, which are good candidates as alternatives to current synthetic UV filters. In addition, extracellular substances produced by some extremophilic species living in hyper-arid habitats have a high water retention capacity and could be used in cosmetic products as moisturizers. In this review, we present an overview of the literature describing the potential of cyanobacterial metabolites as an alternative source for sunscreens and moisturizers.
The British Phycological Society in association with the Marine Biological Association of the UK will be running a COURSE on COLLECTING AND IDENTIFYING SEAWEEDS.
