BackgroundThe marine alga Ulva compressa is the dominant species in coastal areas receiving effluents from copper mines. The alga can accumulate high amounts of copper and possesses a strong antioxidant system. Here, we performed short-term transcriptomic analyses using total RNA of the alga cultivated with 10 μM of copper for 0, 3, 6, 12 and 24 h by RNA-seq.ResultsDe novo transcriptomes were assembled using the Trinity software, putative proteins were annotated and classified using Blast2GO. Differentially expressed transcripts were identified using edgeR. Transcript levels were compared by paired times 0 vs 3, 0 vs 6, 0 vs 12 and 0 vs 24 h at an FDR < 0.01 and Log2 Fold Change > 2. Up-regulated transcripts encode proteins belonging to photosystem II (PSII), Light Harvesting II Complex (LHCII), PSI and LHCI, proteins involved in assembly and repair of PSII, and assembly and protection of PSI. In addition, transcripts encoding enzymes leading to β-carotene synthesis and enzymes belonging to the Calvin-Benson cycle were also increased. We further analyzed photosynthesis and carotenoid levels in the alga cultivated with 10 μM of copper for 0 to 24 h. Photosynthesis was increased from 3 to 24 h as well as the level of total carotenoids. The increase in transcripts encoding enzymes of the Calvin-Benson cycle suggests that C assimilation may also be increased.ConclusionsThus, U. compressa displays a short-term response to copper stress enhancing the expression of genes encoding proteins involved in photosynthesis, enzymes involved carotenoids synthesis, as well as those belonging to the Calvin-Benson cycle, which may result in an increase in C assimilation.Electronic supplementary materialThe online version of this article (10.1186/s12864-018-5226-4) contains supplementary material, which is available to authorized users.

“…Several microalgae species extracts are widely applied in cosmetic-based industries, especially for skincare products. These include face and skincare (anti-ageing cream, emollient, anti-irritant in peelers, refreshing care, sunscreens) as well as hair care products [ 143 ]. Among the common microalgae species include Arthrospira sp., C. vulgaris, D. salina, S. platensis, Chondrus crispus, Mastocarpus stellatus, Ascophyllum nodosum, Alaria esculenta and N. oculate [ 144 ].…”

Microalgae are known as a rich source of bioactive compounds which exhibit different biological activities. Increased demand for sustainable biomass for production of important bioactive components with various potential especially therapeutic applications has resulted in noticeable interest in algae. Utilisation of microalgae in multiple scopes has been growing in various industries ranging from harnessing renewable energy to exploitation of high-value products. The focuses of this review are on production and the use of value-added components obtained from microalgae with current and potential application in the pharmaceutical, nutraceutical, cosmeceutical, energy and agri-food industries, as well as for bioremediation. Moreover, this work discusses the advantage, potential new beneficial strains, applications, limitations, research gaps and future prospect of microalgae in industry.

“…In a review by Mourelle and colleagues, cosmetics are defined as products aimed for improving skin appearance, structure and morphology in assistance of excipients and active ingredients specifically suited for various skin types [145]. Several microalgae species extracts are widely applied in cosmetic-based industries, especially for skincare products [146]. These include face and skincare (anti-ageing cream, emollient, anti-irritant in peelers, refreshing care, sunscreens) as well as hair care products [146].…”
