“…Seaweed also brings another benefit, i.e. as the source of biodiesel and bioenergy (Bruhn et al, 2011;Borines, de Leon & Cuello, 2013;Jaap et al, 2014;Bharathiraja et al, 2015;Ghadiryanfar, Rosentrater, Keyhani & Omid, 2016;Jiang, Ingle & Golberg, 2016). According to the result of the study, seaweeds of high economic value and is potential to be cultivated in Indonesian water as producers are among others Gracilaria as agarophyte producer, Eucheuma and Kappaphycus as carraginophyte producers, and Sargassum and Turbinaria as alginophyte producers (DoMF Sulteng, 2009).…”

Seaweed is a promising fishery product. Potential aquaculture of which in Lampung Province is estimated around 2260.5 ha. Several seaweed farming efforts have been carried out in Lampung Bay (Indonesia). However, they faced failure. Therefore, it is necessary to carry out spatial analysis to understand the level of seaweed farming suitability in the bay. This study was carried out in five observation site groups with total 20 sampling points and employed survey through spatial and temporal approaches as the study method. Geo-statistical model was used for earth surface mapping, both for biotic and abiotic components. Each station was then be given value to determine suitability class. The class was determined by making aquatic suitability matrix for each physical, chemical and biological parameter. Results acquired indicate that Lampung Bay area is not suitable as seaweed farming site. However the area is open for any suggestion.

“…This builds on published research (Adams et al 2015) which identified the washing of all types of macroalgae to be a common practice in laboratory scale experiments on macroalgae, with examples including Bruhn et al (2011), Wang et al (2011), Meinita et al (2012 and Park et al (2012). On an industrial scale, the use of large quantities of fresh water and the logistics regarding handling could benefit some species and downstream processes, but as it also removes glucose and subsequently has a negative effect on ethanol yields (Adams et al 2015) it is important that more data regarding unwashed macroalgae should be available to inform both industry and academia.…”

Macroalgae are capable of generating more organic carbon per hectare than terrestrial plants without requiring land, fertiliser or fresh water to grow. In addition, they avoid the food versus fuel argument as they are not a major food source in Europe. In spite of these benefits, macroalgae are not yet fully exploited as a biomass source for bioenergy or platform chemical production in Europe, with one issue being the high harvesting and processing costs. This paper considers the impact of mechanical pre-processing of Laminaria digitata combined with different drying techniques and the effect of these on downstream processing to bioethanol. Results show that mechanically screw pressing macroalgae does enhance conversion to ethanol, but only when the material contains low levels of storage carbohydrates. This occurs in freezedried and air-dried samples. The addition of a press aid in the mechanical pre-processing step increases ethanol yields per gramme macroalgae, but due to the presence of the unutilised press aid in the fermentation, ethanol yields were lower overall. The two main findings from this work were (1) simple mechanical processing of L. digitata provides homogenisation and pumpability of macroalgae without negatively affecting subsequent microbial conversion to ethanol. (2) At higher carbohydrate concentrations, screw pressing confers no advantage in ethanol yields over strips of unprocessed kelp, making strips the more viable conversion option for low-input, large-scale processing.

“…The cosmopolitan nature of Ulva spp., its development patterns and plasticity, among other reasons make it a good model organism to study algal growth, development and morphogenesis [6]. From an economic perspective, the use of Ulva species for different applications has been largely described: bioremediation [7], bioenergy [8], food and feed [9]. A biorefinery approach for industrial exploitation of Ulva constituents have been proposed [10].…”

With the emergence of new diseases, the increase of pathogenic strains resistance and the apprehensiveness of synthetic compounds side effects, there is a constant need to find natural and low toxicity drug candidates. Seaweeds are rich source of original and bioactive natural substances. In particular, species of the genus Ulva have been demonstrated to metabolize biomolecules with pharmacological potential. This mini review present some of the biological properties reported for Ulva spp.
