Abstract: The present invention relates to a sulphated heteropolymer polysaccharide obtainable from the order of Prasinococcales polysaccharide wherein the average molecular weight of the polysaccharide is between 1,000 and 40,000 kDa, or a fragment of for use in the treatment of skin irritation, wound repair, fibrotic conditions, keloid trait scarring or keloid scars, viral infection, as a biological carrier or scaffold or bio-lubricant; methods of preparing the same and uses thereof, such as in antiviral compositions.

Abstract: There is provided a composition comprising a polysaccharide obtainable from the microalgae, Prasinococcus capsulatus and strains related to P. capsulatus for use in the treatment of disorders of the immune system, for example in psoriasis and dermatological conditions, internal immune system disorders, in particular gut inflammatory conditions and respiratory conditions. Further, there is provided derivatives of a polysaccharide obtainable from the microalgae, Prasinococcus capsulatus or an algal strain related to P. capsulatus and the use of such derivatives in the treatment of disorders of the immune system.

Abstract: A photobioreactor comprising a receptacle with a first and a second outer side surface, wherein the receptacle is formed from a flexible, fluid-tight and transparent material, and wherein the receptacle is disposed in a rack provided with elongated, substantially vertical, support elements arranged in at least one horizontal row, whereby the support elements abut, in an alternating and supporting manner, against the first and the second outer side surfaces of the receptacle.
