Abstract: The composition comprises of a component A selected from a hydroxylated derivative of benzoic acid or of cinamic acid, their esters, amides or salts, a glycoside of a hexose, and their mixtures; and a component B selected from quinic acid, shikimic acid, their alkaline metal or alkaline earth salts, their methyl esters, and mixtures of the same. This composition is suitable for protecting the skin against ultraviolet radiation coming from the sun or artificial sources, such as those used in phototherapy units and in sun tanning rooms. For application in the field of dermatology and nutrition, and, in particular, in the photoprotection of the skin and mucosa, photo-ageing and photocarcinogenesis, including protection of the immune system associated with the skin.

Abstract: Phosphorylated glucomannan polysaccharide compositions are shown to effectively enhance healthy immune function. Dosage forms including pills, sprays, functional foods and cosmetics may achieve this benefit while being essentially free of storage protein from nongerminated seeds of Ricinus communis.

Abstract: The process to produce heterologous proteins in a minimal culture medium consists of (i) transforming a bacterial strain that is secretary in a minimal culture medium with a plasmid that contains the coding sequence of said heterologous protein, (ii) culturing said strain in a minimal culture medium, and (iii) recovering the heterologous protein. The bacterial strain that is secretary in a minimal culture medium can be obtained by means of a process that comprises (a) transforming bacteria adapted to grow in a minimal culture medium with a plasmid that comprises a DNA sequence that encodes for a protein that is toxic for a bacteria when it accumulates in the cytoplasm and whose synthesis is coupled to the secretion into the periplasm, (b) culturing said transformed bacteria in a minimal culture medium, and (c) selecting the surviving bacteria. It is applicable in the production of proteins of interest in bacteria that are secretary in a minimal culture medium.
