Abstract: An embodiment concerns a container for tobacco articles, each tobacco article comprising a filter; the container comprising: an outer box; an inner liner inserted in the outer box and configured to receive tobacco articles, the inner liner defining an internal surface designed to be in contact with the tobacco articles and an external surface in contact with the outer box; wherein at least one surface of the inner liner is coated with an anti-staining coating comprising a first anti-staining layer comprising ethyl cellulose to prevent or minimize staining from oily chemical substances contained in the filters of the tobacco articles.

Abstract: A process for the production of hyaluronic acid by continuous fermentation of Streptococcus in a chemostat culture gives high yields of high molecular weight hyaluronic acid uncontaminated by toxic impurities. The process is advantageous in that it solves the problem of traditional batch cultures in which degradation enzymes can begin to break down the cell walls of Streptococcus releasing cells contents into the fermenter broth complicating the purification of high molecular hyaluronic acid.

Abstract: A process for the production of hyaluronic acid by continuous fermentation of Streptococcus equi in a chemostat culture gives high yields of high molecular weight hyaluronic acid uncontaminated by toxic impurities. The process is advantageous in that it solves the problem of traditional batch culture in which degradation enzymes can begin to break down the cell walls of Streptococcus releasing cell contents into the fermenter broth, leading to purification difficulties.
