The invention discloses a novel method for producing high molecular weight sodium hyaluronate (HA-Na) with amino acid complex liquid as a nitrogen source through fermentation. In the method for producing the high molecular weight sodium hyaluronate, provided by the invention, yeast cream or yeast powder is replaced with the amino acid complex liquid as a fermentation nitrogen source of streptococcus zooepidemicus. The HA-Na with molecular weight of 2.2*10<6>D is obtained through control of a fermentation process. When the method is applied to industrial production, on the one hand, contents of hetero-protein and pigment in fermentation liquid can be effectively reduced, the step of subsequent HA-Na extraction is decreased, and the physical damage of the molecular weight of HA-Na in the fermentation liquid in the extraction process is reduced; on the other hand, the HA-Na production cost can be lowered, and the novel method has higher industrial application value. The HA-Na produced by the method has the molecular weight of 2.0-2.2*10<6>D, the alduronic acid content of 42.4-43.5%, the intrinsic viscosity of 3,064-3,115 and the protein content of 0.1%.

Combating sinus, throat, and blood infections with xylitol delivered in the mouth
InactiveUS20070293587A1Low dissolution rateReduce solubilityBiocideHydroxy compound active ingredientsChewing gumHuman mouth
A method of suppressing bacteria that cause infections of the throat, sinuses, heart and arteries, and joints (arthritis) by delivering xylitol in a human mouth. The method is effective with troches of pure xylitol or with xylitol chewing gum or liquid, provided sufficient quantities of xylitol are delivered. Streptococcus mutans and Staphylococcus aureus in the blood are important contributors to plaque in arteries and on heart valves and bacterial arthritis. For people whose blood is not already infected with significant levels of these bacteria, every day use of xylitol sufficient to suppress these bacteria in the oral cavity will reduce their risk of subsequent cardiovascular disease, arthritis, and sinus infections. Strep throat is a common throat infection caused by Streptococcus pyogenes. Frequent bathing with xylitol, such as from time release in the mouth, will speed recovery from strep throat.

Macrolide efflux genetic assembly
Macrolide resistance associated with macrolide efflux (mef) in Streptococcus pneumoniae has been defined with respect to the genetic structure and dissemination of a novel mefE-containing chromosomal insertion element. The mefE gene is found on the 5′-end of a 5.5 kb or 5.4 kb insertion designated mega (macrolide efflux genetic assembly) found in at least four distinct sites of the pneumococcal genome. The element is transformable and confers macrolide resistance to susceptible S. pneumoniae. The first two open reading frames (ORFs) of the element form an operon composed of mefE and a predicted ATP-binding cassette homologous to msrA. Convergent to this efflux operon are three ORFs with homology to stress response genes of Tn5252. Mega is related to mefA-containing element Tn1207.1. Macrolide resistance due to mega has been rapidly increased by clonal expansion of bacteria containing it and horizontally by transformation of previously sensitive bacteria.
