摘要:The present invention relates to a cost-effective process for the synthesis of hyper-production of poly gamma glutamic acid using L-glutamic acid independent approach. Specifically, the present invention relates to the synthesis of poly gamma glutamic acid (γ-PGA) from jaggery, blackstrap molasses, and floral waste. More particularly, the present invention relates to a process for the synthesis of poly gamma glutamic acid in high yield and in the presence of Bacillus paralicheniformis NCIM 5769.

摘要:The present disclosure relates to a method for external synthesis of rare-earth oxychloride and production of rare-earth metal or alloy. The method comprises the steps of adding hydrochloric acid (HCl) to a portion of a pre-defined weight of rare-earth oxide (RE2O3) converting the portion of RE2O3 to rare-earth chloride hydrate (RECl3.xH2O). The method further comprises mixing the residual rare-earth oxide (RE2O3) with the RECl3.xH2O and heating the mixture to a temperature exceeding 300℃ to obtain rare-earth oxychloride (REOCl). The method includes making the obtained REOCl to react directly with a reductant or mixture of reductant and alloying element in a temperature of 600℃ - 1400℃ for reducing the rare-earth oxychloride (REOCl) to rare-earth metal or alloy; and upon cooling, treating the reduced mass of rare-earth metal or alloy with water and dilute acid to remove reaction byproducts such as calcium chloride (CaCl2) and calcium oxide (CaO).

标题:Process and culture composition for growth of alga and synthesis of biopolymer
发明人：SAVINS JOSEPH GEORGE; PAUL JAMES M
权利人:MOBIL OIL CORP
摘要:This specification discloses a process and a culture composition for growth of an alga and synthesis of biopolymer by the alga. The process involves growth of the alga and concomitant synthesis of the biopolymer in an aqueous culture containing as a source of phosphate for said alga dibasic sodium or dibasic potassium phosphate. The nitrogen source can be sodium nitrate or urea. Control of the pH of the culture is effected by injecting a mixture of carbon dioxide and air into the culture during growth of the alga and synthesis of the biopolymer. The carbon dioxide also serves as a source of carbon for growth of the alga and synthesis of the biopolymer and provides agitation/mixing within the culture chamber. Preferably, the mixture of carbon dioxide and air is injected continuously into the culture during the entire growth period of the alga.

标题 :Composition for stimulating the synthesis of the melanic pigment and process for obtaining it

摘要:This invention relates to the field of human medicine, more specifically to dermatology, and in particular to a composition developed for the stimulation of the synthesis of the melanic pigment of the skin, therefore useful for the treatment of vitiligo. The technical goal of this invention is to provide a composition of natural origin useful in the treatment of vitiligo that has no toxic effects and no relapse. The composition obtained stimulates the synthesis of the melanic pigment of the skin and the reproduction of melanocytes, as demonstrated through pharmacological tests to which the composition was subjected, causing no serious secondary reactions at all, as demonstrated in the toxicological, teratological and clinical tests performed. The resulting product can easily be obtained and applied, repigmentation begins rapidly after initiating the treatment, and the effect is irreversible. The color acquired is identical to the color of the normal skin areas of the patient, but these areas do not further increase the intensity of their coloration after the product has been applied. The product can also be used for the treatment of any depigmentation process of the skin, for example, that caused by burns.
