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.

摘要:A synthesis method for carbazole phosphazene based polymer and a method for the recovery of precious metal elements from electronic waste materials are provided. The developed method allows for the efficient and cost-effective synthesis of carbazole phosphazene based polymer in a single step, with high yield and easy purification. In the method for the recovery of precious metal elements from electronic waste materials, a two-step metal leaching process is employed using solutions with different acidity levels, resulting in the high-efficiency recovery of precious metal elements. The carbazole phosphazene based polymer represented by Formula 2 exhibits high selectivity in the adsorption of precious metal elements, particularly gold. Therefore, it can be applied in the recovery of gold and other precious metals from electronic waste materials in the method for the recovery of precious metal elements.

摘要:The invention relates to a method for the synthesis of two isomers, at function OH, alone or in mixtures, of amino acids α or the derivatives thereof, having general formula (B), wherein: linkage C—O of the 4-position carbon (represented by symbol) denotes one or other of isomers III or IV, or mixtures thereof. Moreover, R 1 and R 2 represent: a hydrogen atom; or either R 1 or R 2 represents a hydrogen atom and the other substituent is a radical R a , an acyl group —COR a , such as acetyl, or a functional group —COOR a , —SO 2 R a , —N (R a , R b ), R a and R b , which are identical or different, representing a C1-C12 linear or branched alkyl radical, optionally substituted, an aryl group with one or more aromatic rings and heterocycles, comprising between 5 and 8C, optionally substituted, or aralkyl, the alkyl substituent and the aryl group being as defined above; or R 1 and R 2 both represent a substituent as defined above. R 3 represents a hydrogen atom or R a and R 4 has the significance of R a . The invention is characterised in that it comprises: the isomerisation of a compound having formula (I), wherein R 1 , R 2 , R a , R 3 and R 4 are as defined above, such as to produce a compound having formula (II); and the reduction of the carbonyl function thereof which, depending on the catalytic system employed and the formula (I) compound used, produces one of the isomers having general formula (III) or (IV) or a mixture thereof having formula (B). The invention can be used for the synthesis of (2S, 3R, 4S)-4-hydroxyisoleucine.
