摘要:
The present invention relates to a method for producing cheese with good flavour, especially low-salt cheese by using a lactic acid bacteria (LAB) starter culture which is glutamate decarboxylation (GAD) negative. The method may additionally involve inoculating the milk substrate with a GAD-negative Lb. helveticus strain having a high lytic and peptidolytic activity, which further releases glutamate into the milk Additional application of camel chymosin reduces bitterness.
摘要:
The invention relates to polypeptides having glucanase, eg endoglucanase, mannanase, xylanase activity or a combination of these activities, and polynucleotides encoding them. In one aspect, the glucanase activity is an endoglucanase activity (eg, endo-1,4-beta-D-glucan 4-glucano hydrolase activity) and comprises hydrolysis of 1,4-beta-D-glycosidic linkages in cellulose, cellulose derivatives (eg carboxy methyl cellulose and hydroxy ethyl cellulose) lichenin, beta-1,4-bonds in mixed beta-1,3-glucans, such as cereal beta-D-glucans or xyloglucans and other plant material containing cellulosic parts. In addition, methods of designing new enzymes and methods of use thereof are also provided. In alternative aspects, the new glucanases eg, endoglucanases, mannanases, xylanases have increased activity and stability at increased pH and temperature.
摘要:
This invention relates to novel mutant filamentous fungi which are deficient in the gene for the corresponding aspartic proteinase. These organisms are useful production hosts in the production of heterologous polypetides such as chymosin.
摘要:
In a process for producing cheese from milk, an inactive milk-clotting enzyme and optionally chymosin or another suitable proteolytic enzyme is added to the milk, optionally simultaneously with or after adding a starter culture, to form a curd, at least part of the inactive enzyme is activated, and the resulting curd is converted to the ripened cheese. The milk employed is preferably concentrated milk, and the inactive milk-clotting enzyme is preferably prochymosin.
摘要:
The present invention relates to methods for coagulating bovine milkand making cheese using a coagulant substantially identical to a chymosin originating from an animal of the Tylopoda suborder.
摘要:
High solubility film product comprising a starch and a cellulose and at least one bacterium or enzyme chosen from those necessary for milk fermentation, coagulation or curdling.
摘要:
L'invention concerne de nouveaux champignons filamenteux mutants présentant une carence de gêne pour la protéinase aspartique correspondante. Ces organismes sont des hôtes de production utiles dans la production de polypeptides hétérologues tels que la chymosine.
