Lactose plays a crucial role in controlling milk volume by inducing water toward into the mammary secretory vesicles from the mammary epithelial cell cytoplasm, thereby maintaining osmolality. In current study, we determined the expression of several lactose synthesis related genes, including glucose transporters (glucose transporter 1, glucose transporter(More)
The enzymatic properties of four lipases (A, B, C and D) from different strains of Aspergillus niger, were investigated, and a 3-factor mixture design and triangular surface analysis were performed to screen the optimal combi-lipase by observing synergistic effects. Lipases B and D differed in optimal pH, temperature and substrate specificity. A(More)
Mammalian milk is a key source of lipids, providing not only important calories but also essential fatty acids. Veterinary medicine and omics systems sciences intersection, termed as "veterinomics" here, has received little attention to date but stands to offer much promise for building bridges between human and animal health. We determined the changes in(More)
Relatively poor heterologous protein yields have limited the commerical applications of Galactomyces geotrichum lipase I (GGl I) efficacy trials. To address this, we have redesigned the GGl I gene to preferentially match codon frequencies of Pichia pastoris (P. pastoris) while retaining the same amino acid sequence. The wild type and codon optimised GGl I(More)
