1. A metabolically engineered cell that produces a mixture of at least four different neutral non-fucosylated mammalian milk oligosaccharides, wherein said cell:
is metabolically engineered for production of said mixture,
expresses at least two different glycosyltransferases involved in producing the mixture of at least four different neutral non-fucosylated mammalian milk oligosaccharides, wherein each of said at least two glycosyltransferases is selected from the group consisting of a galactosyltransferase, an N-acetylglucosaminyltransferase, and an N-acetylgalactosaminyltransferase, and
is capable of synthesizing at least one nucleotide-sugar, wherein each nucleotide-sugar is a donor for at least one glycosyltransferase.
