Abstract: The present disclosure relates to a method for the production of a human milk oligosaccharide (HMO) blend with LNFP-I and 2′-FL as the predominant HMO's, the method comprising the steps of providing a genetically engineered cell, which comprises a heterologous β-1,3-N-acetyl-glucosaminyltransferase protein, a heterologous β-1,3-galactosyltransferase protein, a heterologous α-1,2-fucosyltransferase protein, and expresses functionally the colanic acid gene cluster, comprises a native or heterologous regulatory or episomal element for controlling the expression of the proteins and optionally express a heterologous sugar transporter, and culturing the cell in a suitable cell culture medium to express said proteins and to produce an HMO blend.

Abstract: This invention relates to a method of producing mixtures of various human milk oligosaccharides (HMOs) with unique HMO blend profiles, consisting predominantly of LNFP-I and LNT and of other HMOs in less significant amounts. The less abundant HMOs might be 2′-FL, LNT-II or DFL. The strategies for achieving specific HMO blends include strain engineering and fermentation methods.

Abstract: A feed control system and related methods for a heterologous product, such as a human milk oligosaccharide, fermentation system are disclosed. The feed control system comprises a feed controller. The feed controller comprises a processor and an interface. The processor is configured to obtain a biomass content in a fermentation broth. The processor is configured to determine a carbon input parameter based on the biomass content. The processor is configured to control a carbon input to the fermentation broth according to the carbon input parameter.
