The present invention relates to a host cell, which comprises under the control of a heterologous promoter a polynucleotide comprising a nucleotide sequence encoding a polypeptide capable of synthesizing a polysaccharide consisting of a dimeric repeating unit as well as to a vaccine composition comprising such host cell. Furthermore, either such host cell or a polypeptide expressed by such host cell is used for the production of a polysaccharide consisting of a dimeric repeating unit which may be used as a glycoconjugate vaccine.

Described is a method to transfer chromosomal DNA between two microbial species without genetic engineering or vectors. The strains resulting from this method are chimeric microbial hybrids that can express a combination of genotypes from both parents.

The invention relates to bacterial artificial chromosomes (BAC) comprising retroviral nucleic acid sequences encoding: gag and pol proteins, and an env protein or a functional substitute thereof, wherein each of the retroviral nucleic acid sequences are arranged as individual expression constructs within the BAC. The invention also relates to uses and methods of transient transfection using said BAC.

The invention comprises a photoautotrophic organism, generally having simpler nutritional requirements than heterotrophic organisms, utilized as a chassis for the heterologous expression and function of enzymes, or derivatives of said enzymes, that show activity toward the degradation/detoxification of toxins known to be associated with and specific to harmful algal blooms. As an example, a cyanobacterial strain (Synechocystis sp. PCC 6803) modified to express Sphingomonas sp. USTB-05 MlrA enzyme functionality, showing the capability of degrading microcystins (results shown here) and nodularins, is presented. Under modelled natural conditions, results indicate that heterologous enzymatic activity against microcystin-LR is more stable over time when utilizing a photoautotrophic chassis in comparison to use of a heterotrophic bacterial strain. In addition, both the viability and cell density of the photoautotrophic host is maintained for a significantly longer period of time, compared to a heterotrophic host.
