  • Patent number: 11939576
    Abstract: The present invention provides non-propagating transgenic microalgae expressing at least one heterologous RNAi molecule. The RNAi-expressing non-propagating transgenic microalgae are used for oral delivery of the RNAi molecule to a target organism in its intact and functional form. The heterologous RNAi molecule, present within the microalgae, is characterized by being biologically active, exerting at least one specific effect on the organism consuming the microalgae or on a pathogen of said organism. In particular, the non-propagating transgenic microalgae are used as agents for biological control of animal and plant pests.

  • Publication number: 20100068721
    Abstract: Virus contaminations of bioreactors can cause considerable losses in the industry and prevention of such contaminations is usually a major concern, especially in continuous cultures and particularly in outdoor/uncovered operations such as ponds or “racing ponds”. Use of transgenic algae/cyanobacteria harboring introgressed virus/phage DNA fragments, cultured in these bioreactors/ponds will provide protection to a range of viruses/phages. Molecular mechanisms such as lysogeny and post transcriptional gene silencing (PTGS) are being exploited to produce protected algae/cyanobacteria with cross protective resistance against various viruses/phage, thus gaining bioreactor stability.
