Dr Jeyamalar Jeyanathan from Ghent University, Belgium, has requested access to cultures of Methanomassilicoccales. Peter Janssen suggests that we supply her with cultures of ISO4-H5 and ISO4-G1 for use in her research programme which is investigating a plant-based additive to reduce the methane production. Jeyamalar originally isolated these cultures during her work at AgResearch under PGgRc METH0701. The genomes of these cultures are published, and AgResearch has an obligation to supply these to researchers who request them. The cultures are under the control of PGgRc as part of AgResearch IP brought into the PGgRc.
