EMSL Microbiologist Contributes to the Identification of Six New Species of Hamigera


Cinnaminson, NJ

Six new species of Hamigera, a fungus closely related to Penicillium, were identified by a group of scientists including Dr. Zeljko Jurjevic, a Senior Mycologist from the corporate headquarters of EMSL Analytical, Inc. Other members of the group included molecular geneticist Dr. Stephen Peterson from the USDA, Peoria, IL, Fernando Vega from the USDA, Beltsville, MD, and Alberto Stchigel, Josep Guarro and Gerald Bills researchers from different institutes in Spain. The six new species of Hamigera were named Hamigera fusca, Hamigera inflata, Hamigera insecticola, Hamigera pallida, Hamigera paravellanea, Hamigera terricola. The discovery of these six new species helped clarify confusion over the genus Hamigera that has been unresolved for over a century. Hamigera has been isolated from the air, soil, textiles, animal dung and on certain insects. They are primarily decomposers but they can be implicated in food spoilage due to their thermo-tolerant and osmo-tolerant nature. The research has been published in the July-August 2010 issue of Mycologia, volume 102(4) pages 847-64.

“Dr. Jurjevic’s contribution to fungal taxonomy is a source of pride for us at EMSL,” reported Jason Dobranic, Ph.D., National Director of Microbiology at EMSL Analytical. “Research is continuing to improve what we know and understand about the microbes that live around us. This kind of basic research is especially important in order for us to ultimately understand the effects of microbes on indoor air quality and human health,” Dobranic continued. EMSL has been dedicated to research and development since its inception in 1981. The laboratory is one of the nation’s largest and fastest growing providers of environmental microbiology and chemistry analytical services.
