New Species of Bacteria Discovered in Hairspray

The AAAS (American Association for the Advancement of Science) reports that a new species of bacteria has been found which lives in and contaminates hairspray.

The results of a study published in the March issue of the International Journal of Systematic and Evolutionary Microbiology shows how industrial contamination can actually lead to the development of new organisms, or provide a medium which supports dangerous, existing bacteria.

“Contamination of cosmetic products is rare but some products may be unable to suppress the growth of certain bacteria,” says Dr Bakir from the Japan Collection of Microorganisms, Saitama, Japan. “We discovered a new species of bacteria called Microbacterium hatanonis, which we found contaminates hairspray.”

“We also found a related species, Microbacterium oxydans in hairspray which was originally isolated from hospital material. Microbacterium species have been identified in milk, cheese, beef, eggs and even in the blood of patients with leukaemia, on catheters and in bone marrow.”

The scientists looked at the appearance and diet of the bacterium, then analysed its genome to show that it is an entirely new species. “It has been named in honor of Dr Kazunori Hatano, for his contribution to the understanding of the genus Microbacterium,” said Dr Bakir.

Similar bacteria have been found to infect humans, and the goal now is to determine the clinical importance of the new species. “Further testing will establish whether the species is a threat to human health,” says Dr Bakir. “We hope our study will benefit the formulation of hairspray to prevent contamination in the future.”
