Nomenclatural note
Dates and page numbers vary: 1843: 128; 1844: 158 (Index Nominum Algarum); 1843: 128 (Silva et al. 1996); 1844: 158 (Womersley 1996). - (12 May 2009) - G.M. Guiry

Taxonomic note
According to Silva et al. (1996: 184), the name Delisea fimbriata has been misapplied to this species by Levring (1953: 521, 523-526, figs. 52-55A,B) - (11 May 2006) - G.M. Guiry

Distributional note
According to Fuhrer (1981) this species occurs in temperate and subtropical waters. Huisman (2000) notes that this species is distributed from Dongara, Western Australia, around southern Australia to Caloundra, Queensland. - (11 May 2006) - G.M. Guiry

Usage note
This species avoids a broad spectrum of bacterial infections without breeding any bacterial resistance to its defensive chemistry. Molecules known as furanones produced that bind readily to the specific protein-covered bacterial receptor sites. These receive the bacterial signaling molecules (N-acyl homoserine lactone) that normally induce surface colonization. This method of blocking bacterial communication effectively prevents bacteria from forming groups and becoming virulent, but does not physically kill them. More than 80% of bacterial infections in humans are estimated to involve the formation of bacterial colonies, or biofilms, while numerous other potential applications for this completely novel anti-bacterial technology exist. BioSignal Ltd., an Australian company, is now testing and/or already applying synthetic furanones based on those produced by Delisea pulchra in a variety of applications, including medical treatment and devices; pipelines; heating, ventilating, and air conditioning systems; cleaning products; and water treatment. - (04 January 2010) - M.D. Guiry
