Abstract
A novel caldoactive filamentous bacterium was isolated from a New Zealand hot spring Optimum conditions for growth were pH 70 and 73°C in aerobic conditions Growth also occurred anaerobically Acetamide lactose nitrilotriacetic acid succinate and starch could all act as sole carbon source Carotenoids could be extracted and had a peak absorbance at 450 nm The organism was GramnegativeLong chains of cells were formed and showed characteristic coiling necridia and bulbs The organism is compared to other caldoactive filamentous organisms and is sufficiently different to make it probable that it represents a new taxonomic group capable of life at high temperatures
