Abstract
Genomes of the month
Six new bacterial genomes have been published since last month's Genome Update. The list is shown in Table 1 and includes a species that can grow happily in a refrigerator (the δ-proteobacterium Desulfotalea psychrophila, with an optimal growth temperature of 10 °C, although it can grow at temperatures slightly below freezing!) and the actinobacterium Propionibacterium acnes, which can cause acne in humans. Let us hope that these two never cross, because the thought of a fridge with complexion problems is not very pleasant! The other genomes include that of the actinobacterium Leifsonia xyli, those of the firmicutes Mycoplasma mobile and Streptococcus pyogenes and that of an α-proteobacterium, Rickettsia typhi. A brief overview of each of these genomes is given below.
