Inter specific variability in UV-B sensitivity of Antarctic bacteria / Jan H. Vosjan, Marek K. Zdanowski.

Title: Inter specific variability in UV-B sensitivity of Antarctic bacteria / Jan H. Vosjan, Marek K. Zdanowski.
Author(s): Vosjan, Jan H.
Zdanowski, Marek K.
Date: 2001.
In: Circumpolar Journal. (2001.), Vol. 16(2) (2001)
Abstract: Presents results of study of effect of UV-B radiation on 25 psychrophilic or psychrotrophic colony-forming bacteria, with distinct ecophysiological and morphological properties, isolated from various marine habitats in Admiralty Bay and Drake Passage, Antarctica. Parameters investigated were survival, as determined by bacterial growth on solid agar; total bacterial abundance determined by acridine orange staining and epifluorescence microscopy; biovolume; ATP content; and changes in enzyme patterns. Survival rates were higher for strains isolated from water column that for those isolated from micro environments such as gut of zooplankton, faeces, sea ice and deep water; and also higher for pigmented isolates with dark orange, yellow or beige colour. ATP content per cell increased in initial phase of exposure to UV-B, and decreased rapidly thereafter, indicating inhibition of anabolic reactions with continued ATP production. Some enzymes were unaffected by UV-B radiation and some lost activity, but nitrate reduction was induced in all cases.
