Microbial fatty acids and thermal adaptation.
The models presented enable the prediction of temperature-induced changes occurring in the fatty acids of microorganisms, and enzymatic steps of the fatty acid biosynthesis that possibly are under temperature control. Expand
Temperature adaptation in yeasts: the role of fatty acids.
Within temperatures permitting growth, there were no changes in the major fatty acids of any of the yeasts, but the absolute amounts and relative compositions of the fatty acids did alter. Expand
Occurrence of nitrifying bacteria and nitrification in Finnish drinking water distribution systems.
The results showed that nitrifying bacteria are common in boreal drinking water distribution systems despite their low temperature, and the problems with nitrite accumulation are rare in Finland. Expand

Both primer sets proved to be specific for streptomycetes, and applicable for the detection of streptometes in environmental samples. Expand
Temperature adaptation in Lactobacillus fermentum: interconversions of oleic, vaccenic and dihydrosterulic acids.
The interchange of octadecenoic acids and dihydrosterulic acid was a response of aerobically growing Lactobacillus fermentum to changes in growth temperature, showing mirror image behaviour and a temperature-dependent shift from vaccenic to oleic acid synthesis. Expand
Mycobacterium palustre sp. nov., a potentially pathogenic, slowly growing mycobacterium isolated from clinical and veterinary specimens and from Finnish stream waters.

- 1 September 2002
Taxonomic studies were performed on a phenotypically homogeneous group of 13 mycobacteria isolated from clinical, veterinary and stream-water samples and indicated that the novel isolates represent a previously undescribed species, for which the name Mycobacterium palustre sp. Expand
Temperature shifts in regulation of lipids accumulated byLipomyces starkeyi
The temperature profile for the highest lipid yield with the most desired composition should be: (i) a growth phase temperature that gives the maximum growth rate and (ii) an accumulation phaseTemperature that produces the desired ratio of palmitic to oleic acid. Expand
The relation between growth of four microbes on six different plasterboards and biological activity of spores.
It is suggested that both the microbial growth on plasterboard and the resulting bioactivity of spores vary and might be affected by changing the growth conditions provided by the plasterboards. Expand
The Microbial Community Structure of Drinking Water Biofilms Can Be Affected by Phosphorus Availability

- 1 January 2002
Differences in community structures between biofilms and drinking and warm waters can be assumed from PLFAs and LPS 3-OH-FAs, concomitantly with adaptive changes in fatty acid chain length, cyclization, and unsaturation. Expand
