Desaturase genes in a psychrotolerant Nostoc sp. are constitutively expressed at low temperature
Antarctic psychrotolerant, Nostoc sp. (SO-36), when grown at 25 °C and then shifted to 10 °C, showed an increase in the tri-unsaturated fatty acid [C 18:3(9,12,15) ] at the expense of mono- [C 18:1(9) ] and di-unsaturated [C 18:2(9,12) ] fatty acids. These results indicate that the activities of the...
