Whakamahinga Hua
I whakamahia te waikawa 4-Methoxybenzoic i roto i te waikura me te whakaheke o te cytochrome c i roto i te otinga na roto i nga rereke rereke-whakahuihui takitahi i runga i nga hiko koura ma te whakamahi i te voltammetry hurihanga. Koia anake te puna waro me te kaha mo te tipu o nga ahurea o Nocardia sp. DSM 1069. Whakaahuatanga Ko te waikawa Anisic he waikawa methoxybenzoic ranei he puhui waro he waikawa warowairaka. Ko te waikawa P-Anisic, e mohiotia ana ko te waikawa 4-methoxybenzoic, te waikawa Draconic ranei, he waikawa methoxybenzoic kua whakakapihia ki te roopu methoxy i te waahi C-4, me te waikawa P-Anisic he waikawa waro me te reka reka. Koia tetahi o nga inemate (waikawa m-anisic, me te waikawa o-anisic) o te waikawa anisic. Ka whakamahia te kupu waikawa anisic hei whakaahua i te waikawa p-anisic me te waikawa P-anisic ka puta mai i te waikura o te p-cresyl-methyl ether. Ko te waikawa P-Anisic he waikawa carboxylic e kitea ana i roto i te anihi, he tipu puāwai i te whanau Apiaceae. Ko te waikawa P-Anisic he totoka kiriata ma e kore e rewa i roto i te wai, tino memeha i roto i te waipiro, me te wairewa ki te ether.
