tehniskais glicerīns Bioloģija fermentācijas gāzes AMPTS metāns

description

Darbā analizētas anaerobās fermentācijas gāzes, izmantojot automātisko metāna potenciāla mērīšanas sistēmu. Salīdzināta tehniskā un analītiskā glicerīna izmantošana par substrātu. Izmantojot automātisko metāna potenciāla mērīšanas sistēmu AMPTS II, tika reģistrēts ne tikai metāns, bet gan visu gāzu kopīgais tilpums, izņemot CO2, tādēļ veiktas papildus analīzes gāzu sastāva noteikšanai, izmantojot gāzu hromatogrāfiju – masspektrometriju. Noskaidrots, ka Enterobacter aerogenes nozīmīgi palielināja ūdeņraža saturu tehniskā glicerīna fermentācijas gāzēs. Analītiskā glicerīna fermentācijā tika iegūts par 37 līdz 211 % vairāk gāzes nekā tehniskā glicerīna fermentācijā līdzīgos apstākļos. Anaerobās fermentācijas process raksturots arī ar pH izmaiņām, ķīmisko skābekļa patēriņu un mikroorganismu kolonijas veidojošo vienību skaitu. Šajā darbā tiek sniegts arī teorētisks ieskats par metānu, tehnisko glicerīnu un gāzu analīzes metodēm.
