Saldūdens dūņu mikroorganismu populāciju dinamika jēlglicerīna fermentācijas laikā

2019

Anaerobās fermentācijas ceļā var lietderīgi izmantot jēlglicerīnu, biodīzeļa ražošanas blakusproduktu, iegūstot produktus ar pievienotu vērtību, kas ļauj padarīt biodīzeļa ražošanu ekonomiski izdevīgāku. Šajā darbā tika pētīta mikroorganismu populāciju dinamika jēlglicerīna anaerobās fermentācijas laikā, izmantojot saldūdens dūņas kā inokulātu. Fermentāciju veica 20°C un 37°C temperatūrā 4 un 8 dienas. Noteica izdalītās gāzes tilpumu, kā arī barotņu organisko vielu daudzumu un sastāvu, nosakot ķīmiskā skābekļa patēriņu un veicot šķidruma hromatogrāfiju. Pētīja mikroorganismu populāciju dinamiku, veicot qPCR ar dažādiem baktēriju taksoniem specifiskiem 16S rDNS praimeru pāriem, kā arī veicot…
