metāla hidrīdi Ūdeņradis Bioloģija ūdeņradi producējošas baktērijas jēlglicerīns

description

Mikrobioloģiski ražojot ūdeņradi no jēlglicerīna, iegūst atjaunojamu enerģijas nesēju, kā arī lietderīgi izmanto atkritumproduktu - jēlglicerīnu. Šajā darbā pētīja baktēriju spēju izmantot vietējās biodegvielas ražotnes jēlglicerīnu ūdeņraža producēšanai, kā arī ūdeņraža uzkrāšanas iespējas hidrīdu veidojošā metāla sakausējumā, tam atrodoties barotnē ar baktērijām. Ar masspektrometriju noteica ūdeņraža daudzumu barotņu gāzes fāzē un noskaidroja, ka no izmantotajām baktērijām efektīvākās ūdeņraža producētājas no jēlglicerīna ir Enterobacter aerogenes. Kultivējot tās barotnēs ar dažādu jēlglicerīna koncentrāciju, par piemērotāko atzina koncentrāciju seši grami litrā. Izmantojot termogravimetriju un masspektrometriju, noskaidroja, ka izvēlētais metāla sakausējums spēj saistīt ūdeņradi, atrodoties vidē ar baktērijām.
