Identification of PHA producing bacteria employing molecular techniques
Gajdová, Barbora ; Obručová,, Hana (referee) ; Obruča, Stanislav (advisor)
This diploma thesis deals with identification of bacteria which are capable of producing polyhydroxyalkanoates (PHAs). Work included testing variety of genera including Pseudomonas, Lactobacillus, Bifidobacterium, thermophilic cultures and samples gathered from natural sources. Bacteria were investigated by molecular technique polymerase chain reaction – PCR. An amplification of the PHA synthase gene (phaC) was analyzed. In the first reaction phaC and 16S rRNA genes were tested at the same time. 16S rRNA gene is used as control for bacterial DNA and as an identification tool for natural source samples. This multiplex PCR used multiple primers in PCR mix. Second reaction search for amplicon specific for catalysing biosynthesis mcl-PHA (phaC1). The presence of the PHA synthase gene was verified in 11 samples which were Bifidobacterium breve CCM 7825T, Lactobacillus rhamnosus CCM 1825T, Lactobacillus zeae CCM 7069T, Lactobacillus delbrueckii subsp. bulgaricus CCM 7190T, Lactobacillus plantarum CCM 7039T, Pseudomonas gessardii, Pseudomonas fulva, Arthrobacter protophormiae, Curtobacterium flaccumfaciens, Mycobacterium neoaurum and Staphylococcus lentus.
Determination of additives in multicomponent electrospinning systems
Gajdová, Barbora ; Petr, Knotek (referee) ; Knotková,, Kateřina (advisor)
This bachelor thesis deals with methods of producing nanofibres from mixture of different polymers. Different methods of preparation and production nanofibres by 4SPIN® are described in theoretical part. Experimental part deals with incorporation of additives into fibred layer. There were four different dyes used in this thesis: brilliant green, erythrosine, riboflavin and eriochrom black. UV – VIS spectrophotometry was used to measure volume of additives in nanofiber layer.
