Boraiy, Logeina ; Schmid, Sergio (Dir.)

Mémoire de bachelor : Haute Ecole d'Ingénierie, 2018.

The aim of this work is to identify the microbiota of Paracentrotus lividus with the 16S rDNA method and to verity if they produce biologically active molecules with antimicrobial and embryological assays.

Isolation and characterization of sea urchin P.lividus microbiota from coelomic fluid : bachelor's thesis : diploma 2016

Zuber, Boris ; Schmid, Sergio (Dir.)

Mémoire de bachelor : Haute Ecole d'Ingénierie, 2016.

The identification of the microbiota present in the coelomic fluid of Paracentrotus lividus has been highlighted in order to understand the role of bacteria in the physiology, ecology and aquaculture activities of this echinoderm.

Strategies for the study of the trpX role in Streptomyces coelicolor = Stratégies pour l’étude du rôle du gène trpX dans la souche Streptomyces coelicolor

Ledda, Mirko ; Schmid, Sergio (Dir.)

Mémoire de diplôme HES : Haute Ecole d'Ingénierie, 2007.

The emergence of several pathogenic bacteria and the adaptation of part of those resistant to antibiotics currently used, in clinically treatments, needs the research for new antibiotic development and the creation of a “Superhost”, allowing a large scale production of antibiotics. Streptomyces belongs to Actinomycetes , a group of gram-positive bacteria, producing more than 50% of known...

Identification of the genetic elements involved in pediocin PD-1 synthesis = Identification des éléments génétiques impliqués dans la

Dumas, Stéphane ; Schmid, Sergio (Dir.)

Mémoire de diplôme HES : Haute Ecole d'Ingénierie, 2007.

Aim: Confirm the presence of pedA gene, known part of pediocin PD-1 operon, in one of Pediococcus damnosus plasmids. Construct a plasmid library using this isolated plasmid, digested with endonucleases and subcloned in pZErO-2 vector. Identify recombinant plasmids containing pedA gene by PCR screening or/and by hybridization with pedA probe. Sequence the insert and localize pedA region in order...
