Structural characterization of bacterial proteins involved in antibiotic resistance and peptidoglycan biosynthesis
This thesis describes the structural and biochemical characterization of the β-lactamase BlaC from Mycobacterium tuberculosis (Mtb), and the Alr and YlmE proteins from Streptomyces coelicolor A3(2).Mtb is the main cause of tuberculosis.

after activation with the bacterial cell wall derivative liposomal muramyl tripeptide in combination with interferon-gamma
CONCLUSION: This study demonstrates that human macrophages can be induced to exert direct anti-tumor activity against osteosarcoma cells. Our observation that the induction of macrophage anti-tumor activity by L-MTP-PE required IFN-gamma may be of relevance for the optimization of L-MTP-PE therapy in…

Nano shapes micro : Impacts of metallic nanoparticles on microbial communities
This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

Effect of Nanoparticles on Microbial Catabolism and Community Structure using Biolog techniques
1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

Bacteriën bevriezen en fotograferen
Hoe weet een bacterie waar er voedsel is in zijn omgeving? En hoe beweegt die bacterie vervolgens naar dat voedsel toe? Hoogleraar Ultrastructuurbiologie Ariane Briegel nam het publiek mee op een microscopische reis tijdens haar lezing ‘Zooming in on bacterial behaviour’ voor het Natuurwetenschappelijk…

Vijftig Tinten Stress
De uitdaging: een tool ontwikkelen die chemische stoffen detecteert die op zichzelf niet-dodelijke stress geven aan bacteriën, maar gecombineerd wel dodelijk zijn. Een team van dertien Leidse studenten nemen deze uitdaging aan in de jaarlijkse ‘international Genetically Engineered Machine’ (iGEM) competitie…
