Abstract:

The main goal of this thesis was to design and implement a tool that would be able to classify the sequences of the 16S rRNA gene into taxonomic categories using the properties of the 16S rRNA gene. The created tool analyzes all input sequences simultaneously, which differs from common classification approaches, which classify input sequences individually. This tool relies on the fact that bacteria contain several copies of the 16S rRNA gene, which may differ in sequence. The main contribution of this work is design, implementation and evaluation of the capabilities of this tool. Experiments h

Abstract:

The study of microbial communities has deeply changed since it was firstly introduced in the 17th century. In the late 1970s, a breakthrough in the way bacterial communities were studied was brought by the discovery that ribosomal RNA (rRNA) genes could be used as molecular markers to perform organisms classification. Some decades later, the advent of DNA sequencing technology revolutionized the study of microbial communities, permitting a culture-independent view on the overall community contained within a sample. Today, one of the most widely used approaches for microbial communities profili

Abstract:

Background: Enteric methane from rumen methanogens is responsible for 25.9 % of total methane emissions in the United States. Rumen methanogens also contribute to decreased animal feed efficiency. For methane mitigation strategies to be successful, it is important to establish which factors influence the rumen methanogen community and rumen volatile fatty acids (VFA). In the present study, we used next-generation sequencing to determine if dairy breed and/or days in milk (DIM) (high-fiber periparturient versus high-starch postpartum diets) affect the rumen environment and methanogen community

Abstract:

La PCR universelle ciblant le gène codant pour l'ARNr 16S à l'aide d'amorces universelles, a d'abord été développée pour des études phylogénétiques. En effet ce gène est universellement retrouvé chez les bactéries et sa fonction est conservée. Ainsi, il peut servir d'« horloge moléculaire » pour mesurer les distances phylogénétiques entre les différentes espèces bactériennes. La PCR universelle a ensuite été appliquée en microbiologie clinique dans deux domaines distincts : la détection et l'identification bactériennes. Dans ce travail, nous avons évalué l'applicabilité de la PCR « universelle

Abstract:

A produção de etanol nas destilarias brasileiras é baseada na atividade fermentativa da levedura Saccharomyces cerevisiae que utiliza o caldo da cana-de-açúcar e/ou o melaço como substrato. Bactérias contaminantes da fermentação alcoólica competem com as leveduras pelos açúcares, afetando o rendimento do sistema produtivo e, consequentemente, causando perdas econômicas significativas às usinas. Biofilmes formados nos tanques de fermentação alcoólica agem como reservatórios de bactérias, contribuindo para contaminações persistentes e de difícil controle.

Apesar da grande complexidade associada a esses estudos, os fatores que influenciam as comunidades microbianas podem ser melhor elucidados pela pesquisa com grupos específicos. Nesse sentido, o filo bacteriano Verrucomicrobia, grupo ubíquo em solos, apresenta elevada abund

Abstract:

Lactobacillus, a part of the commensal oral microflora, is frequently found in infected root canals but is not considered to be an endodontic pathogen. Lactobacilli have proven to be difficult to identify on species level with biochemical and gene sequencing methods. MALDI-TOF is a new identification method and to our knowledge it has not been used on lactobacilli from infected root canals. The aims of this study were to evaluate the prevalence of lactobacilli in infected root canals and to examine if MALDI-TOF is a suitable method for identifying lactobacilli species.

Abstract:

Bacterial water pollution is a significant problem because it is associated with reduction in the ‘quality’ of water systems with a potential impact on human health. Faecal indicator bacteria (FIB) are usually used to monitor the quality of water, and to indicate the presence of pathogens in water bodies. However, enumeration alone does not enable identification of the precise origin of these pathogens. This study aimed to monitor the quality of bathing water and associated fresh water in and out of the ‘bathing season’ in the UK, and to evaluate the use of microbial source tracking (MST) such
