Abstract:

The intestine and associated bacterial microbiota have a central role the physiology and homoeostasis of the host. The understanding of how farming conditions affect the intestine and associated microbiota of fish is the high importance to counteract the potential threats to health and welfare. Thus, this thesis aims to understand the role of stressful husbandry conditions on the intestine and associated microbiota of rainbow trout and Atlantic salmon. Within this context, the role of Pediococcus acidilactici as health promoter was also investigated Chapter 3 investigated the replacement of fi

Abstract:

Probiotics are viable nonpathogenic microbes that positively affect host health. Probiotics inhibit infection, activate immunity, and promote mucosal-barrier development. Many microbes have probiotic activity. Nonetheless, the selection of stable strains and their specific mechanism(s) of action are not fully elucidated. Bacteria from ‘Amabere amaruranu’ cultured milk from Kenya were isolated and identified by PCR sequence analysis of the 16S rRNA gene. Isolates were examined for stability to acid and bile, antimicrobial activity, mucin production, and degradation and sensitivity to antibiotic

Thesis (MSc)--Stellenbosch University, 2013.<br>ENGLISH ABSTRACT: The ocean’s fish resources are declining mainly because of irresponsible exploitation. Fish is a vital source of protein for humans and growing world populations are threatening the sustainability of commercial fisheries. This has led to the rapid growth of aquaculture worldwide. In South Africa, aquaculture of both fresh and marine species is expanding and is now practised in all nine provinces of the country. One of the major problems in aquaculture is the economic losses as a result of diseases. Viruses, bacteria, fungi

In order to meet the increasing demand for food quality and safety, the control of pathogenic microorganisms from farms to consumers remains a continuous challenge.

Abstract:

A significant problem faced by the aquaculture industry is the loss of stock through infection and disease. Cultured animals, particularly larval and post-larval stages, suffer increased incidences of disease primarily as a result of the high population densities at which they aie stocked. Thus far the typical approach to bacterial pathogen control in the majority of commercial crustacean aquaculture facilities involves the prophylactic (and often incorrect) use of antimicrobials, i.e. antibiotics and chemotherapeutic agents.

The use of probiotics administered either in a direct clinical sense or indirectly as a food additive has grown greatly in recent years due to the new 'healthy living' trend. The global market for probiotics was worth R186.2 billion in 2013, showing a growth of 4.3% compounded per annum over a period of five years. Probiotics are however sensitive to different environmental factors such as light, moisture and oxidation in addition to the stresses encountered during processing. The shelf of probiotics in foodstuffs and pharmaceuticals are limited, which lead to increased costs to the manu

Abstract:

碩士<br>國立臺灣海洋大學<br>食品科學系<br>102<br>gamma-Aminobutyric acid (GABA) is a well-known non-protein amino acid, which is widely distributed in animals and plants. GABA has been reported to be a major inhibitory neurotransmitter in the mammalian central nervous system and show antihypertensive activity. This aims of this research are to manufacture a GABA-enriched fermented milk by lactic acid bacteria (LAB) isolated from fish intestines and to evaluate the probiotic potential property of the GABA-producing LAB. Preliminarily, lactic acid bacteria strains were isolated from healthy fish intestine from

Sendo uma atividade económica importante em muitos países contribuiu para o aumento da procura de alimentos de origem aquática. A utilização de bactérias ácido-lácticas (LAB) como probióticos constitui uma alternativa aos antibióticos e à vacinação no controlo das doenças dos peixes de aquicultura, incluindo a lactococose causada por Lactococcus garvieae.

Abstract:

The rise of antibiotic resistance has increased the need for alternative ways of controlling and preventing enteric bacterial infections. Various probiotic bacteria have been used in animals and humans prophylactically and therapeutically. Kefir is an acidic and low alcoholic beverage produced by fermentation of milk, fruit juice, or sugary water with kefir grains and its consumption is associated with prophylactic and therapeutic properties conferred by probiotics components. There is scarce research conducted on kefir and kefir yeast isolates despite claimed potential preventative and

Abstract:

Les diarrhées post-sevrages causées par des infections à Escherichia coli entérotoxinogène positif pour le fimbriae F4 (ETEC F4), entraînent des pertes économiques importantes chez les producteurs de porc. Depuis quelques années, l’utilisation de probiotiques, comme additif alimentaire pour prévenir ce type d’infection entérique et réduire les traitements aux antimicrobiens, suscite un intérêt grandissant en production porcine. Le but du présent travail est de déterminer l’influence de l’administration des probiotiques Pediococcus acidilactici (PA) et Saccharomyces cerevisiae boulardii (SCB) s
