Abstract:
Ce travail de thèse a été consacrée à l'étude d'un bassin de culture de microalgues (HRAP) avec l'objectif d'examiner les épisodes de mortalité massive, dont la cause est inconnue. Nous avons testé l'hypothèse que des virus de microalgues pourraient être responsables. Cette étude représente la première tentative d'exploration de la diversité virale dans un HRAP, en même temps que la collecte de données des hôtes potentiels grâce au métabarcodage 18S. L’analyse bioinformatique de métagénomes a permis d’identifier des virus présents dans le HRAP, et la dynamique de leurs populations a été suivie

Abstract:
Although, microalgal wastewater treatment systems represent an efficient and economical alternative to conventional processes, the use of marine microalgae to remove nutrients from wastewaters has not been extensively researched and few studies have been made in temperate and high latitude areas, where climate may limit treatment. In this study, 102 marine microalgal species, including 66 local endemic isolates from St Andrews Bay, Fife, Scotland, were screened under batch and continuous culture. Species were selected for their ability to remove high concentrations of ammonium and ortho-phosph

Abstract:
Current abattoir wastewater treatment options involving aerobic and anaerobic digestion systems are relatively inefficient in reducing the inorganic nutrient load (i.e. ammonium and phosphate) of the effluent. With anaerobic lagoons favoured in Australia resulting in large land footprint, loss of environmental and economic value in the form of water and nutrient recovery. The cultivation of microalgae on undiluted anaerobic digestion abattoir effluent (ADAE) offers many potential benefits such as the bioremediation of waste nutrients typically found in the effluent and simultaneous production

Background and Aim: Microalgae are a potential economical source of omega-3 fatty acids, which are known for their health benefits. Omega-3 fatty acids derived from microalgae are however still expensive due to high costs involved in production. These costs can partly be attributed to cultivation of microalgae in unialgal cultures, which are prone to contamination, difficult to scale up and require stringent control of growth conditions. This study therefore is aimed to investigate the feasibility of using a mixed microalgae culture for the production of omega-3 fatty acids. Methods and materi

Abstract:
Due to the large volume of the processed medium in pilot or industrial cultivation systems, it is difficult to illuminate the entire layer of the culture medium, which results in the formation of dark zones. Due to insufficient mixing, also an unbalanced utilization of nutrients contained in the culture medium or formation of temperature gradients can occur. Microalgal biofilm formation attached to the transparent walls of closed photobioreactors (PBRs) is also a significan! limitation associated with scaling-up, since it can significantly reduce the intensity of incident light.

Abstract:
A significant proportion of all waste generated in the world is food waste, contributing up to 8% of global CO2 emissions. Conventional ways of food waste disposal including landfilling and incineration are simply inadequate and unsustainable, emphasizing the need for efficient ways recycling / valorizing food waste. Anaerobic digestion is a way to treat and valorize food waste with significantly less emission of greenhouse gases. However, anaerobic digestion itself produces a waste in the form of anaerobic digestate that is difficult to manage. Microalgae cultivation has been used for the tre

High demands in consumer goods and pressures from governments to meet environmental regulations have pushed industries to find innovative, carbon-neutral solutions. Sustainable methods in biotechnology are sought to increase productivity whilst keeping at bay one of the major problems in monoculture production routes: contamination. The use of engineered consortia is seen as a viable option. In nature, microorganisms exist as part of complicated networks known as consortia. Within the consortia, each member plays a role in facilitating communication, tasks distribution, nutrients acquisition a

Due to a number of factors, the biodiesel industry in the United States is surging in growth. Traditionally, oil seed crops such as soybean are used as the feedstock to create biodiesel. However, the crop production can no longer safely keep up with the demand for the growing biodiesel industry. Using algae as a feedstock has been considered for a number of years, but it has always had limitations. These limitations were mainly due to the production methods used to grow and harvest the algae, rather than the reaction methods of creating the biodiesel, which are the same as when using tradi
