L’un des problèmes les plus importants auxquels l’humanité est confrontée est celui du réchauffement climatique. C’est pourquoi les efforts pour trouver des sources d’énergie et de carburant alternatives se sont considérablement accrus. L’une des alternatives les plus efficaces est le biodiesel , qui est une source de carburant neutre en carbone puisqu’il est produit à partir de cultures agricoles. On sait que jusqu’à 20 % de l’huile traitée dans la production de biodiesel aboutit à un déchet, le glycérol brut. Il s’agit d’un déchet de faible valeur car il ne contient que 40 à 60 % de glycérol, le reste étant constitué d’eau, de méthanol, de sels et d’autres impuretés. La purification du glycérol est un processus coûteux. Les microalgues sont des plantes unicellulaires et certaines souches sont capables d’accumuler des quantités importantes de lipides. On sait également que certaines souches de microalgues peuvent épuiser le carbone organique pour satisfaire leurs besoins en nutriments et en énergie. Dans ce livre, l’objectif du travail décrit est d’utiliser le glycérol brut comme source de carbone et d’énergie pour la croissance des microalgues et d’examiner les conditions optimales de croissance en mode chemostat. La biomasse microalgale produite à l’aide de cette technique peut être potentiellement utilisée comme carburant, comme aliment et comme aliment pour animaux.

  • Water from a Transdisciplinary Perspective
    Ana Isabel Pereira Cardoso / Teresinha M. Gonçalves
    Life in cities has distanced human beings from nature and made it difficult to understand the ecology of life dependent on the environment. Urban water collection and distribution processes contribute significantly to the fragmentation of knowledge and the vital recognition of the water cycle. Without the effective participation of the subject in environmental actions, it is no...

  • Modeling Populations of Adaptive Individuals
    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...

    Unlocking the puzzle of how animals behave and how they interact with their environments is impossible without understanding the physiological processes that determine their use of food resources. But long overdue is a user-friendly introduction to the subject that systematically bridges the gap between physiology and ecology. Ecologists--for whom such knowledge can help clarif...
