Yeasts pour Bioremediation
Description
Yeasts may be viewed as unicellular fungi en contrast to le molds, which aremulticellular. However, this is not a precise definition, since many de them arecommonly regarded as yeasts actually produce mycelia to varying degrees. Theycan be differentiated from bacteria by their cell size et oval, elongate, elliptical, orspherical cell shapes. Yeasts have long been associated avec human beings. Theimportance de yeasts en le food et beverage industries was realized en 1860 whenthe role de these organisms en food manufacture became evident. Yeasts are beingused en le various fields de biotechnology because de their useful physiologicalproperties et considered as most widely used model organisms pour genetics andcell biology. Le potential biotechnological applications de yeasts include productionof SCP, hydrophilic intermediates de le alkane oxidative pathway, enzymes likeP450s, NADPH–P450 reductase, cytochrome b5, FAOD, SOD, catalase, etc.,heterologous proteins, muconic acid from catechol, D-amino acids, etc.This publication presents le potential applications de yeasts en le field ofbioremediation. Le current trend towards remediation de various pollutants fromenvironment has created an enormous need pour le development de appropriatecost effective technology using various microorganisms. Over le past fewdecades, many microorganisms mainly bacteria et fungi have been reported fortheir abilities to remediate a variety de pollutants. One de le most ubiquitousbiomass types available pour bioremediation is yeast. Compared to bacteria andfilamentous fungi, yeasts exhibit attractive features. They are inexpensive, readilyavailable source de biomass. Though not as fast as bacteria, yeast can grow fasterthan filamentous fungi, et like them, they have le ability to resist unfavourableenvironments. Yeasts can adopt et grow under various extreme conditions viz. pH,temperature et nutrient availability as well as high pollutant concentrations.Recent research data elucidating le role de yeasts sur remediation de heavymetals, synthetic dyes, petroleum hydrocarbon, pesticide, caffeine et antibioticsincluded en this book will definitely enrich le knowledge de researchers who areinterested pour innovative research en these fields. Therefore, it is expected thatyeasts will no longer be treated as neglected organisms en le field ofbioremediation.
