The Evolution of Fungal Diversity,eting degradative enzymes and absorbing nutrients. Because of this absorptive mode of nutrition, the fungi are ubiquitous, intimately associated with their substrates, and able to degrade a diverse range of organic and inorganic materials. The breakdown of substrates, primarily organic materials, by

Algal Diversity and Evolution,ion years ago, life was created by accident. Ancient living cells are presumed to have had RNA as their hereditary element (xcGilbert, 1986). RNA was substituted by DNA and the present form of living cells (possessing protein-synthesizing ability) is the DNA-based organism. DNA organisms evolved to

Evolutionary Relationships of Catabolic Functions in Soil Bacteria,matic pathways discovered in bacteria revealed that essentially all compounds are degraded through a variety of enzymatic steps to limited numbers of common intermediates, such as catechols, which are key compounds for further metabolism. The relationships among the different aromatic pathways and g

Soils are deep but leached of nutrients and, in general, strongly acidic (pH averages 5.0 and aluminum is present at toxic levels, xcVerdade, 1971). Agricultural utilization of the Cerrado was stimulated in the sixties when soil amendments, appropriated technologies, and im

Diversity of Naturally Occurring Prokaryotes,ucture and function, remains a significant challenge for microbiologists. A variety of levels of microbial diversity are important and relevant from the perspective of microbial ecology, including trophic, physiological or functional diversity, intraspecific genetic diversity, or phylogenetic divers
