Genetic Engineering and Biotechnology Genetic engineering: Isolation manipulation and expression of genetic materials. Gene cloning: Isolation and purification of specific genes In vitro recombination=recombinant DNA

Microbial Ecology: Microorganisms in soil, water, and other environments and how microorganisms act to chemically change their environments. Microbial ecologists study: the biodiversity of microorganisms in nature and how different guilds interact in microbial communities The activities of microorganisms in nature and monitor their effects on ecosystems

Population, environment and development For example World population has more than doubled in only 43 years, from 2.5 billion in 1950 to 5.5 billion in 1993. Unless death rates rise sharply, it may reach 11 billion by 2045, and 14 billion by 2100 Resources, economic development, and resource scarcity All countries seek economic growth: increasing their capacity to provide goods and services for final

Fairly primitive and predictive power limited Function Points Count number of inputs and output, user interactions, external interfaces files used Assess each for complexity and multiply by a weighting factor Used to predict size or cost and to assess project productivity

Lecture 7 Tourism and Sustainable Development Tourism is the world's largest industry(WTTC et al., 1995). It employs approximately one in nine workers worldwide, comprising 6% of global gross national product (GNP) and, it has been seen as a panacea for solving many social problems and for driving economic growth

Methods in Microbial Ecology Microbial ecology focus on two major issues: (1) biodiversity, including the isolation, identification, and quantification of microorganisms in various habitats, and (2) microbial activity, that is, what are microorganisms doing in their habitats. We begin here with a consideration of assessing biodiversity through enrichment and isolation, and then consider nonculture methods of identification
