Lecture 8 Chapter 7
Microbial Genomes and Chromosomes
Complete DNA sequence of an organism = genome Genome of bacteria is usually circular Can be linear Streptomyces spp. Many bacteria contain plasmids Bacterial genome = 0.69.
Environmental Influences and Control of Microbial Growth
growth conditions are from 20 C to 40C, neutral pH, and 0.9% salt concentration Any organism that can grow outside of that range is considered an extremophile
