applied/industrial Flashcards
what are the positives of biofuels
a good alternative to fossil fuels, is renewable, utilizes agricultural waste
what are the cons to biofuels
take our food and land
what is the main process used in industrial micro
fermentation
what is a primary metabolite
what the organism makes for themself, such as nucleic acids and enzymes
what is a secondary metabolite
what the organism gives off as waste, such as antibiotics
advantages of A. tumefaciens
resident soil microbe, contain Ti plasmid
what are advantages of a Ti plasmid
confer pathogenicity, allow for insertion of genes to genetically modify plants and crops
advantages of B. thuringiensis
microbial insecticide
what is a biotoxin
is not harmful to humans or animals, and does not accumulate in the environment
what are the advantages of the mutualistic relationship between Rhizobium and legumes
bacteria fixes nitrogen for plant
plant gives bacteria nutrients to live
definition of bioremediation
use of microbes to detoxify or degrade a pollutant
three types of bioremediation
natural attenuation, biostimulation, bioaugmentation
what is natural attenuation
reducing amount of xenobiotics in nature
what is biostimulation
addition of nutrients and water to allow processes to occur
what is bioaugmentation
add microbes to degrade a pollutant
what is composting
using bacteria already present to promote degradation
