MICROBES Flashcards
Autolysin
Enzyme in bacillus bacteria which breaks down the beta 1-4 linkage between NAM and NAG during binary fission
Transglycosylase
Enzyme in bacillus bacteria which adds new peptidoglycan units during binary fission
MreB
Protein in bacteria which allows cell elongation by peptidoglycan biosynthesis dictating rod like shape.
Adenovirus
Group of small, naked icosahedral viruses containing linear double-stranded DNA genomes. Cause minor health and respiratory problems.
Haustoria
Specialized structures formed by biotrophic fungal diseases of plants.
Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM)
- involve the direct manipulation of an organism’s genes
Genetically modified organism (GMO)
is an organism whose genetic material has been altered using genetic engineering techniques
Autotrophs
cells/organisms that use inorganic forms of carbon as energy source. Includes most green plants.
Heterotrophs
Cells/organisms that use organic forms of carbon as energy sources. Include many soil organisms.
Organisms found in the soil like root cells, mycorrhizal fungi, and other fungi and bacteria are likely to gain energy from…
organic forms of carbon
Heterotrophs
Autotrophic respiration
CO2 flux that is strongly influenced by recently photosynthesised carbon from plants.
Heterotrophic respiration
CO2 flux that is strongly influenced by decomposition of older carbon such as organic matter
Priming
An increase in degradation of native/ recalcitrant carbon because of inputs of labile carbon
Brown rot fungi
type of wood rotting fungi which excels in degradation of cellulose
white rot fungi
type of wood rotting fungi which excels in degradation of lignin
