Soil assessments in organic and conventional systems

Molecular techniques for soil biodiversity studies
• Less than 1% of all bacteria can be cultured.
• Polymerase chain reaction (PCR), denaturing gradient gel electrophoresis (DGGE), quantitative polymerase chain reaction (qPCR) and BIOLOG plates were used to analyse the nifH and total eubacterial community.
DGGE is a method used to examine the diversity of the microbial population that has a certain gene.
qPCR is used to quantify the amount of a certain gene in the population.
BIOLOG Ecoplates show the metabolic fingerprint of the sample.
