The invention belongs to the technical field of
biology, and particularly relates to a method for improving acid-eating bacterium tolerance and degrading high-concentration
pyridine. According to the specific technical scheme, the method for improving the tolerance and
pyridine degradation capacity of the
acidovorax sp. Comprises the following steps: extracting a
corncob medullary layer leaching solution, and adding the
corncob medullary layer leaching solution into a growth environment of the
acidovorax sp. According to the invention, it is found for the first time that the
corncob medullary layer
leachate can effectively improve the tolerance and high-concentration
pyridine degradation capability of
acidovorax. By adding the corncob medullary layer
leachate in the
culture environment of the acidovorax
bacteria, the acidovorax
bacteria can degrade 99% or more of about 2700 mg / L of pyridine after being treated for about 84 hours. The method provided by the invention can effectively improve the high-concentration pyridine degradation effect of the acidovorax LD-B, the method is simple, and the used corncob is an
agricultural waste, is wide in source and low in price, has both environmental friendliness and
sustainability, greatly reduces the application cost, and has huge popularization value.
