Microbial degradation of poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) in soils.

abstract：:The nonlinear thermal inactivation of Aspergillus niger spores in phosphate-citrate buffer was studied. The thermal inactivation pattern of the spore consisted of a shoulder, an accelerated decline, and a tail at various constant temperatures around 60 degrees C. The pattern fitted a thermotolerant subpopulation model...
