Abstract

The influence of casing type and raking on the behaviour of bacterial populations during the growth cycle of mushroom (Agaricus bisporus (Lange) Imbach) was studied. After the induction of fructification there was a significant increase in the total bacterial count except for the casing containing composted vine shoots. These high counts were maintained after the second flush in most cases. The count of fluorescent pseudomonads also increased after the casing was added until the induction of fructification and remained high or decreased after the second flush. The results point to a significant (PL0.05) interaction between casing type and raking as regards total bacteria and fluorescent pseudomonads in all three experiments both after the induction of fructification and after the second flush.
