Evaluation of indigenous potent mushroom growth promoting bacteria (MGPB) on Agaricus bisporus production
Mushrooms such as Agaricus bisporus, are cultivated for food worldwide. Fruit body initiation in Agaricus bisporus
is a phase change from the vegetative to the reproductive stage which
depends on the presence of a casing layer with particular physical,
chemical and microbiological properties. The phase change is achieved
practically by environmental manipulation and the presence of naturally
occurring bacteria such as Pseuodomonas putida.
In this study, 274 individual bacterial isolates were collected by
screening the casing layer of 14 edible mushroom farms. The isolates
were analysed with respect to biochemical properties, organic and
inorganic phosphate solubilization, production of siderophore and growth
in the presence of volatile compound of 1-octen-3-ol. It was found that
approximately 97% of the strains were able to grow in the presence of
1-octen-3-ol and 36% were able to solubilize phosphorus. Among the
isolates, 23 strains were selected as potent mushroom growth promoting
bacteria (MGPB) for inoculation of the casing layer. Field experiments
using these strains showed various promoting effects on production of
mushroom. Finally, 2 strains (strains Bt4 and Ps7) showing the highest
increase in A. bisporus production, were characterized as Pseuodomonas putida
by molecular methods and identified as the best suited growth promoting
inoculants for application in production farms for increasing the
mushroom yield.
