| Description |
Measurements of the specific activities of the representative enzymes of different pathways linked to
carbohydrate metabolism indicate that glycolysis and TCA cycles are the major route of carbohydrate
catabolism in the sporulating phase of fruiting body development in Pleurotus ostreatus. Enzymes of
the pentose phosphate pathway always showed lower specific activities as compared to those of the
enzymes of the glycolytic pathway. The activity of NADP linked glutamate dehydrogenase which is
known to be an anabolic enzyme decreased drastically in sporulating fruiting bodies and in spore
containing gill tissue (spore bearing structure). Mannitol dehydrogenase activity declined significantly
in the sporulating phase of P. ostreatus.
The high rate of metabolism during sporulation was further supported by a lower rate of gluconeogenesis
at this stage. Concentrations of all the major sugars of the fruiting body (mannitol, glucose and
trehalose) decreased in the mature fruiting body and gill tissue. This indicated high catabolic activities
at this stage of development.
