The Dictyostelium purpureum ( Domain: Eukarya; Phylum: Amoebozoa; Class Mycetozoa, Order Dictysliida) belongs to a group of dictyostelids which is known as cellular slime moulds. Their life consists of two stages ― the amoeba and slug phase.
The lab exercises on Dictyostelium purpureum which is plated on different meadia
bearing different “food”. The response of Dictyostelium sp. and the life cycle was observed on
the different nutrient media.
Using aseptic techniques, same amount of fresh, young culture of Dictyostelium purpureum was plated on different media containing the subsequent nutrition: Petri plate (1) Escherichia coli (2) bread (3) potato (4) banana (5) sugar and glucose and (6) water
All observations to be recorded on Table “Number of Fruiting Bodies and Observation of Dictyostelium purpureu”.
