Factors concerned with the growth & lecithinase production of clostridium welchii type A

1) In the present work, experiments were cerried out for the maximal alphc toxin production. from a strain of Cl. welchii type A grown in a cooked meat medium. The most favourable concentration of each ingr~dient in the mediww alpha toxin production was swere studied. The results showed that when pH was adjusted to 8 pre-autoclaving and to 7 during incubation period high alpha. toxin Was obtainable. 3) Investigations were made to find the incubation period most suitable for maxiillUD alpha toxin productio
