LANGKRAMER O. (1969): Effect of some vitamins on the growth of Suillus variegatus (Sw. ex Fr.) D. Kuntze. Česká Mykologie 23(1): 53-60 (published: 1969)
abstract
The laboratory breeding of pure cultures of Hymenomycetes in synthetic media sometimes does without the addition of growth promoting substances — the vitamins. The paper deals with the effect of vitamins B1, B2, B6, C, para-aminobenzoic acid (PABA), and nicotinamide (NA) on the growth of a pure culture of the fungus Suillus variegatus (Sw. ex Fr.) O. Kuntze. A various degree of the effect of these substances on the growth of the mycelium was noted. Vitamin B1 and PABA showed a slightly inhibitory effect as compared with the control; B2 and B6 promoted growth, while NA had a particularly positive effect.
