Effects of light source on melanin production. Growth of N. alba MSA 10 on Actinomycetes isolation agar medium (A), Melanin production on tyrosine (1%) agar medium (B), Green light source on melanin production in tyrosine broth (C1) and tyrosine agar medium (C2), which produces dark brown pigment. Red light source produces brown pigment, tyrosine broth (D1) and tyrosine agar (D2). Yellow light shows light brown pigment production on tyrosine broth (E1) at 144 h incubation, but no pigment production in tyrosine agar medium (E2). The pigment production at normal light source on tyrosine broth (F1) and tyrosine agar medium (F2) produces dark brown pigment.
