B. subtilis grew more efficiently in Trichormus extracts (TEs) than in conventional medium (CM) (A: macroscopic observation; B: turbidity analysis). ISS, inorganic salt solution (MgSO4 solution). B. subtilis actively consumed glucose (C) and proteinogenic amino acids (D and E) in the medium and TEs. Downward arrows indicate values below the detection limit. Data are presented as mean ± standard deviation (n= 3). For the statistical analysis of glucose and total amino acid concentrations, comparisons were made between (1) the amounts with and without microbial culture and (2) the amount without microbial culture.
