Bacillus megaterium: Evaluation of Chemical Nature of Metabolites and Their Antioxidant and Agronomics Properties

“…A total of 75 compounds were found to be present in BC extracts and not present in CS2 extracts, as illustrated in Table 3 for analysis without derivatization, and in Table 4 for analysis with derivatization. Some of these identified compounds were strictly found in BC extracts, suggesting a probable production by B. megaterium: 10 fatty acids derivatives (23 ′ , 32 ′ , 34 ′ , 39 ′ , 42 ′ , 44 ′ , 46 ′ , 47 ′ , 36, 44), 5 linear hydrocarbons (4,12,20,24,25), 5 cyclic hydrocarbons with 3 isomers (5,6,8,9,10,11,15,18), 6 amino acids (10 ′ , 12 ′ , 15 ′ , 18 ′ , 20 ′ , 22 ′ ), 2 dipeptides (29, 47), 2 cyclic dipeptides (46, 64), 6 aromatic hydrocarbons (1,16,26,27,31,33), 2 phthalates (59, 61), 2 sugar acids with 1 isomer (9 ′ , 24 ′ , 41 ′ ), 4 polyols with 1 isomer (2 ′ , 4 ′ , 5 ′ , 6 ′ , 21 ′ ), 2 cyclitols (29 ′ , 43 ′ ) and 17 others were identified (3,7,13,14,19,21,23,32,37,43,45,48,50,62, 63, 17 ′ , 38 ′ ). tr indicates integration inferior to 0.1 × 10 6 ; "ND": not detected.…”

“…Thus, natural organisms, especially microorganisms like bacteria, still remain the richest and biggest source for new biocontrol or antimicrobial agents and have emerged as a promising alternative to chemical compounds [5][6][7]. There is a large body of literature reporting the potential use of rhizosphere-associated bacteria with a positive effect on the growth, development or health of plants [8,9].…”
