Supplementary Material

Supplementary Figure S1: showed the growth of Natrinema sp. J7-2 on MM plate.

Supplementary Figure S2: showed that in the isolation process of mutants, four strains J7-2-1, J7-2-22, J7-2-26 and J7-2-52 which grow on MGM but failed on MM plate were obtained.

Supplementary Figure S3: the auxotroph of the four auxotrophic strains were reconfirmed with the same experimental procedure that they grow on MGM but failed on MM plate.

Supplementary Figure S4: amplification of important genes in the pathways of the amino acid synthesis from the four auxotrophic strains were shown.

Supplementary Figure S5: showed that the molecular characterization of the gene mutation status of the auxotrophic strains.

Supplementary Figure S6: showed the complementation of the mutation genes by auxotrophic strains’ transformation and comparison the genes of these different transformants.

Supplementary Figure S7: amplification of specific fragments in J7-2-1/ pUC19-HM1752-amyH transformants conferring amylase activity were shown.
