### Microbial Community Analysis of the Manufactured Composts  
The microbial community analysis was compared between the control and the treatments on the laboratory and pilot scales. The integrated samples Tr_2 and Tr_3 were excluded due to their low effectiveness. _Sphingobacteriaceae_uc_ and _B. multivorons_ were highly dominant in both NC and Tr_1. The _B. coagulans_ group, _B. thermoamylovorans_ group, and _O. oleidegradans_ were comparatively higher in Tr_1 with 19% of the distribution. Most of the dominant species were lower in Tr_1 compared to the NC, except the _B. coagulans_ group because of the addition of SB and St-3 cultures (Figure 6a). _Halotalea_uc_ was dominant in both Tr_4 and Tr_5. _P. agglomerans_ and _P. septica_ were dominant in Tr_4, and _C. nuruki_ and _L. acidipiscis_ in Tr_5. _Halotalea_uc_ was the dominant species commonly present in all the samples, covering 40-50% of the distribution in Tr_4 and Tr_5 (Figure 6b). Even though we applied the same ingredients for the laboratory and pilot scales, the distribution of the microbial communities differed. The ratio of the substrates used in the compositing and its processing environment might be the reason for the dominance of different microorganisms.

NC, Tr_2, and Tr_4 were the controls for Tr_1, Tr_3, and Tr_5, respectively; * indicates the significance of the treatment comparing with the control; *—_p_ < 0.05. Analysis of Pepper Growth and Antioxidant Production by Treatment with Functional Composts in Pot Experiments  
To perform the antioxidant tests, the pepper leaves of each treatment were dried, crushed, and extracted using 80% ethanol. The antioxidant properties were examined with three controls of different composts with three treatments including commercial organic and chemical fertilizer (PT-4 and PT-5) (Figure 7). There were generally no significant differences among the composting samples in terms of DPPH and TPC (Figure 7a,b). PT-1 was higher in TFC by 13.1% (Figure 7c), whereas PT-1 and PT-2 were higher in TEAC than their controls (PT-1C and PT-2C) by 36.2% and 32.5%, respectively (Figure 7d).

Inhibition Effect of Streptomycesase SASE St-3 on Plant Pathogens during Radisl Germination in the Presence of Functional Compost Extract  
The treatment with St-3 to the radial seeds infested with the fungal pathogens (_P. ultimum_ and _F. oxysporum_) was compared to the control (infestation of the pathogens without St-3). The radish seedling growth in TPF was significantly higher than its control, CPF, by 12% (Figure 8a). However, the radish germination index in TPP was significantly higher compared to CPP as the control (by 20%) (Figure 8b). Figure 8: Inhibition effects of _Streptomyces sasae_ St-3 on the root rot plant pathogens _Pythium ultimum_ (KACC 40705) (TPP) and _Fusarium oxysporum_ f. sp. _lactuae_ (KACC 42795) (TPF), whose controls were CPP and TPP, respectively; (**a**) Weight per reddish plant, (**b**) Germination index of radish plant; * \(p\) < 0.05 and **_p_ < 0.01.
