Paenibacillus sp. S1S22 Suşu ile Ulva lactuca Ekstresinin Kombine Kullanımının Domates Bitkisinin Büyümesi Üzerine Etkilerinin Belirlenmesi

In recent years, plant growth promoting bacteria (PGPB) have been used as biofertilizers that increase agricultural productivity and resistance to changing environmental conditions such drought, salinity heat stress. One of the proposed new approaches productivity, especially under stress conditions, is using algae extracts, which usually consist naturally occurring bioactive compounds. Paenibacillus sp. S1S22 isolated from sediment was tested for its performance in indole acetic acid production (IAA), nitrogen (N) fixation, phosphate solubilization, proteolytic activity, cellulose activity. Its antimicrobial activity also determined against different pathogens S1S22. Tomato seeds were incubated with strain, strain supplemented U. lactuca. The deionized water control. As a result, we demonstrated addition lactuca extract tomato seedlings increased root stem length compared results indicate macroalgae combination PGPR may be much more effective way growth.
