“…Author further reports that the Na uptake in root and shoot tissues were notably reduced over control. Siddikee et al (2011) reported that ethylene concentration increased along with increasing salinity level, ACC deaminase producing halotolerant bacteria inoculation reduced the ethylene production. Soil ions also affected by salinity such as Na and Cl, decreasing water potential, and distributing ion balance concentration; this will negatively impact on nutrient uptake and transportation.…”

“…The bacteria present in the rhizosphere soil have been isolated and tested for their efficiency in plant growth promotion. The use of plant growth promoting rhizobacteria (PGPR) for sustainable agriculture has been wildly used and reported significantly increased plant growth and yield in economically important crops Siddikee et al, 2011;Chabot et al, 1996). Various species of bacteria like Pseudomonas, Azospirillum, Azotobacter, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus, Methylobacterium and Serratia have been reported to enhance the plant growth (Joseph et al, 2007;Kloepper et al, 1989;Poonguzhali et al, 2008) by either direct or indirect mechanisms.…”

Some of the mechanisms had close attention because of their importance in plant growth which includes 1. mineral nutrient solubilization Zahran, 1999) 2. antagonistic activity (Kumar et al, 2012) 3. alleviation of plant stress tolerance to salinity, drought, and metal toxicity (Siddikee et al, 2011;Sandhya et al, 2010) 4. phytohormones production (Merzaeva and Shirokikh, 2010). Ethylene is a plant hormone and it is required for seed germination by many plant species.…”

Microorganisms present in the rhizosphere soil plays a vital role in improving the plant growth and soil fertility. Many kinds of fertilizers including chemical and organic has been approached to improve the productivity. Though some of them showed significant improvement in yield, they failed to maintain the soil properties. Rather they negatively affected soil eventually, the land became unsuitable for agricultural. To overcome these problems, microorganisms have been used as effective alternative. For past few decades, plant growth promoting rhizobacteria (PGPR) and arbuscular mycorrhizal fungi (AMF) have been used as effective inoculants to enhance the plant growth and productivity. PGPR improves the plant growth and helps the plant to withstand biotic and abiotic stresses. AM fungi are known to colonize roots of plants and they increase the plant nutrient uptake. Spore associated bacteria (SAB) are attached to spore wall or hyphae and known to increase the AMF germination and root colonization but their mechanism of interaction is poorly known. Better understanding the interactions among AMF, SAB and PGPR are necessary to enhance the quality of inoculants as a biofertilizers. In this paper, current knowledge about the interactions between fungi and bacteria are reviewed and discussed about AMF spore associated bacteria.

“…The biofilm, which improves soil aggregation and moisture preservation, protects bacterial cells under stress conditions [74]. The EPS can also bond with sodium and decrease its root absorption [75]. However, the specific function and precise role of EPS depends on their structural units and on the environmental characteristics of host microorganisms indicates that further research is needed in this regard [76].…”

A greenhouse experiment was conducted to evaluate the effects regarding inoculation of exopolysaccharide (EPS)-producing bacterium, the extracted EPS and silicon nanoparticles on Solanum lycopersicum L. seeds under salinity stress, in a completely randomized factorial design with three replicates. The inoculated seeds with silicon nanoparticles (8 gr L -1 ), bacterial EPS (0.01 M), and 1 mL of bacterial suspension (1×10 8 CFU mL -1 ) were sown in pots and irrigated with water at different salinity levels (0.3, 2, 4, 6, and 8 dS m -1 ). Results showed that treatment application could enhance salinity tolerance of tomato seeds and improve plant growth so that combined treatments of EPS and silicon nanoparticles (S.E.N), bacteria and silicon nanoparticles (S.B.N), and EPS with silicon nanoparticles and bacteria (S.E.B.N) were the best treatments for plant growth and improvement regarding salinity levels. The mentioned treatments significantly (p<0.01) increased root and shoot fresh or dry weight in comparison to the control sample. In addition, treatments significantly (p<0.01) decreased proline content and antioxidant enzyme activities. Thus, it can be concluded that applied treatments are suitable for agricultural and environmental applications and bring about less damage caused by salinity stress.

The objective of this study was to determine the effect of single and co-inoculation of plant growth promoting bacteria (PGPB) on early plant growth in Saemangeum reclaimed soil. Plant growth promoting Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 were inoculated on maize (Zea mays L.) and sorghum-sudangrass hybrid (Sorghum bicolor L.) grown in Saemangeum reclaimed soil. Single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased plant height, dry biomass accumulation and macro-nutrient accumulation of maize and sorghum-sudangrass hybrid. M. oryzae CBMB20 treatment increased plant height in maize by 41.2% at 30 days after sowing (DAS), shoot dry weight and total dry weight compared to non-inoculated treatment. Macro-nutrient accumulation (N and P) in maize roots was significantly increased with co-inoculation treatment, K and Ca content was significantly increased at B. iodinum RS16 treatment compared to non-inoculated treatment. Macro-nutrient accumulation (P, K, Ca and Mg) in shoot was higher with M. oryzae CBMB20 treatment compared to non-inoculated treatment. In case of sorghum-sudangrass hybrid, co-inoculation treatment showed 33.7% increase in plant height compared to non-inoculated treatment at 30 DAS. M. oryzae CBMB20 treatment increased root dry weight and total dry weight, macro-nutrient accumulation in roots and N, Ca and Mg accumulation in shoot compared to non-inoculated treatment. P and K accumulation in shoot was significantly increased at co-inoculation treatment compared to non-inoculated treatment. This pot culture experiment demonstrated that single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased the early growth and nutrient accumulation of maize and sorghum-sudangrass hybrid.Key words: Brevibacterium iodinum RS16, Maize, Methylobacterium oryzae CBMB20, Saemnangeum reclaimed soil, Sorghum-sudangrass hybrid Effect of co-inoculation of Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 on the early growth of crop plants in Saemangeum reclaimed soil 2
