This study aimed to investigate the impact of methanotrophic and N<sub>2</sub>O-reducing bacterial inoculation on CH<sub>4</sub> and N<sub>2</sub>O emissions, paddy growth and bacterial community structure in paddy field. Two treatments of 100% synthetic fertilizer (250 kg urea/ha) without biofertilizer and 50% synthetic fertilizer (125 kg urea/ha) with biofertilizer consisted of methanotrophic and N<sub>2</sub>O-reducing bacteria were applied in the paddy field. Inoculation of methanotrophic and N<sub>2</sub>O-reducing bacteria was able to reduce CH<sub>4</sub> and N<sub>2</sub>O emission up to 4.19 mg CH<sub>4</sub>/m<sup>2</sup>/day and 351.29 µg N<sub>2</sub>O/m<sup>2</sup>/day, respectively. Those bacterial applications were also able to increase paddy growth and yield productivity. According to DGGE profile, inoculation of the biofertilizer seemed to have a transient impact on bacterial communities in paddy soil at 36 days after transplanting (DAT) which showed the lowest similarity with all samples (a similarity index of 0.68). DGGE bands successfully excised have closest relative to uncultured bacteria which comprised 5 phyla, i.e. Proteobacteria (Alphaproteobacteria and Deltaproteobacteria), Nitrospirae, Actinobacteria, Firmicutes, and Acidobacteria. In this study, Alphaproteobacteria was the most dominant phylum. We provide&nbsp; basic information for developing the biofertilizer which supports sustainable agriculture.</p&gt;}, number={3}, journal={HAYATI Journal of Biosciences}, author={FatmaYuli Siti and RusmanaIman and WahyudiAris Tri and Hamim, Hamim}, year={2020}, month={Jul.}, pages={197} }
