“…Results of their study showed that E. cloacae (B1) effectively increased growth characteristics including plant height, fresh weight, dry weight, flag leaf area, and physiological characteristics including chlorophyll pigments content and yield characteristics such as spike length, spikelets number, grains number/spike, 1000 kernels weight, spike weight, biological weight and grains weight, in comparison with control treatment. Opposite to this, the results of Widowati et al [23] showed that the germination percentage and rate of soybeans were not significantly different between controls and Enterobacter cloacea isolate H3 treated samples.…”

This study evaluated the effects of the application of microbial inoculants (N-fixing Klebsiella planticola and Enterobacter spp.), two rates of composite mineral fertilizers, and their combination on microbial biomass carbon (MBC), dehydrogenase (DHA), and proteinase activity (PTA) in Lessivated Cambisol and yield-related properties of maize and wheat grains in a two-year trial. Unfertilized soil was used as a control variant. MBC was measured using the chloroform fumigation-extraction method, DHA was determined spectrophotometrically by measuring the intensity of the formed red-colored triphenyl formazan, while PTA was determined using a titration method by measuring the degree of gelatine decomposition. In grain samples, P was determined spectrophotometrically, K—by flame emission photometry, N—on an elemental carbon/nitrogen/sulfur (CNS) analyzer, and crude proteins—by calculation of N content. Measuring both crops’ yield was carried out at the end of the vegetation. The results indicated that mineral fertilizers are not, in general, negative for soil microbiota when used in the context of sustainable agriculture without monoculture. There is a significant increase in the values of soil MBC, DHA, and PTA in the variants with combined application of bacterial inoculants and lower rates of mineral fertilizers. The highest values of these parameters were determined in the period with a better distribution of precipitation during the vegetation period of the year. The mentioned combination also resulted in a higher grain yield of maize and wheat comparing to the application of lower rates of the NPK nutrients solely. The combined application of high rates of mineral fertilizers and bacterial inoculants resulted in significantly increased N, P, K, and protein content in the grains of crops, and the same applied to yield. Concluding, studied bacterial inoculants can be used to specify the replacement of nitrogen fertilizers, stimulating the microbial biomass and enzyme activity in the soil, helping to ensure that the supply of nutrients contributing to an optimized yield of crops is maintained.

Chemical fertilizer use in agricultural areas causes a variety of issues, including pollution, health risks, disruption of natural ecological nutrient cycles, and the loss of biological communities. In this case, chemical fertilizers, herbicides, and other supplements are replaced by plant growth promoting bacteria for sustainable agriculture. The present research work focus on the isolation of the plant growth promoting bacteria from the Kadi vegetable market waste. Derived from morphological, biochemical, and 16S rRNA gene sequence analysis the strain was identified as Enterobacter cloacae PNE2. The antibiotic susceptibility test indicated that the isolate was sensitive to all 22 antibiotics tested. The isolate Enterobacter cloacae PNE2 has multiple growth-promoting activities like N2 fixation, phosphate, solubilization, potassium solubilization, phytohormone (Indole-3-acetic acid) production, EPS production, biopolymer degradation, and also possesses good seed germination ability. Quantitative analysis of nitrite production revealed the isolate Enterobacter cloacae PNE2 produced 0.15±0.01 µg/ml nitrite. The Phosphate Solubilization Index (PSI) of the isolate was recorded 3.58±0.08 and the isolate released 278.34±0.56 μg/ml phosphate in Pikovskaya’s broth. The isolate Enterobacter cloacae PNE2 solubilized 32.66 mg/l potassium. The isolate Enterobacter cloacae PNE2 possesses IAA (48.49±0.05µg/ml) in presence of tryptophan and EPS (19.1±0.2 g/l) production ability. The isolate Enterobacter cloacae PNE2 was also found to degrade Cellulose, Pectin, and Xylan. Furthermore, the isolate Enterobacter cloacae PNE2 enhances seedling growth of Trigonella foenum graceum (fenugreek). Thus, the isolate Enterobacter cloacae PNE2 has significant plant growth promoting characteristics and can be applied in a bio-fertilizer formulation for sustainable agriculture.
