The most significant issues that humans face today include a growing population, an altering climate, an growing reliance on pesticides, the appearance of novel infectious agents, and an accumulation of industrial waste. The production of agricultural goods has also been subject to a great number of significant shifts, often known as agricultural revolutions, which have been influenced by the progression of civilization, technology, and general human advancement. Sustainable measures that can be applied in agriculture, the environment, medicine, and industry are needed to lessen the harmful effects of the aforementioned problems. Endophytes, which might be bacterial or fungal, could be a successful solution. They protect plants and promote growth by producing phytohormones and by providing biotic and abiotic stress tolerance. Endophytes produce the diverse type of bioactive compounds such as alkaloids, saponins, flavonoids, tannins, terpenoids, quinones, chinones, phenolic acids etc. and are known for various therapeutic advantages such as anticancer, antitumor, antidiabetic, antifungal, antiviral, antimicrobial, antimalarial, antioxidant activity. Proteases, pectinases, amylases, cellulases, xylanases, laccases, lipases, and other types of enzymes that are vital for many different industries can also be produced by endophytes. Due to the presence of all these bioactive compounds in endophytes, they have preferred sources for the green synthesis of nanoparticles. This review aims to comprehend the contributions and uses of endophytes in agriculture, medicinal, industrial sectors and bio-nanotechnology with their mechanism of action.

“…In a study, mung bean seeds (SML668 and SML832) were inoculated with single rhizobium and in combination with rhizobacteria. The combination of rhizobacteria and rhizobium improves mungbean overall growth as compared to their single inoculation with rhizobium ( Kumari et al, 2020 ). A consortium of two PGPR isolates ( Bacillus subtilis and Bacillus pumilus ) was used by the consortium to increase the yield of the bell pepper plant and disease resistance under field conditions ( Kaushal et al, 2019 ).…”

Plant Growth Promoting Rhizobacteria (PGPR) has gained immense importance in the last decade due to its in-depth study and the role of the rhizosphere as an ecological unit in the biosphere. A putative PGPR is considered PGPR only when it may have a positive impact on the plant after inoculation. From the various pieces of literature, it has been found that these bacteria improve the growth of plants and their products through their plant growth-promoting activities. A microbial consortium has a positive effect on plant growth-promoting (PGP) activities evident by the literature. In the natural ecosystem, rhizobacteria interact synergistically and antagonistically with each other in the form of a consortium, but in a natural consortium, there are various oscillating environmental conditions that affect the potential mechanism of the consortium. For the sustainable development of our ecological environment, it is our utmost necessity to maintain the stability of the rhizobacterial consortium in fluctuating environmental conditions. In the last decade, various studies have been conducted to design synthetic rhizobacterial consortium that helps to integrate cross-feeding over microbial strains and reveal their social interactions. In this review, the authors have emphasized covering all the studies on designing synthetic rhizobacterial consortiums, their strategies, mechanism, and their application in the field of environmental ecology and biotechnology.

“…To increase the availability of nitrogen in sustainable agriculture production systems, coinoculation with rhizobia and plant growth-promoting rhizobacteria (PGPR) can be used to enhance symbiotic nitrogen fixation. Several studies, for instance Hungria et al (2013), Sánchez et al (2014), and Kumari et al (2020), have demonstrated that coinoculation of PGPR and rhizobia enhance nodulation, nitrogen fixation, and yield of several legumes, including common bean. Recently, the combined inoculation of plant growth promoting strains to improve the nodulation and nitrogen fixing potential of the inoculated rhizobial strains has received considerable attention.…”

Rhizobacteria are promising as biotechnological methods to improve soil fertility and legume production under field conditions. A field experiment, organized in a randomized complete block design with three replications, was conducted to evaluate the effects of inoculation with plant growth-promoting rhizobacteria (PGPR) in combination with Rhizobium on nodulation, growth, yield components, nutrient and protein content of common bean (Phaseolus vulgaris cv. Nebraska) as a model legume plant. The effect of co-inoculation of Rhizobium and PGPR on soil microbial activity and availability of soil N, P, and Fe was also investigated. Three PGPR strains (Micrococcus agilis KMe7, Serratia marcescens BM1 and Pseudomonas fluorescens TW2) were selected based on their ability to produce indole acetic acid and siderophores as well solubilization of inorganic phosphate. Generally, the results obtained from this study indicated that the co-inoculation of Rhizobium with each of the three tested PGPR significantly increased (P <0.05) the nodulation (nodule number and nodule dry weight), root and shoot dry weight as compared to Rhizobiuminoculated alone and uninoculated control plants at 70 days after sowing. The uptake of N, P, K, and Fe in shoot tissues increased significantly in the co-inoculation treatment and plant growth was enhanced as compared with the single inoculation treatment and uninoculated control. Co-inoculation with Rhizobium and PGPR significantly increased soil dehydrogenase activity compared with single inoculation. Additionally, co-inoculation of Rhizobium and PGPR also had a positive effect on the composition of the rhizosphere microbial populations and significantly increased populations of bacteria, phosphate solubilizing bacteria and siderophores producing bacteria as compared with individual inoculation. The results show that the dual inoculation of PGPR and Rhizobium significantly increased common bean yield and yield components (pods per plant, seeds per pod, and 100-seed weight as well as straw, seed, and biological yields) compared with single inoculation and uninoculated control. Results showed that the best coinoculation treatment was Rhizobium + Pseudomonas fluorescens with relative increase of seed, straw, and biological yield reaching 19.6, 35.4 and 22.2%, respectively, over the Rhizobium alone treatment. Finally, co-inoculation significantly increased the percentage of protein in common bean seeds as compared with single inoculation or uninoculated control. These results indicate that co-inoculation with PGPR and Rhizobium had a positive effect on common bean nodulation, growth, soil nutrients status, nutrients uptake, and yield. The present study concluded that PGPR can be used to promote legume plants in Egypt and to increase soil fertility when it is inoculated with symbiotic N 2 -fixing bacteria.
