“…These enzymes are hydrolases involved in the penetration of plant tissue by endophytes. Chitinases are associated with protecting the plant against pathogenic fungi by acting on the fungal cell wall (Castillo et al 2016, Suman et al 2016. Although direct plant growth mechanisms are more important when selecting a microorganism for use as an inoculant, the presence of indirect mechanisms helps the microorganisms to establish in the plant and contribute to plant protection (Hayat et al 2010).…”

“…Many of these mutualistic organisms can act as biofertilizers, increasing the efficiency of nutrient absorption by the plant and producing substances that promote growth. It is estimated that biofertilizers could reduce the use of common fertilizers by 50 % with no yield losses (Pereg & McMillan 2015, Suman et al 2016, in addition to increasing tolerance to abiotic and biotic stresses by promoting biological control (Babalola 2010). In general, microorganisms involved in optimizing plant growth are denominated plant 1.…”

Microorganisms play a vital role in maintaining soil fertility and plant health. They can act as biofertilizers and increase the resistance to biotic and abiotic stress. This study aimed at isolating and characterizing plant growth-promoting bacteria associated with sugarcane, as well as assessing their ability to promote plant growth. Endophytic bacteria from leaf, stem, root and rhizosphere were isolated from the RB 867515 commercial sugarcane variety and screened for indole acetic acid (IAA) production, ability to solubilize phosphate, fix nitrogen and produce hydrogen cyanide (HCN), ammonia and the enzymes pectinase, cellulase and chitinase. A total of 136 bacteria were isolated, with 83 of them presenting some plant growth mechanism: 47 % phosphate solubilizers, 26 % nitrogen fixers and 57 % producing IAA, 0.7 % HCN and chitinase, 45 % ammonia, 30 % cellulose and 8 % pectinase. The seven best isolates were tested for their ability to promote plant growth in maize. The isolates tested for plant growth promotion belong to the Enterobacteriaceae family and the Klebsiella, Enterobacter and Pantoea genera. Five isolates promoted plant growth in greenhouse experiments, showing potential as biofertilizers.

“…The population and abundances of rhizospheric microbes have been affected by several factors such as soil type, soil pH, and other environmental conditions surrounding any plants. A number of microbial species belonging to different genera such as Acinetobacter, Arthrobacter, Aspergillus, Azospirillum, Bacillus, Burkholderia, Enterobacter, Flavobacterium, Haloarcula, Halococcus, Haloferax, Methylobacterium, Paenibacillus, Penicillium, Piriformospora, Pseudomonas, Rhizobium, and Serratia were revealed from the rhizosphere of different crop plants [12,[17][18][19][20][21][22].…”

“…Microbial traits putatively involved in endophytic colonization of plant roots. For penetration, the microbes have to produce cellulolytic enzymes required to hydrolyze the exodermal walls, such as endoglucanases and endopolygalacturonidases [22]. Endophytic microbes exist within the living tissues of most plant species in the form of symbiotic to slightly pathogenic.…”

The beneficial microbes plays an important role in medical, industrial, and agricultural processes. The precious microbes belong to different groups including archaea, bacteria, and fungi which can be sort out from different habitat such as extreme environments (acidic, alkaline, drought, pressure, salinity, and temperatures) and associated with plants (epiphytic, endophytic, and rhizospheric) and human. The beneficial microbes exhibited multifunctional plant growth promoting (PGP) attributes such as N 2 -fixation, solubilization of micronutrients (phosphorus, potassium and zinc), and production of siderophores, antagonistic substances, antibiotic, auxin, and gibberellins. These microbes could be applied as biofertilizers for native as well as crops growing at diverse extreme habitat. Microbes with PGP attributes of N 2 -fixation, P-, and K-solubilization could be used at a place of NPK chemical fertilizers. Agriculturally, important microbes with Fe-and Zn-solubilizing attributes can be used for biofortification of micronutrients in different cereal crops. The biofertilizers are an eco-friendly technology and bioresources for sustainable agriculture and human health. In general, the concentrations of micronutrient in different crops are not adequate for human nutrition in diets. Hence, consumption of such cereal-based diet may result in micronutrient malnutrition and related severe health complications. The biofortification approach is getting much attention to increase the availability of micronutrients, especially Fe and Zn in the major food crops. The beneficial microbes can be used as probiotic as functional foods for human health. Probiotics microbes such as Bifidobacterium, Lactobacillus, Methanobrevibacter, Methanosphaera, and Saccharomyces are increasingly being used as dietary supplements in functional food products. The microbes with beneficial properties could be utilized for sustainable agriculture and human health.
