“…The main source of sulphate in soils is through clay content and organic matter addition from plant and animal sources and inorganic fertilizes (Mess and Stoops, 2018 S content just above the critical limit and low in organic matter content(<0.5%), it cannot be considered as sufficient in available sulphur, since there is less organic matter to support to inorganic fraction of S in case of any depletion. In soil sulphur is continuously cycled between inorganic sulphur and organic forms of sulphur (Saha et al, 2018). It is also supported by positive correlation observed between SOC and S.…”

“…Macronutrient sulphur is needed in high amount by plants as it is a constituent of macromolecules like amino acids (cysteine, cystine and methionine) and also involved in regulation of various enzymes like superoxide dismutase, ascorbate peroxidase, monodehydro-ascorbate reductase, dehydro-ascorbate reductase and glutathione reductase. Sulphur deficiency causes chlorosis and low lipid content along with lower plant growth and yield ( Saha et al, 2018 ). Soil is composed of organic as well as inorganic sulphur and the process of conversion of organic sulphur into plant utilizable inorganic sulphur (i.e., SO 4 2− ) form is carried out by sulphur-oxidizing bacteria (SOB) including Xanthobacter, Alcaligenes, Bacillus, Pseudomonas, Thiobacillus sp., Thiobacillus thioparous and T. thioxidans ( Kertesz and Mirleau, 2004 ; Riaz et al, 2020 ).…”

Highlights Agriculture plays an important role in a country's economy. In modern intensive agricultural practices, chemical fertilizers and pesticides are applied on large scale to increase crop production in order to meet the nutritional requirements of the ever-increasing world population. However, rapid urbanization with shrinking agricultural lands, dramatic change in climatic conditions and extensive use of agrochemicals in agricultural practices has been found to cause environmental disturbances and public health hazards affecting food security and sustainability in agriculture. Besides this, agriculture soils are continuously losing their quality and physical properties as well as their chemical (imbalance of nutrients) and biological health due to indiscriminate use of agrochemicals. Plant-associated microbes with their plant growth- promoting traits have enormous potential to solve these challenges and play a crucial role in enhancing plant biomass and crop yield under greenhouse and field conditions. The beneficial mechanisms of plant growth improvement include enhanced availability of nutrients (i.e., N, P, K, Zn and S), phytohormone modulation, biocontrol of phytopathogens and amelioration of biotic and abiotic stresses. This plant-microbe interplay is indispensable for sustainable agriculture and these microbes may perform essential role as an ecological engineer to reduce the use of chemical fertilizers. Various steps involved for production of solid-based or liquid biofertilizer formulation include inoculum preparation, addition of cell protectants such as glycerol, lactose, starch, a good carrier material, proper packaging and best delivery methods. In addition, recent developments of formulation include entrapment/microencapsulation, nano-immobilization of microbial bioinoculants and biofilm-based biofertilizers. Thus, inoculation with beneficial microbes has emerged as an innovative eco-friendly technology to feed global population with available resources. This review critically examines the current state-of-art on use of microbial strains as biofertilizers in different crop systems for sustainable agriculture and in maintaining soil fertility and enhancing crop productivity. It is believed that acquisition of advanced knowledge of plant-PGPR interactions, bioengineering of microbial communities to improve the performance of biofertilizers under field conditions, will help in devising strategies for sustainable, environment-friendly and climate smart agricultural technologies to deliver short and long terms solutions for improving crop productivity to feed the world in a more sustainable manner.

“…Further, the accumulation of proteins, soluble sugars, and chlorophyll was significantly influenced due to seed priming with SOB resulting in higher biomass accumulation. It has been reported that deficiency of sulfur can lead to chlorosis with lower plant growth and yield (Saha et al, 2018). In field studies, inoculation of Thiobacillus and amendment of different levels of sulfur to inter-cropped sesame and mung bean resulted in enhancement of chlorophyll a, chlorophyll b, total chlorophyll, plant growth parameters, and yield (Gilani et al, 2021).…”

The present investigation was carried out to isolate, identify, and characterize sulfur-oxidizing bacteria (SOB) from coal mines and to evaluate the efficient strains for their ability to influence plant growth and S uptake in pigeonpea. Thirteen bacterial isolates belonging to Stenotrophomonas maltophilia (2), Stenotrophomonas pavanii (2), Rhizobium pusense (5), Bacillus velezensis (2), and Paenibacillus massiliensis (2) were obtained. Among these, seven strains that could reduce the pH of thiosulfate broth were further characterized for sulfur oxidation, plant growth-promoting (PGP) attributes, and in planta studies. Among the seven strains characterized, maximum sulfate ion was recorded for S. maltophilia DRC-18-7A (311.43 mg L−1) closely followed by S. pavanii DRC-18-7B (273.44 mg L−1) and S. maltophilia DRC-18-10 (265.75 mg L−1) after 21 days of inoculation. Among the PGP attributes quantified, maximum P solubilization was recorded in case of S. maltophilia DRC-18-7A (24.39 μg ml−1), while highest siderophore production and IAA production were recorded in S. maltophilia DRC-18-10 (14.25%) and R. pusense DRC-18-25 (15.21 μg ml−1), respectively. S. maltophilia DRC-18-7A closely followed by S. pavanii DRC-18-7B outperformed others in enhancing seed germination (%) and vigour indices. Results clearly indicated that microbial inoculants colonized the plant roots and developed biofilm on the root surface. It was further observed that plants treated with microbial inoculants induce an early formation of secondary and tertiary roots in the pigeonpea compared to the untreated control which was further confirmed by assessing the root architecture using the root scanner. Inoculation of these two strains to pigeonpea significantly enhanced plant growth parameters, the activity of reactive oxygen scavenging (ROS) enzymes, and accumulation of flavonoids, carotenoids, and proline both under sterilized and non-sterilized growth medium (sand and soil in 1:3 ratio). The application of microbial inoculants significantly increased the uptake of nitrogen, phosphorus, potassium, and sulfur in plant shoots. Further, transcript level of phosphate, potassium, and sulfur transporter genes significantly increases upon microbial inoculation leading to increased uptake and translocation of P, K, and S in the pigeonpea. The results indicate that S. maltophilia DRC-18-7A and S. pavanii DRC-18-7B could be recommended as inoculants for pigeonpea to improve its growth and sulfur nutrition.
