Essential minerals are mostly unavailable in modern cropping systems without the application of synthetic fertilizers, which have a serious negative impact on the ecosystem. This review focuses on the coupling of nanoparticles with biofertilizers to function as nano-biofertilizers (NBFs), which may ensure world food security in the face of the rising population. The inoculation of plants with NBFs improves plant development and resistance to stress. Metallic nanoparticles as well as organic components comprising polysaccharide and chitosan may be encapsulated, utilizing microbe-based green synthesis to make NBFs, which circumvents the limitations of conventional chemical fertilizers. The application of NBFs is just getting started, and shows more promise than other approaches for changing conventional farming into high-tech "smart" farming. This study used bibliographic analysis using Web of Science to find relevant papers on "nano biofertilizers", "plants", and "agriculture". These subjects have received a lot of attention in the literature, as shown by the co-citation patterns of these publications. The novel use of nanotechnology in agriculture is explored in this research work, which makes use of the unique characteristics of nanoscale materials to address urgent concerns including nutrient delivery, crop protection, and sustainable farming methods. This study attempts to fill in some of the gaps in our knowledge by discussing the formulation, fabrication, and characterization of NBFs, as well as elucidating the mechanisms by which NBFs interact with plants and how this benefits the ability of the plant to withstand biotic and abiotic stress brought about by climate change. This review also addresses recent developments and future directions in farming using NBF formulations in the field.

Because of the increase in textile manufacturing, the inhabitants of the area, along with other species, are subjected to the potentially hazardous consequences of wastewater discharge from textile and industrial manufacturing. Different types of dyes emanating from textile wastewater have adverse effects on the aquatic environment. Various methods including physical, chemical, and biological strategies are applied in order to reduce the amount of dye pollution in the environment. The development of economical, ecologically acceptable, and efficient strategies for treating dye-containing wastewater is necessary. It has been shown that microbial communities have significant potential for the remediation of hazardous dyes in an environmentally friendly manner. In order to improve the...

Diarrhoea is one of the major cause for death of young children below the age of 5 years. The aim of the present study was to study bacterial isolates from the diarrhoeal stool samples of pediatric patients and their antibiotic sensitivity assay. A total of 30 patients were screened for the symptoms of disease and sampling was performed. The sampling and isolation resulted in 18 Gram-negative rod shaped isolates and other Gram-positive cocci. The Gram-negative bacteria were subjected to biochemical identification and antibiotic sensitivity assay followed by plasmid DNA isolation and characterization. The isolates were identified biochemically as Escherichia coli. Further, the antibiotic sensitivity assay showed great resistance among the isolates for the commonly used antibiotics against diarrhoeal diseases. The plasmid study showed that the trait of antibiotic resistance is located on the plasmid as the plasmid curing study led to the development of sensitivity of selected isolates towards the antibiotics.

The optimization through one-factor-at-a-time approach revealed maximum growth (A620 1.31) and dye discoloration (95.2%) at optimum temperature 35°C, pH 8.0, inoculum dose 5.0%, sucrose 0.7%, peptone 0.25% and 50 mg reactive orange 4 dye l-1 within 72 h of incubation. Under response surface methodology (using Box-Behnken design) approach, the dye discoloration enhanced to 97.8% at reactive orange 4 concentration of 50 mg l-1, sucrose 0.7% and peptone 0.28% during 72 h of incubation. In bioreactor trial, the maximum dye discoloration (98% within 60 h) was achieved in 12 h advance compared to RSM trial.

Because of the promising relevance of agro-residues in the agri-food-pharma sectors, various bioproducts and novel biologically active molecules are produced through valorization techniques. Valorization of agro-wastes involves physical, chemical, and biological, including green, pretreatment methods. Bioactives and bioproducts development from agro-wastes has been widely researched in recent years. Nanocapsules are now used to increase the efficacy of bioactive molecules in food applications. This review addresses various agri-waste valorization methods, value-added bioproducts, the recovery of bioactive compounds, and their uses. Moreover, it also covers the present status of bioactive microand nanoencapsulation strategies and their applications.

Biological methods for the synthesis of silver nanoparticles are relatively cost effective process. It was aimed at synthesizing silver nanoparticles using water and soil borne bacterial isolates, characterization of silver nanoparticles using UV-Vis spectroscopy and Fourier transform infra red (FTIR) spectroscopy and its effect on multi drug resistant bacterial isolate. The biosynthesis of silver nanoparticles was evaluated in both bacterial biomass and culture supernatant of Bacillus, Pseudomonas and Escherichia coli in the presence of 1mM of AgNO3.On the basis of physical appearances of silver nano particles, Pseudomonas sp. was selected for synthesis. The absorbance spectra of reaction mixture of bacterial biomass and supernatant show the strong peak at 420 nm, indicating the presence of silver nanoparticles (AgNPs) using UV-Vis and FTIR spectrophotometry. The influence of synthesized AgNPs was tested against multi drug resistant (MDR) Staphylococcus sp. on Mueller Hinton agar. The multi antibiotics resistant Staphylococcus sp. showed antibiotic sensitivity against the antibiotic discs impregnated with silver nanoparticles. The characteristics of silver nanoparticles revealed its possible use in biomedical field.

By employing conventional one-factor-at-a-time approach, the bacterial strain exhibited decolorization activity over a wide range of pH (7.0-9.0), temperature (30-38°C), dye concentration (50-200 mg LG 1 MSM) and inoculum size (1.0-6.0%, v/v), with peak activity (68.2% color removal) at pH 8.0, 35°C, 50 mg dye LG 1 MSM and 4.0% (v/v) inoculum in the presence of 1.0% (w/v) glucose as carbon/energy source and 0.2% (w/v) ammonium nitrate within 72 h incubation. Under response surface methodology (RSM using Box-Behnken design) approach, the dye decolorization enhanced to 100% at optimized 40 mg reactive orange LG 1 MSM, glucose 1.0% (w/v) and ammonium nitrate 0.2% (w/v) during 72 h of incubation. The dye decolorization time was advanced by 12 h in bioreactor trial and 100% color removal was achieved within only 60 h incubation. In future experimentation, we envisage to test the potential of our isolate for the decolorization of other variety of azo dyes, mixture of dyes as well as the real textile effluent.

The biosorption of contaminants utilizes a variety of biomaterials. Biosorbents can adsorb toxic pollutants on their surface through various mechanisms like complexation, precipitation, etc. The quantity of sorption sites that are accessible on the surface of the biosorbent affects its effectiveness. Biosorption’s low cost, high efficiency, lack of nutrient requirements, and ability to regenerate the biosorbent are its main advantages over other treatment methods. Optimization of environmental conditions like temperature, pH, nutrient availability, and other factors is a prerequisite to achieving optimal biosorbent performance. Recent strategies include nanomaterials, genetic engineering, and biofilm-based remediation for various types of pollutants. The removal of hazardous dyes and heavy metals from wastewater using biosorbents is a strategy...
