Abstract: Enzymes are biocatalysts that potentiate the rate of substrate conversion into products. They are composed of amino acids with one or more polypeptide moieties. Microbial enzymes are the various enzymes of microorganisms' source, which have wide scope of applications in medicine and industries, including the degradation of persistent environmental wastes. Persistent environmental pollutants have become a global environmental and health concern. Owing to the rapid technological advancement and development in industries, large quantities of persistent environmental pollutants are being let out into the ecosystem posing serious threats to living organisms, thereby deteriorating the environment. Several microbial enzymes are widely used in the decomposition of recalcitrant organic and inorganic wastes. Oxidoreductases and hydrolases constitute the major class of microbial enzymes utilized in biodegradation of environmental pollutants; oxygenases, laccases, and peroxidases are the superfamilies of the oxidoreductase class, whereas lipases, cellulases, and proteases constitute the superfamilies of hydrolytic enzymes widely employed for bioremediation. Bioremediation involves the use of enzymes of microbial origin or the whole cell in the breakdown or transformation of environmental pollutants into less toxic or nontoxic products. Polymeric compounds such as polyethylene, polypropylene, polystyrene, polyvinyl chloride (PVC), polyurethane (PUR), and polyethylene terephthalate (PET) have been degraded using microbial enzymes. The biodegradation process is, however, often impeded due to the incapability of microbial enzymes to hydrolyze the functional groups present.

I. T.; Yerima, M.B. Abstract: The usage of chemical fertilizers is upsetting the ecology in addition to harming human health. Biofertilizers promote plant development by boosting the delivery of nutrients or compounds that promote plant growth. Growing in popularity in the agriculture sector of developing nations is a novel strategy called nanotech­ nology. Plants exposed to adverse environments respond to nanoparticle stimuli by activating a variety of defense mechanisms. Biofertilizer and nanotechnology were combined to create nanobiofertilizer, which increased agricultural output and efficiency. These fertilizers offer a number of benefits over conventional fertil­ ization techniques and can be utilized to increase agricultural output while mini­ mizing the harmful impacts of fertilizer on the environment. The maintenance of soil moisture and plant uptake of vital nutrients are made easier by the synergis­ tic action of nanomaterial and microbial fertilizer. Additionally, bionanofertiliz­ ers are a low-cost solution to boost soil health, plant nutrient uptake, and growth and production. A new area of research into the production of inorganic and organic bionanoparticles as environmental fertilizers has been launched through the use of bacteria, algae, yeast, fungi, actinomycetes, and plants to biosynthesize nanomaterials. The microbes used as biological fertilizers include Azotobactt:r. Pseudomonas sp, Bacillus sp, and Enteroba.cter sp. In order for these nanobiofertil­ izers to be produced commercially and made available to farmers, it is necessary to research and develop more suitable ones. Nanobiofertilizer is still not widely available for purchase. And the application of proteomics, metabolomjcs and genomics and bioinformatics in nanobiofertilizer research can provide a com­ prehensive understanding of the molecular mechanism underlying plant microbe interaction, nutrient delivery, and crop growth promotion. This knowledge can be exploited to optimize the composition and functionality of nanobiofertilizers, resulting in nutrient use efficiency, improved crop productivity, and environmen­ tal sustainability.

It opens doors for an environmentally friendly sub­ stitutes without altering the ecosystem. The combination of the two methods, nanobiofertilization and bioremediation is a recently developed approach which gives hope for decontamination of the environment and restoring a livable future. It has proven to effectively absorb contaminates in a short period of time and in a friendlier manner. Microorganisms in nanobioremediation play an important role in the removal, detoxifying, degrading, and immobilization of pollutant into less toxic form. Bio- and phytoremediations are exclusively preferred approaches because of the edge it has over numerous methods like high waste cleaning abili­ ties, its cheap, ecofriendly, and generally acceptable. This approach has exception­ ally added to the tolerability and ecorestoration of the environment based on the upper hand it has over other innovations. More so, its efficacy signifies high level of pollutant removal and has lay out new prospect to tackle problem within the environment.
