phosphate rock production and depletion: regional

phosphate rock production and depletion: regional

Numerous recent studies discuss phosphate rock extraction, and some even propose that a peak in production could be reached in coming decades. This would have great consequences as phosphate rock based fertilizers are irreplaceable in modern agriculture. Studies suggesting an impending peak commonly use curve fitting models where mathematical functions are fitted to historical world production data, while studies using other methods reach completely different results. Also, a sudden increase in global reserve estimates is commonly used to dismiss these warnings, and has somewhat altered the debate. The recent multiplication of estimated reserves is mostly based on an increase of the Moroccan reserve estimate, leading to Morocco currently making up most of the global reserves. This study models global phosphate rock production using a disaggregated curve fitting model based on the production in individual major producing countries, providing a somewhat different view than most studies, and show that the global trade of phosphate rock could be completely dependent on Morocco in the future. There are several different factors that can potentially limit global production and these factors should be considered for the individual producing countries. Society's total dependence on phosphate rock should be further investigated despite claims of large resource occurrences.

Polyphosphate (PolyP), formerly referred to as volutin granules, is ubiquitous with a diverse range of functions. PolyP is present in substantial amounts in prokaryotes and has extensively been researched for various enzymes and pathways involved in its synthesis and degradation. Both the formation and degradation of PolyP are enzyme-mediated processes. Microorganisms utilize PolyP molecules not only as a source of energy and phosphate but also for various other diverse functions including motility, virulence, and gene expression. The present chapter focuses on the biogenesis of PolyP and its application in various fields. The application broadly varies from environmental bioremediation (as heavy metal and enhanced biological phosphate removal) to industrial and biotechnological values (as food additives, detergent additives, and enzyme technology). PolyPs also have applicability in the field of medicine for therapeutic drug design and drug delivery. This chapter later discusses numerous challenges toward the progress of PolyP formation and also the strategies to improve the yield. Metabolic strategies, classical accumulation methods, and lack of biotechnological advancements are considered to be a few of the constraints for PolyP production. To cope with these, many scientists have suggested different ideas such as acidic pH, osmotic stress, nutrient limitation, phosphate and amino acid starvation, presence of organic pollutants, and high-energy state in terms of adenosine triphosphate.
