This study investigated the use of anaerobic biodigestion as an ecological technique for treating organic waste in urban solid waste. Biogas production is carried out through action microorganisms, and enzymatic hydrolysis can increase biogas production, although it presents economic challenges. The aim was to pre-select microbiological groups enzymes optimize process using statistical tools. O...
The precipitation of struvite from wastewater is a potential alternative for the recovery nutrients, especially phosphorus, which an essential macronutrient agriculture but can be harmful to environment when improperly disposed in water bodies. In addition, has elements great added value agricultural activity (P, N, and Mg) is, therefore, considered sustainable fertilizer. its formation process...
Potassium chloride (KCl) is a highly water soluble substance which is usually used to prevent hypokalemia. Oil in water disperse phase encapsulation method was used to prepare KCl loaded microcapsules using beeswax and carnauba wax as a hydrophobic matrix. The morphology and characteristics of KCl loaded microspheres were studied using scanning electron microscopy (SEM), photon correlation spec...
The aim of this work was to study the pyocyanin pigment from Pseudomonas aeruginosa DN9. involves optimization process parameters for enhanced production under submerged fermentation condition. During process, maximum (92.12 µg/ml) obtained with carbon source mannitole, nitrogen peptone, inorganic salt NaCl and metal ion FeSO4. Plackett Burman design Response Surface Methodology (RSM) showed KH...
Evaluation of twelve medium components on lipase production by Bacillus sphaericus MTCC511 in submerged batch fermentation was studied using the Plackett-Burman statistical experimental design. The most significant variables affecting lipase production were found to be glucose, olive oil, peptone, NaCl and MnSO4 · H2O. Maximum lipase activity of 2.82 U ml–1 was obtained in the batch fermentatio...
