Problem statement: The aim of this study was mainly focused on the evolution of microbial biomasses C and N during the composting of municipal solid wastes. Approach: The carbon and the nitrogen of the microbial biomass (BC and BN) were studied using the fumigation-extraction method. Results: The dynamics of the BC/BN ratio, index of the chemical composition of the whole microbial population su...

Saffron flower (Crocus sativus) is one of the most precious spices in the world. In this respect, thesaffron style samples were gathered from the farms of Torbat-Heidariyeh located in South Khorasanprovince during one year and their preparation was performed based on the common manufacturingstandards. Then, in order to considering the international and national standards for saffron and spicese...

We evaluated the abundance of microbial functional groups involved in compost fertility, and the chemical parameters of maturity and quality most commonly analyzed in compost products. We employed compost produced using the same hydrolytic stage and two maturation processes (with and without earthworms) and with different organic wastes. Our aim was to propose a valid tool for measuring the qua...

Artificial neural networks (ANN) are modelling tools that can be of great utility in studies of microbial water quality. The ability of ANNs to work with complex, inter-related multiparameter databases and provide superior predictive power in non-linear relationships suits their application to microbial water quality studies. To date ANNs have been successfully applied (a) for the prediction of...

This study reviews microbial quality of ready-to eat foods; specifically food safety, basic Hazard Analysis and Critical Point [HACCP] and public perception of food borne diseases. Others include the vulnerable group of food borne diseases, bacterial food borne diseases, causes of food borne diseases. The objective of this study is to review the microbial quality of vended foods in urban school...
