Mutagenicity of Extracts from Composts of Organic Wastes

a study on the design of bio-ethanol process from date wastes of sistan and baluchistan province

اتانول کاربردهای متنوعی در صنایع لاستیک سازی، رنگسازی، حلالها ومکمل سوخت خودرو دارد. اتانول برخلاف نفت از جمله مواد تجدیدپذیر محسوب می شود که مشکلات زیست محیطی و آلودگی نیز ایجاد نمی کند. استفاده از اتانول به عنوان مکمل سوختخودروها از جمله مهمترین مصارف صنعتی این ماده بشمار می رود. با توجه به این موضوع تحقیق و توسعه در زمینه تولید اتانول با درجه خلوص بالا در سطح جهان، و نه تنها در کشور های پیشر...

Organic Fertilizers and Composts

Introduction Interest in organic production methods for vegetables continues to increase. Production practices for organic field production of vegetables have a long history, but practices to grow organic vegetable transplants in a spring greenhouse are poorly known. Organic fertilizers and composts are available but the efficacy and rates for use have not been evaluated. Experiments in the sum...

Evaluation of Mutagenicity Testing of Extracts from Processed Oil Shale

The Ames/Salmonella mutagenicity assay was used to screen processed oil shale extracts for potentially carcinogenic chemicals. Positive mutagenic activity was detected in organic solvent extracts of all four spent shales tested. This result combined with the fact that most carcinogens (90 percent) have been detected as mutagens in the Ames test, indicates that these extracts contain carcinogens...

Biohydrogen Production from Renewable Organic Wastes

Objectives • Investigate different strategies for selective growth of hydrogen-producing bacteria (e.g., heat selection and pH control, hydraulic loading) in a mixed culture environment. • Determine the biokinetics parameters of hydrogen-producing microorganisms. • Identify and quantify hydrogen-producing bacterial population in a complex microbial community background using nucleic acid based ...
