The aim of this study was to compare the effects of four fertilizer applications-control (C), chemical fertilizer (F), compost (O), and in situ earthworm breeding (E)-on the growth, quality and yield of papaya (Carica papaya L.). In this study, 5 g plant-1 urea (CH4N2O, %N = 46.3%) and 100 g plant-1 microelement fertilizer was applied to each treatment. The fertilizer applications of these four...

A search for alternatives economically viable and environmentally sound to the world energy demand, stimulated research in field of anaerobic digestion, as a form renewable co-digestion is an alternative use different types residues, including food wastes. Therefore, this article presents analysis scientific advances realized period 2015 2018 terms co-digestion, with emphasis on especially frui...

Single-cell protein (SCP) from agro-waste material has gained increased attention in the recent past as a relatively cheap and alternative source to meet nutritional demand generated by fast-growing population. Furthermore, bioconversion of these wastes into SCP such value-added products reduce environmental-related issues. In this study, locally available pineapple (Ananas comosus), watermelon...

For clean a agriculture and safe environment, this study was conducted, which included the preparation of compost from Prosopis fracta Alhagi maurorum plants, evaluation Its as medium for tomato seedlings production comparing it with peat moss, an organic fertilizer in comparison number fertilizers - poultry wastes, cow sheep wastes spent mushroom residues, results showed superiority prepared o...

Organic wastes such as sewage sludge have been successfully used to increase crop productivity of horticultural soils. Nevertheless, considerations of the impact of sludges on vegetable and fruit quality have received little attention. Therefore, the objective of the present work was to investigate the impact of two sanitized sewage sludges, autothermal thermophilic aerobic digestion (ATAD) and...

Background: Enzyme production by solid state bioprocess (SSB) using residues as substrate for microorganisms is an alternative for costs reduction and to avoid their disposal into environment. The aim of this work was to evaluate the physiology of the fungus Lichtheimia ramosa in terms of microbial growth and production of amylases, β-glucosidases, carboxymethylcellulase (CMCase), and xylanases...

Fermentable components of municipal solid wastes (MSW) such as fruit and vegetable wastes (FVW), leaf litter, paddy straw, cane bagasse, cane trash and paper are generated in large quantities at various pockets of the city. These form potential feedstocks for decentralized biogas plants to be operated in the vicinity. We characterized the fermentation potential of six of the above MSW fractions...
