Summary A gasification pilot plant was built up in order to investigate the influence of both feedstock type and co‐gasification on the distribution and composition of the products. The results showed that at the same process condition, different feedstocks could result in different product yields. For instance, the highest gas yield was obtained from tire gasification, while the lowest one belonged to weed gasification. The characterization of the products showed the presence of different components and functionalities in the samples produced. In addition, the co‐gasification of the feedstocks resulted in the products with different specifications than single feeding, proving the existence of different reaction pathways. This means that feedstocks and their derivatives could interact with each other and resulted in nonproportional yields and composition for the char, tar, and gaseous products in comparison with the products from the gasification of the single feedstocks. As an example, the tar from co‐gasification had a lower content of acids but a higher content of amines and amides. This confirmed that co‐gasification influenced the reaction network significantly, impacting the formation of gases, tar, and char, originated from the cross‐interaction among the reaction intermediates derived from the pyrolysis/gasification of the various feedstocks.

Drought is one of the most critical environmental stressors affecting agricultural productivity around the world and it considerably results in yield. Symbiosis interaction between plants and soil microorganisms are considered to enhance plant tolerance in a/biotic conditions. In this study, the impact of Glomus mosseae, Pseudomonas fluorescens strain 169 and both of them under imposed water stress (flowering and pod filling stages) of mung bean (Vigna radiata (L.) Wilczek) was evaluated in two farm experiments during 2016 and 2017. Eco-physiological parameters have been recorded which showed that drought stress reduced the number of leaves, root colonization and seeds yield of mung bean. Mixed inoculation of G.mosseae and P.fluorescens 169 was more effective in alleviation the harm effects of drought stress. Enzymes assay suggested that co-inoculation of G.mosseae and P.fluorescens 169 was more effective to increase antioxidative defense system like catalase (CAT), glutathione peroxidase (GPX) and glutathione reductase (GR) activities. H2O2 contents were increased by water stress both in cutting irrigation at flowering and pod filling stages. In conclusion, plants inoculated with combination of G.mosseae and P.fluorescens 169 had less oxidative damage over control plants.
