Understanding the mechanisms underlying plant biomass recalcitrance at the molecular level can only be achieved by accurate analyses of both the content and structural features of the molecules involved. Current quantification of lignin is, however, majorly based on unspecific gravimetric analysis after sulfuric acid hydrolysis. Hence, our research aimed at specific lignin quantification with c...

Improving water use efficiency and soil properties are two major factors for sustainable development in desert areas. Therefore, this research aims to study the effectiveness of a biological hydrogel, plant vegetation layer, sand and barley straw with rain harvesting techniques through micro-catchment operation on some soil properties including pH, Nitrogen, Electrical conductivity, Sodium Abso...

In semi-arid areas, high climatic variability induce a major risk on food security. Therefore an operational forecasting system for the grain yields is required and could help decisionmakers to make early decisions and plan annual imports. It can be challenging to monitor the crop canopy and production capacity of plants, especially cereals. In this context, the aim of the present study is to a...

Five types of agricultural wastes were used for the production of xylanolytic enzyme by Aspergillus flavus K-03. All wastes materials supported high levels of xylanase and β-xylosidase production. A high level of proteolytic activity was observed in barley and rice bran cultures, while only a weak proteolytic activity was detected in corn cob, barley and rice straw cultures. Maximum production ...

The purpose of this study was to investigate live weight (LW) and body condition (BC) variation in two lines of Rembi sheep reared in extensive and semi-intensive alimentary management. The heavy ewes of the first group were fed with 800g per head/day during winter and spring months. However, the light ewes of the second group received, in winter season, a survival diet regimen consisted of 300...
