SPB1 derived biosurfactants (BioS) proved its bio-control activity against using tomato plant. Almost 83% of disease symptoms triggered by were reduced. Aiming potential application, we studied lipopeptide cost-effective production in both fermentations systems, namely the submerged fermentation (SmF) and the solid-state fermentation (SSF) as well as the use of Aleppo pine waste and confectionery effluent as cheap substrates. Optimization studies using Box-Behnken (BB) design followed by the analysis with response surface methodology were applied. When using an effluent/sea water ratio of 1, Aleppo pine waste of 14.08 g/L and an inoculum size of 0.2, a best production yield of 17.16 ± 0.91 mg/g was obtained for the SmF. While for the SSF, the best production yield of 27.59 ± 1.63 mg/g was achieved when the value of Aleppo pine waste, moisture, and inoculum size were, respectively, equal to 25 g, 75%, and 0.2. Hence, this work demonstrated the superiority of SSF over SmF.

The soil microbiome plays an important role in forest functioning. However, the impact of drought-induced dieback and tree death on soil microbial biomass, community structure, and functional composition is unknown. We also lack understanding on how soil microbiota varies seasonally in such declining stands.

Article Synopsis
- The Mediterranean region is highly vulnerable to environmental changes, particularly climate change and air pollution, affecting its unique pine forests.
- This study investigates how the chemical composition of precipitation changes when filtered through Aleppo and black pine canopies on the eastern Adriatic coast, revealing increased ion deposition in the throughfall compared to bulk open field deposits.
- Results show that inorganic nitrogen levels in Aleppo pine forests exceeded critical limits, highlighting the need for ongoing research due to the potential impacts on soil and groundwater health in these sensitive ecosystems.
Chemical Characteristic and Sensory Evaluation of Biscuit Prepared from Wheat and Aleppo Pine Seeds Flour.

This study aimed to explore the potential use of Aleppo pine seed flour as a nutritious ingredient in biscuit production. Aleppo pine seed flour was blended with wheat flour to create biscuits with varying proportions: 15%, 30%, and 45% Aleppo pine seed flour. The analysis of the chemical composition of the biscuits revealed that increasing the proportion of Aleppo pine seed flour led to higher levels of protein, fat, and ash, while the carbohydrate content decreased.

The global scientific community is deeply concerned about the deterioration of water quality resulting from the release of industrial effluents. This issue is of utmost importance as it serves to safeguard the environment and combat water pollution. The objective of this work is to elaborate a biomaterial of vegetable origin, based on the twigs of Aleppo pine, and to use it as an abundant and less expensive material for the treatment of wastewater.
