“…Honey contains several constituents of small amounts, such as minerals, free amino acids, proteins, vitamins, enzymes, organic acids, flavonoids, phenolic acids, and other organic acids in addition to other phytochemicals compounds [ 5 ]. The amount of these components is determined by several factors, including the honey’s geographical origin, floral source, meteorological circumstances, any treatments applied [ 6 ], and seasonality [ 7 ]. Honey’s composition can be affected by processing, handling, and storage [ 8 ].…”

Despite the challenging conditions in the pre-Saharan areas of Algeria, such as weak plant cover and a harsh climate, beekeeping is being developed and spread. In the present work, honey samples collected from ten locations in the El Oued region were examined during the spring of 2021. A melissopalynological analysis was carried out, followed by a floristic investigation. The 10 honey samples were also investigated for their physicochemical properties and antioxidant and antibacterial activity against five strains: Escherichia coli, Staphylococcus aureus, Bacillus subtilus, Listeria innocua, and Micrococcus luteus. The floristic analysis found 65 species belonging to 33 botanical families, with a dominance of the Asteraceae family accounting for 18.461% of the total. The melissopalynological study revealed only one monofloral honey (Ziziphus lotus), whereas the nine others were multi-floral. The honey’s color changed from light to dark amber, and most tested honey was of high quality, fulfilling international criteria. The total phenol and flavonoid contents varied considerably amongst the various honey samples. Furthermore, LC-MS-MS phenolic profile analysis identified the presence of 20 chemicals, of which only three phenols were found in all honey types. Antioxidant capacity analyzed with FRAP test and antiradical activities against DPPH differed from one honey sample to another. Moreover, a significant correlation was recorded between the antioxidant activity, honey’s color, polyphenol, and flavonoid contents. The S. aureus strain was the most sensitive regarding honey antibacterial activity, while M. luteus and B. subtilis strains were only moderately sensitive.

“…According to their responses, the farmers have the poor levels of knowledge on pesticide application and are unaware of the risk of unsafe use of chemical products and their negative impacts. Some Algerian studies had highlighted the possible pesticides' effects on human health, such as perturbations of the reproductive hormones, inflammation, oxidative stress, metabolic perturbations, and prostate cancer [58][59][60], and on the environment, such as the threatening of the existence of bees [61,62].…”

Different pesticides are widely used to protect the crops. However, they are considered to be one of the major causes of environmental pollution. Therefore, in this project, efforts are made to characterize the potential risks of pesticides applied, to study their effects on the environment, and to understand the local professional practices. A survey was conducted among market gardeners and farmers, in two main districts of Biskra Ziban, Algeria. Using pesticide environmental risk indicator model, an Environmental Risk Score (ERS), the final indicator of environmental risk (final indicator of ER), and the normalized final environmental risk were calculated for 18 pesticides, which are most commonly used. Six active ingredients had an ERS that reached a value of 5 and more. The highest final indicator of ER was obtained for the formulation based on the active substance diazinon (score = 120.00). Besides, the perception and attitude of farmers regarding risk from pesticide exposure were also observed and discussed. Consequently, the risk indicators allowed us to compare and identify the least environmentally hazardous pesticide among all the possible alternatives.During cultivation, vegetables and fruits require the use of a broad range of pesticides. Pesticides, when released into the environment, can follow many pathways [6]. Pesticides have a tendency to be sorbed to soil particles [7]; pesticides with high vapor pressures may be easily lost to the atmosphere or move downward into aquifers, whereas soluble pesticides are more leachable to soil and groundwater. Nevertheless, it may be lost as surface water runoff because of irrigation practices or rainfall [7,8]. Pesticides may be degraded and transformed by the biological and chemical processes such as photolysis, hydrolysis, oxidation, and reduction [7,[9][10][11][12].Pesticides benefit the crops, but they negatively impact the environment, particularly, when they move outside of the application site [13,[14][15][16]. Biodiversity is mainly threatened by the intensive use of pesticides [17]. Besides, insecticides or herbicides can be toxic to the hosts of other organisms, birds, aquatic life, beneficial insects, and non-target plants [18,[19][20][21]. Furthermore, pesticides can contaminate soil, water, turf, and

The number of these components contained in honey depends on a variety of factors, such as the geographical origin of honey, the source of the flowers, the weather conditions, and any treatments that were applied [ 15 , 16 ]. Processing, handling, and storing honey can affect its composition in a variety of ways [ 17 , 18 ].…”

Sidr honey is a valuable source of bioactive compounds with promising biological properties. In the present study, antimicrobial, antioxidant, and anti-quorum sensing properties of Saudi Sidr honey were assessed, along with phytochemical analysis, via gas chromatography–mass spectrometry (GC-MS). In silico study was also carried out to study the drug-likeness properties of the identified compounds and to study their affinity with known target proteins assessed using molecular docking approach. The results showed that Saudi Sidr honey exhibited promising antibacterial activity, with MIC values ranging from 50 to 400 mg/mL and MBC values from 50 to >450 mg/mL. Interestingly, the Saudi Sidr honey was active against Candida auris and Candida neoformans, with an MIC value of about 500 mg/mL. Moreover, the Sidr honey showed important antioxidant activities (ABTS assay: IC50 5.41 ± 0.045 mg/mL; DPPH assay: IC50 7.70 ± 0.065 mg/mL) and β-carotene bleaching test results (IC50 ≥ 20 mg/mL). In addition, the Saudi Sidr honey was able to inhibit biofilm formation on glass slides at 1/2 MIC by 77.11% for Bacillus subtilis, 70.88% for Staphylococcus aureus, 61.79% for Escherichia coli, and 56.64% for Pseudomonas aeruginosa. Similarly, violacein production by Chromobacterium violaceum was reduced by about 56.63%, while the production of pyocyanin by P. aeruginosa was decreased to 46.27% at a low concentration of Saudi Sidr honey. ADMET properties showed that five identified compounds, namely, 1-cyclohexylimidazolidin-2-one, 3-Butyl-3-methylcyclohexanone, 4-butyl-3-methoxy-2-cyclo penten-1-one, 2,2,3,3-Tetramethyl cyclopropane carboxylic acid, and 3,5-dihydroxy-2-(3-methylbut-2-en-1-yl showed promising drug-likeness properties. The compound 3,5-dihydroxy-2-(3-methylbut-2-en-1-yl exhibited the highest binding energy against antimicrobial and antioxidant target proteins (1JIJ, 2VAM, 6B8A, 6F86, 2CDU, and 1OG5). Overall, the obtained results highlighted the promising potential of Saudi Sidr honey as a rich source of bioactive compounds that can be used as food preservatives and antimicrobial, antioxidant, and anti-quorum sensing molecules.
