“…In the coordination chemistry of transition metals such as vanadium, much attention has been devoted to oxalate-containing (C 2 O 4 2or ox 2 ) complexes due to their interesting structural, catalytic [13,14] and magnetic features. [15,16]. The bioinorganic relevance of vanadiumoxalate chemistry, in its turn, has been addressed in a variety of levels [16][17][18].…”

“…[15,16]. The bioinorganic relevance of vanadiumoxalate chemistry, in its turn, has been addressed in a variety of levels [16][17][18]. Under physiological conditions, vanadium(IV) has a high affinity for O-donor bioligands as lactate, citrate and oxalate, which prevents hydrolysis and precipitation of insoluble VO(OH) 2 [19].…”

“…Minimal bactericidal concentration (MBC) was determined from the microdilution plates used in the MIC assay, according to [ 65 ] with modifications [ 66 ]. Aliquots (10 μ L) of each well without visible growth were transferred to TSA plates, incubated at 36°C for 24 h, and colony growth was verified as previously reported [ 67 ].…”

“…The mixed reaction was containing 0.1 mL of diluted oil (1/4) and 0.1 mL of suspension bacterial cell prepared in phosphate buffer after incubation for 60 min at 37°C. The activity was tested turbidimetrically by measuring the decrease in absorbance at 660 nm of the bacterial strain suspensions [ 66 , 67 ]. Data were the average of three replications and were expressed in arbitrary units per mL (AU/mL).…”

Infection of skin injuries by pathogenic microbial strains is generally associated if not treated with a lasting wound bed oxidative stress status, a delay in healing process, and even wound chronicity with several human health complications. The aim of the current study was to explore the antioxidant and antimicrobial potentialities of safflower (Carthamus tinctorius L.) extracted oil from seeds by cold pressing which would be beneficial in the management of skin wounds. Antioxidant capacity of the oil was evaluated (scavenging ability against 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) and 2,2 ′ -azino-bis 3-ethylbenzothiazoline-6-sulfonic acid (ABTS), and ferric reducing antioxidant power (FRAP)). Total phenolic, total flavonoid, total carotenoid, and total chlorophyll contents were determined. Antimicrobial activities of safflower oil were tested against 10 skin pathogenic microorganisms: 4 bacterial strains (Escherichia coli, Enterobacter cloacae, Staphylococcus aureus, and Streptococcus agalactiae), 3 yeast species strains (Candida albicans, Candida parapsilosis, and Candida sake), and 3 fungi species (Aspergillus niger, Penicillium digitatum, and Fusarium oxysporum). A notable antioxidant capacity was demonstrated for the tested oil that exhibited moreover high antibacterial effects by both bacteriostatic and bactericidal pathways including lysozyme activity. An antifungal effect was further observed on the spore’s germination. Safflower oil could be considered as a good natural alternative remedy in the management of skin wounds and their possible microbial infections.

“…The mix reaction consisting of 100 µL of the bacterial cell wall suspension and 50 µL of the tested extracts adjusted at 2000 µg/mL and incubated at 37 • C for 60 min. Arbitrary Unit of lysozyme activity was determined as the decrease in OD at 660nm with 0.001per mL of the extract solution per min compared to the untreated one (Sehimi et al, 2019).…”

This study compared the efficacy of two species of lichen located in Tunisia belonging to Cladonia rangiformis and Cladonia pocillum species. The antibacterial and antifungal potentials of methanol, acetone and quencher extracts of C. rangiformis and C. pocillum and the lysozyme activity of both methanol extracts were investigated. The results showed that the examined extracts had antimicrobial properties against gram-positive and gram-negative bacteria and anti-Candida properties and that they also limited the spore germination of Penicillium and Aspergillus. Further results showed that the largest diameter of the inhibition zone was obtained by the methanolic extract of C. pocillum with 31 mm and 27.5 mm against E. cloacae and E. coli, respectively. MIC values of bactericidal and fungicidal activities of both Cladonia extracts ranged from 0.25 mg/mL to 2 mg/mL. C. pocillum possess superior lysozyme activity against Staphylococcus aureus and Enterococcus faecalis. Furthermore, the methanol extract of both Cladonia showed a remarkable destructive effect on the morphology of fungal hyphae.
