“…XL1 produces lysoamidase, from which a drug is derived that is used in the treatment of external infections caused by pathogenic Gram-positive bacteria. It is also effective against many yeast and fungi groups (Ryazanova et al, 2005). Lysobacter enzymogenes was shown to be a potential biocontrol agent for plant fungal pathogens (Folman et al, 2004;Kilic-Ekici & Yuen, 2003).…”

Lysobacter capsici sp. nov., with antimicrobial activity, isolated from the rhizosphere of pepper, and emended description of the genus Lysobacter The taxonomic position of a novel bacterial strain, YC5194 T , with antimicrobial activity, isolated from the rhizosphere of pepper in Jinju, South Korea, was studied using a polyphasic approach. Cells of the strain were Gram-negative, rod-shaped, facultative anaerobes. It grew at a temperature of 15-37 6C (optimum 28 6C). Growth of the strain occurred between pH 5.5 and 8.5, with an optimum of pH 7.0-7.5. The strain inhibited mycelial growth of Pythium ultimum, Colletotrichum gloeosporioides, Fusarium oxysporum, Botrytis cinerea, Rhizoctonia solani and Botryosphaeria dothidea and growth of Bacillus subtilis. The G+C content of the total DNA was 65.4 mol%. The 16S rRNA gene sequence of the strain was most closely related to species of the genus Lysobacter (,94.0 to .99.0 % sequence similarity). Chemotaxonomic data (major quinone, Q-8; major polar lipids, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidyl-N-methylethanolamine; major fatty acids, iso-C 15 : 0 , summed feature 3, C 16 : 0 , iso-C 17 : 1 v9c and

“…To demonstrate the lysozyme activity of each lichen methanolic extract against gram-positive bacteria cells by measuring the absorbance at 660 nm of a suspension of Staphylococcus aureus and Enterococcus faecalis, we have applied the turbidimetrically method (Ryazanova et al, 2005). Brief, bacterial cells obtained from 24h culture at 37 • C, were washed twice with distilled water and then suspended in 50 mM phosphate buffer (pH 6.5).…”

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.

Tetraaqua bismaleato iron(II) [Fe(C 4 H 3 O 4) 2 (H 2 O) 4 ], (1) is a new synthetic antimicrobial agent. Thermal analysis shows that the dehydration of the compound occurs in agreement with the structure. The single crystal salt crystallizes in the triclinic space group P-1 with a = 5.171(2) Å, b = 7.309(3) Å, c = 9.731(3) Å, α = 109.15(2) • , β = 115.02(2) • , γ = 92.42(1) • , V = 313.6(3) Å 3 and Z = 1. Three dimensional network is formed by strong intermolecular O-H. .. O hydrogen bonds. Magnetic susceptibility measurements of 1 in the range 2-300 K exhibited paramagnetic behavior at high temperature. However, at low temperature, the susceptibility data showed weak antiferromagnetic interactions between the local spins. Antimicrobial activity of 1 was tested. It showed high response against gram-positive and gram-negative bacteria as well as fungi and the MIC and IC50 values ranged from 8 to 256 μg.mL −1 and from 1.38 to 22.19 μg.mL −1 , respectively.
