The objective of this study was to investigate the antibacterial activity of primary and secondary metabolites from Vibrio alginoliticus isolated from sponge Haliclona sp. against Staphylococcus aureus. A descriptive method was used in this research. The antibacterial activity was analysed by paper disk method. The results showed that the primary metabolites produced by Vibrio alginoliticus tha...
Protein translocation is essential for bacterial survival and the most important translocation mechanism in bacteria is the secretion (Sec) pathway. Thus targeting Sec pathway is a promising strategy for developing novel antibacterial therapeutics. We report the design, syntheses, mechanistic studies and structure-activity relationship analyses using HQSAR and 3-D QSAR Topomer CoMFA analyses of...
Sapecin B, an antibacterial protein of Sarcophaga peregrina, was divided into four peptides. A hendecapeptide derived from its helix region was found to have comparable antibacterial activity with that of the complete protein. This peptide had a much wider spectrum of antimicrobial activity than that of sapecin B, exhibiting activity on not only Staphylococcus aureus (Gram-positive) and Escheri...
The antibacterial activity and mechanism of berberine against Streptococcus agalactiae were investigated in this study by analyzing the growth, morphology and protein of the S. agalactiae cells treated with berberine. The antibacterial susceptibility test result indicated minimum inhibition concentration (MIC) of berberine against Streptococcus agalactiae was 78 μg/mL and the time-kill curves s...
A suspension tobacco (Nicotiana tabacum L.) cell line was transformed to express human lactoferrin, an iron-binding glycoprotein. The transgenic calli produced a protein that was significantly smaller than the full-length lactoferrin protein. Total protein extracts made from transgenic tobacco callus exhibited much higher antibacterial activity than commercially available purified lactoferrin a...
The main objective of this research is to investigate the anti-biofilm and anti-bacterial activity of Sesbania grandiflora (S. grandiflora) against Staphylococcus aureus. S. grandiflora extract were prepared and analyzed with UV -Vis spectroscopy, Fourier transform infrared spectroscopy, Dynamic light scattering. Biofilm forming pathogens were identified by congo-red assay. Quantification of Ex...
The present study demonstrates an economical and environmental affable approach for the synthesis of "protein-capped" silver nanoparticles in aqueous solvent system. A variety of standard techniques viz. UV-visible spectroscopy, transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) measurements were employed to characterize the shape, size and ...
The protein extract of Etroplus suratensis (E. suratensis) collected from Bavanisagar dam was found to be effective against all tested organisms with an inhibition zone ranging from 0.2 to 1.9 mm. When the result was compared with standard antibiotic Streptomycin, a moderate efficiency was observed. In vitro, an antibacterial assay was used to assess the efficacy of fish protein in inhibiting t...
با توجه به شیوع سرطان در جوامع امروزی، یافتن داروهای جدید برای درمان آن از اهمیت بالایی برخوردار است. استفاده از داروهای شیمیایی موجود به دلیل عوارض جانبی که دارند با محدودیت مصرف روبه رو می باشند. از این رو محققین درصدد یافتن مواد طبیعی با خاصیت ضد سرطانی می باشند. هدف اصلی این پایان نامه بررسی اثرات ضد سرطانی lactoferrin وwhey acidic protein موجود در شیر شتر می باشد. در تحقیق حاضر تأثیر lacto...
