Rhizosphere Fungi

Endophytic and rhizosphere fungi are understood to be aiding the host plant to overcome a range of biotic and abiotic stresses (nutrition depletion, droughts, etc.) hence, they remain to be reservoirs of plethora of natural products with immense use. Consequently, this investigation of endophytic and rhizosphere fungi isolated from Mikania cordata (a perennial vine that is well established in Sri Lanka) for their antimicrobial properties was performed with the aim of future derivation of potential beneficial pharmaceutical products. Leaves, twigs, and roots of M. cordata were utilized to isolate a total of 9 endophytic fungi out of which the highest amount (44%) accounted was from the twigs. A sample of the immediate layer of soil adhering to the root of M. cordata was utilized to isolate 15 rhizosphere fungi. Fusarium equiseti and Phoma medicaginis were endophytes that were identified based on colony and molecular characteristics. The broad spectrum of antimicrobial activity depicted by F. equiseti (MK517551) was found to be significantly greater (p≤0.05, inhibitory against Bacillus cereus ATCC 11778, Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa ATCC 25853) than P. medicaginis (MK517550) (inhibitory against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, and Pseudomonas aeruginosa ATCC 25853) as assessed using the Kirby-Bauer disk diffusion method. Trichoderma virens and Trichoderma asperellum were rhizospere fungi that exhibited remarkable antimicrobial properties against the test pathogens chosen for the study. T. asperellum indicated significantly greater bioactivity against all four bacterial pathogens and Candida albicans ATCC 10231 under study. The ranges of minimum inhibitory concentrations (MICs) of the fungi depicting antimicrobial properties were determined. The results obtained suggest that F. equiseti, P. medicaginis, T. asperellum, and T. virens of M. cordata harness bioprospective values as natural drug candidates. This is the first report on isolation and evaluation of the antimicrobial properties of endophytic and rhizosphere fungi of Mikania cordata.

Objective. To evaluate the antimicrobial activity of soft and purified propolis extracts. Study object and methods. Antimicrobial activity of soft and purified propolis extracts was determined with reference cultures of Staphylococcus aureus ATCC 25923, Enterococcus faecalis ATCC 29212, Escherichia coli ATCC 25922, Klebsiella pneumoniae ATCC 33499, Pseudomonas aeruginosa ATCC 27853, Proteus mirabilis ATCC 12459, Bacillus subtilis ATCC 6633, Bacillus cereus ATCC 8035, and fungus Candida albicans ATCC 60193. Microbiological tests were performed under aseptic conditions. Minimum inhibitory concentration (MIC) – the highest dilution of preparation (the lowest concentration of preparation) that suppresses growth of reference microorganisms – was determined. Results. Concentration of phenolic compounds in soft propolis extract that possesses antimicrobial activity against gram-positive (Staphylococcus aureus, Enterococcus faecalis) and gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis) is 0.587±0.054 mg and 0.587±0.054–0.394±0.022 mg (P>0.05) and in purified propolis extract – 0.427±0.044 mg and 0.256±0.02 mg (P>0.05). Klebsiella pneumoniae is most resistant to soft propolis extract when the concentration of phenolic compounds is 1.119± 0.152 mg and to purified propolis extract when the concentration of phenolic compounds is 1.013±0.189 mg (P>0.05). Spore-forming Bacillus subtilis bacteria are more sensitive to soft and purified propolis extracts when the concentration of phenolic compounds is 0.134±0.002 mg and 0.075±0.025 mg, respectively, and Bacillus cereus – when the concentration is 0.394±0.022 mg and 0.256±0.02 mg (P>0.05). Sensitivity of fungus Candida albicans to soft and purified propolis extracts is the same as Bacillus subtilis. Encapsulated bacterium Klebsiella pneumoniae is most resistant to antimicrobial action of soft and purified propolis extracts as compared with gram-positive Staphylococcus aureus and Enterococcus faecalis bacteria (P<0.05), gram-negative Escherichia coli, Pseudomonas aeruginosa, and Proteus mirabilis (P<0.05), sporeforming Bacillus subtilis and Bacillus cereus bacteria (P<0.05), and fungus Candida albicans (P<0.05). There is no statistically significant difference between antimicrobial effect of soft propolis extract and purified propolis extract on gram-positive bacteria, gram-negative bacteria, spore-forming bacteria, encapsulated bacteria, and Candida fungus. Conclusions. Soft and purified propolis extracts possess antimicrobial activity. They could be recommended as natural preservatives in the manufacture of pharmaceutical products.

Microorganisms, usually from the dental caries, are the main sources of diseases in dental pulp (root canals) and periapical region. Facultative bacteria and fungi have been identified in therapy resistant persistent endodontic infection. The objectives of this study was to evaluate the antimicrobial efficacy of Mineral Tri Oxide Aggregate (MTA) against therapy resistant endodontic microorganisms. The efficacy of MTA was also compared with that of calcium hydroxide. Six standard bacterial stains were used: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, bacillus subtilis, Candida albicans and Enterococcus faecalis. The agar diffusion method on Muller- Hilton media was employed. The plates containing media were inoculated with the specified bacterial suspensions. Two standard holes were prepared on each microorganism inoculated plate with a copper puncher and one hole was completely filled with MTA & the other with Ca (OH)2 . The plates were then kept at environmental temperature for one hour to ensure prediffusion and then incubated at 370C for 24 hours. After 24 hours, the diameters of inhibition zones were measured. Tests were replicated for thirty times for each sample and mean values were taken. Zone of inhibition as measured for MTA and Ca (OH)2 were statistically analyzed with Student’s t-Test and Post Hoc Games Howell Test and were presented as mean ± SD to compare of efficacy of MTA and calcium hydroxide on different microorganisms. Both MTA and Ca(OH)2 were found to produce zone of inhibition against Staphylococcus aureus (ATCC 25923), Pseudomonas aeruginosa (ATCC 27853), , Bacillus subtilis (BTCC 17 ), and Candida albicans (BTCC 493). MTA showed highest activity against S. aureus and lowest activity against P. aeruginosa which was similar to the activity range of Ca (OH)2 against the mentioned organisms. But both of them failed to produce any activity against E. coli and. E. faecalis. MTA was found to produce a lower efficacy than Ca (OH)2 while comparing the zone of inhibition between them and statistically it was significant. Mineral Tri Oxide Aggregate (MTA) showed antimicrobial efficacy against some therapy resistant microorganisms but it did not show antimicrobial efficacy against Escherichia coli and Enterococcus faecalis. MTA was found to produce a lower antimicrobial efficacy than Ca (OH)2.J Bangladesh Coll Phys Surg 2015; 33(3): 140-145

Present study involves the study of the chemical composition of the essential oils extracted from the leaves by gas chromatography and gas chromatography coupled with mass spectrometry of Lippia multiflora harvested in the regions of Kétou, Savalou, Bohicon and Mono and tested by the well diffusion method against pathogenic microorganisms. The essential oils studied are terpene compounds, aromatic compounds, aliphatic compounds and other natural substances. The inhibition zone diameters determined allowed us to evaluate their degree of germ sensitivity of the strains tested. Essential oils extracted from Lippia multiflora harvested in these areas have the most pronounced antimicrobial activity. In total, the essential oils tested have different and specifically a degree of sensitivity against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Proteus mirabilis A24974, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa except that harvested in the Savalou who does not have no degree of sensitivity on Pseudomonas aeruginosa. This work paves the way for food preservation with extracted natural substances and also the formulation of natural antimicrobials for this fact.

In order to authenticate and ascertain the various claim by the rural dwellers that depend on chewing sticks for their oral hygiene and protection against innumerable diseases, the antibacterial activity of the roots of Fagara zanthoxyloides and Distemonanthus benthamianus were evaluated. Preliminary phytochemical screening was carried out using standard methods. In-vitro antibacterial activity of the methanol extracts of both plants was also carried out using the agar well diffusion method against standard strains of Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Salmonella typhii ATCC 14028, Citrobacter freundii ATCC 8090 and also some clinical isolates of Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae and Proteus mirabilis at different concentrations and ratios. Preliminary phytochemical screening showed that the extracts contained alkaloids, saponin, tannins, steroids, flavonoids, anthraquinones, cardiac glycosides and phenol. All the test microorganisms were susceptible to the inhibitory effect of the extracts at concentrations of 200 mg/ml and 500 mg/ml. F. zanthoxyloides had better antimicrobial activity with zones of inhibition ranging from 21.0 to 26.0 mm at 200 mg/ml and 24.3 to 29.3 mm at 500 mg/ml while D. benthamianus had zones of inhibition ranging from 17.7 to 26.7 mm at 200 mg/mL and 19.0 to 26.7 mm at 500 mg/mL. Some of the test microorganisms were resistant to the standard antibiotics (cefuroxime, ciprofloxacin, ofloxacin and gentamicin). Combinations of the extracts in ratios 50:50 and 75:25 yielded no increase in activity. The MIC and MBC for D. benthamianus ranged from 6.25 mg/ml to 100 mg/mL and 25 to 200 mg/ml, respectively while that of F. zanthoxyloides ranged from 1.56 mg/ml to 12.5 mg/mL and 50 to 200 mg/ml, respectively. The antimicrobial activity demonstrated by F. zanthoxyloides and D. benthamianus indicates that they would be valuable in the management of urinary, respiratory and gastrointestinal tracts infections while at the same time helping to mitigate the problem of antimicrobial resistance. Phenolic compounds of plants, among them flavonoids are the chief constituents, which have potent antioxidant activities Dhaka Univ. J. Pharm. Sci. 18(2): 223-232, 2019 (December)
