“…Recently, fear on chemical fungicide which remains in the environment, food and feeds have led to a restriction of some of the agents generally used to control the pathogens of plant and also post-harvest diseases. Several researchers have proposed the biological control [25][26][27] or usage of microbial fungicides 28 can be potential strategy to chemical fun-gicides. Here, we showed that Tabrizica aquatica produces extracellular antifungal compounds which inhibited the growth of Botrytis cinerea, Neurospora crassa and Fusarum oxysparum.…”

Background : Recently, resistant pathogenic microorganisms have become increasingly wide spread. The search for new natural antibiotics is a viable solution to this problem. For this aim we investigated the antimicrobial ability of Tabrizicola aquatica, the novel bacterium isolated from Qurugol Lake located nearby Tabriz city, Iran. Methods: The antimicrobial properties of Tabrizacola aquatica was investigated using well diffusion test. Tabtizicola aquatica was incubated at 40℃ in shaking incubator at 150 rpm for 14 days. The culture was centrifuged to obtain cell free supernatant, which was sterilized using 0.2 μm filter paper and lyophilized. Microorganisms were lawn and then wells were prepared over the agar plates. About 100 ml of the diluted lyophilized supernatant was added to the wells. The plates then were incubated at 37℃. After 48 hours, antimicrobial activity was defined by measuring the inhibition zone diameter. Results: The bacterial filtrates had considerable antagonistic effect against Escherichia coli, Rhizobium radiobacter, Pseudomonas syringae, Erwinia amylovora, Botrytis cinerea, Neurospora crassa and Fusarium oxysporum. However, the filtrates did not show any inhibitory action on the Aspergillus flavus and Klebsiella pneumonia. The supernatant decreased the growth zone on Streptococcus aureus, Pseudomonas aeruginosa, Shigella flexneri, Xanthomonas camoestris and Bassilus cereos. The result of MIC against pathogens was found for Neurospora crassa in the 50 µg/mL. Conclusion: The results, suggested that Tabrizicola aquatica and similar bacteria can be helpful to control freshwater natural water sources from pathogenic microorganism. Moreover, microbial natural products are still the most promising source of new antibiotics. Our results point out a scope for characterization of the metabolites and could be a candidate in the identification of novel antibiotics.

“…Recently, the induction of plant resistance by the application of many microorganisms or organic materials has emerged as a new strategy in the management of plant diseases (Rais et al 2017). Plants are a storehouse of natural compounds that subscribe in suppressing phytopathogens (Sales et al 2016) of which plants supply a worthy source of active natural chemicals such as flavonoids, alkaloids, cucurbitacin, terpenoids, and glycosides (Koul and Walia 2009). Many reports showed that in addition to their suppression of plant pathogens, some natural plant products increased oxidative enzymes in plants that can play an important role in the resistance (Senthilraja et al 2013;Raj et al 2016).…”

Botrytis umbel blight caused by Botrytis allii is a major disease that attacks onion crop. In vitro, Trichoderma viride, Penicillium chrysogenum, and Saccharomyces cerevisiae and extract of bitter apple fruits (Citrullus colocynthis) showed antagonistic effect and inhibited the mycelial growth of B. allii. Gas chromatography-mass spectrometry (GC-MS) analysis of bitter apple fruits showed the existence of 37 compounds and their derivatives. Among them, 10 compounds constituted 58.66% of the total analyses. Greenhouse experiment approved that the extract of bitter apple fruits was the most effective in reducing disease incidence and severity, followed by P. chrysogenum, when they were applied 2 days pre-inoculation with the pathogen. All treatments significantly increased the total phenolic contents than the untreated control, but the highest increase was obtained when S. cerevisiae and P. chrysogenum were applied. A positive correlation was found between the activity of bioagents and improvement of peroxidase and phenylalanine ammonia-lyase enzymes in onion plants to resist infection with the pathogen. P. chrysogenum caused the highest increase in polyphenoloxidase activity in infected onion plants, while S. cerevisiae showed the lowest level of this enzyme. The study approved that application of the bioagents not only protected the onions against Botrytis disease but also enhanced the content of antioxidant compounds in onions. This encourages the application of such preparations to manage the production of onion crop, especially in the organic farming that bans the application of any chemicals.

“…About 6 mm sized, agar wells were created, and 100 µL of LE was introduced. The inhibition zone was measured after incubation at 37°C for 24-48 h. 100 µL of ciclopirox olamine (10 mg/mL) (synthetic antifungal agent), SDB, and dimethyl sulfoxide (DMSO) was used as positive, negative, and vehicle control, respectively [18].…”

Objective: The present study assessed the antioxidant activity, phytochemical content, and anti-Candida albicans property of ethanolic extract of Glycyrrhiza glabra L. (licorice). In addition, suppository formula (SF) was developed with licorice extract (LE), and the stability of SF was evaluated.Methods: The total phenolic and flavonoid content was measured by colorimetric methods. 2, 2′-azino-bis-3-ethylbenzthiazoline-6-sulfonic acid (ABTS), ferric reducing antioxidant power (FRAP), inhibition of lipid peroxidation (LPO), nitric oxide (NO), and superoxide (SO) radical scavenging assays were performed to evaluate antioxidant property. Antimicrobial activity was determined by plating method. The active principle was determined by high-performance liquid chromatography method.Results: The licorice sample was extracted with 95% ethanol, and 26.91±1.35% of yield was observed. The LE contains phenolic acids (167.70±3.18 mg gallic acid equivalent/g extract), flavonoids (162.53±9.95 mg quercetin equivalent/g extract), and glabridin (3.90±0.05 mg/g extract). LE exhibited the scavenging activity in terms of 810.53±25.37 μM of Trolox equivalent/mg of extract, 165.04±5.10 μM of FeSO4 equivalent/mg of extract, and 3750.35±1.25, 68.25±0.07, and 511±0.80 μM of Trolox equivalent/mg of extract in ABTS, FRAP, LPO, NO, and SO assays, respectively. About ≥62.50, ≥125, and ≥250 μg/mL of LE was recorded as minimal inhibitory concentration against C. albicans, Lactobacillus casei, and Lactobacillus acidophilus, respectively. The SF was formulated and the stability was evaluated. The activity and color of SFs did not differ on storage. Moreover, no spot formation was observed.Conclusion: The SF with LE could be the safe therapeutic strategy for the treatment of candida infection in vaginal region.
