“…These values are within the acceptable microbiological limit ranges in the WHO (World Health Organization) guidelines for evaluating the quality of herbal medicines and the Turkish Food Codex [20,21]. Thyme and olive leaves are known to have antimicrobial effects against many bacteria, viruses, yeasts and fungi [22][23][24]. It can be said that the limited amount of microbial load detected in both plant varieties is due to this.…”

Although COVID-19 disease has lost its former severity in the period from its emergence in 2019 until today, it still maintains its importance. In this study, it is aimed to determine the plants preferred before and during the COVID-19 pandemic and to determine the microbiological quality of these plants. The information form prepared by ourselves was applied to the local herbalists and market employees in Istanbul in order to determine the plants used in the period and before, and to measure their knowledge about the transportation and storage conditions of the plants. It has been determined that the plants whose use has increased compared to before the pandemic process are turmeric (Curcuma longa L.), ginger (Zingiber officinale L.), galangal (Alpinia galanga (L.) Sw.), thyme (Thymus vulgaris L.) and olive (Olea europaea L.) leaves, and they are mostly consumed in the form of tea. Plants were obtained from randomly selected herbalists and markets in open and closed forms, and herb and tea forms were subjected to microbiological analysis using the spread plate method. According to the results of the study, it is important that pathogenic bacteria such as Klebsiella pneumoniae, Bacillus cereus, Escherichia coli, Yersinia spp. were not detected in the herbs and teas. As a result of the analysis, it was determined that the microbial load of the herb and tea forms of the closed samples taken from the markets was higher than that of the open samples taken from the herbalists, and that the microbial load was largely controlled after the brewing process (infusion-decoction). In addition, the importance of maintaining the water temperature in the brewing methods of teas has been demonstrated.

“…Vancomycin, Levofloxacin and Cefepime were used as standard antibacterial agents and Fluconazole was used as the antifungal agent. The results have been interpreted as Highly sensitive (16 mm and larger), Moderately sensitive (11-15 mm), Low sensitive (5.5-10 mm) and Not sensitive (Inactive, <5.5 mm) in terms of the diameter of the inhibition zones (Ilkimen & Gulbandilar 2018). The observed data regarding the antimicrobial properties of all samples and control drugs are given in Table 1 and Table 2.…”

The propolis, which is a natural product that is collected by honey bees from the plants, especially flowers and buds, by mixing it with wax and resin, is used in the hive for many purposes. Apart from the use by the bees in the hive, propolis is a versatile compound that is used in medicine, cosmetics, food industry and apitherapy and which contains a wide variety of chemical substances having antibacterial and antioxidant effects. It was determined that the antimicrobial effects of propolis samples were higher against the Gram-positive bacteria species included in the study when compared to the Gram-negative bacteria and yeasts. The majority of the samples were found to be highly sensitive (16 mm and larger), while some were found to be moderately sensitive (11-15 mm). Among all strains of bacteria; it was demonstrated that the propolis sample obtained from Cankiri (Yaprakli) region performed the highest activity against Staphylococcus aureus while the lowest activity was performed by the propolis sample obtained from Balıkesir region against E. coli. In addition, it was determined that the propolis sample obtained from Eskişehir region had no antifungal effect against Candida parapsilosis yeast strain. It was specified that the antimicrobial activity demonstrated by all microorganisms against the propolis samples was less effective when compared to the control compounds, except for Candida krusei.

“…Six-millimeter diameter holes were then punched carefully using a sterile cork borer and completely filled with the test solutions. The plates were incubated for 24 h at 37 • C. Then, the inhibition zone that appeared around the holes in each plate was measured [43][44][45].…”

The effects of humic acid on plant yield, essential oil content, the composition of essential oil and the antimicrobial activity of Origanum vulgare L. subsp. hirtum (Link.) (cv. Tinmaz) cultivated in 2017 and 2018 under Eskisehir ecological conditions were evaluated. Three humic acid (HA) doses in response to 50.0 L ha−1 (HA 50), 30.0 L ha−1 (HA 30) and 0.0 L ha−1 (HA 0, as control) were applied to soil at the vegetative stage and beginning of the blooming stage of the plant throughout each harvest in both years. Essential oil composition was determined using GC-FID/GC-MS. The antibacterial and antifungal activity were determined by the well-diffusion method. Fresh herb yield, dry herb yield and dry leaf yield were highest at HA 50 both years, although essential oil content increased in 2017 at both HA 50 and HA 30, but was greatest at HA 50 in the second year. The essential oil content differences between the control dose and 50.0 L HA ha−1 were 0.46% and 0.42% in 2017 and 2018, respectively. The antimicrobial activity of the essential oil samples against two bacteria species (Enterococcus faecalis and Staphylococcus aureus and two yeast species (Candida albicans and Candida parapisilosis) was generally higher than that of the control drugs, and the activity increased with increasing HA doses. Analysis of the essential oil components showed that the carvacrol and γ-Terpinene ratios generally increased as the HA doses increased to 50.0 L HA ha−1. Soil HA applications could be recommended for higher quality, plant yield and antimicrobial activity of Origanum vulgare L. subsp. hirtum.
