Total Phenolic Content, Antioxidant and Antimicrobial Properties of Pleurotus ostreatus Grown on Lime (Tilia Tomentesa) Leaves

Abstract

Ö Z E TS unulan bu çalışmanın amacı, atık ıhlamur yapraklarının Pleurotus ostreatus mantarı kültivasyonunda kullanılabilirliğini araştırmaktır. Başarılı bir hasattan sonra, mantarların toplam fenolik madde miktarları, antioksidan ve antimikrobiyal özellikleri belirlenmiştir. Sonuçlara göre, verim %15, biyolojik etkinlik %30, toplam fenol miktarı 1.514±0.001 mg GAE/g, antioksidan aktivitesi 2.508±0.056 μmol FeSO 4 .7H 2 O/g olarak hesaplanmıştır. Ayrıca Pleurotus ostreatus mantarı metanolik özütleri Klebsiella pneumonia ve Acinetobacter haemolyticus bakterilerine karşı inhibitor etki göstermiştir. Sonuç olarak, Tilia tomentosa yaprakları tıbbi özelliklere sahip Pleurotus ostreatus kültivasyonu için uygun bir hammaddedir. Anahtar KelimelerAntimikrobiyal, antioksidan, ıhlamur yaprakları, Pleurotus ostreatus. A B S T R A C TI n this study, the posibility of using of waste lime leaves in Pleurotus ostretatus cultivation was investigated.After a successful harvest, total phenolic content, antioxidant and antimicrobial properties of mushrooms was determined. According to the test results; yield was 15%, biological efficiency was 30%. The total phenolic content was 151.4±0.001 mg GAE/100 g, the antioxidant activity was 2,508±0.056 μmol FeSO 4 .7H 2 O/g. Additionally; methanolic extract of Pleurotus ostreatus mushroom showed inhibitory effect against Klebsiella pneumonia and Acinetobacter haemolyticus bacteria. As a result, Tilia Tomentesa's leaves are suitable raw material with satisfactory medical properties for the Pleurotus ostretaus cultivation.

Investigation of Some Biological Activities of Extracts Centranthus longiflorus subsp. longiflorus

“…This situation is related to the high concentration of phenolic compounds in the above and below-ground methanol extracts. Antioxidant activity occurs due to the natural polyphenolic compounds present in plant extracts [31]. The amount of polyphenolic compounds in plants is important, since plants containing high polyphenolic compounds will be important antioxidant sources.…”

Evaluation of Nutritional and Medicinal Values of Edible Wild and Cultivated Pleurotus ostreatus

“…Woldegiorgis et al (2014) determined total phenolics, total flavonoids, antioxidant activity in DPPH scavenging, reducing power, and chelating effect assays as 14.6 mg GAE/g, 1.97 mg CE/g, 1.4, 3.6 and 0.035 EC50, respectively. Yılmaz et al (2016) reported the total phenolic content as 151.4 mg GAE/100 g and the antioxidant activity as 2508 μmol FeSO4.7H2O/g. In addition, methanolic extracts of P. ostreatus showed inhibitory effect against Klebsiella pneumonia and Acinetobacter haemolyticus bacteria.…”

Antioxidant, Antimicrobial, Cytotoxic, Larvicidal and Anthelmintic Activities and Phenolic Contents of <i>Cyclamen alpinum</i>

“…In tuber part of all extracts was exhibited higher antioxidant activity than in leaf part of all extracts. [37]. The power of eliminating the free radicals of the hydroxyl groups in these compounds is very important [5].…”
