Abstract

Jamur shiitake (Lentinula edodes (Berk.) Pegler) merupakan salah satu jamur yang berpotensi sebagai jamur pangan dan bahan obat (edible and medicinal mushroom). Kultivasi pada medium cair dengan proses fermentasi telah dikembangkan selama beberapa tahun terakhir ini. Empat isolat L. edodes (isolat asal Malang, Cianjur, Lembang dan Yogyakarta) dikultur pada tiga jenis medium fermentasi yaitu (KM: Kauffman Medium; GYMT: Glucose, Yeast extract,  Malt extract, Thiamin; YEMR: Yeast extract,  Malt extract,  Rice bran). Metabolit bioaktif yang diekstrak dari biomassa miselium dan filtrat kultur hasil fermentasi diuji menggunakan mikroba patogen Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 35218, Candida albicans ATCC 10231,dan  Trichophyton mentagrophytes. Data diameter zona  hambat dianalisis menggunakan analisis ragam, dan dilanjutkan dengan uji Duncan pada tingkat kesalahan 5 %. Hasil penelitian menunjukkan bahwa senyawa bioaktif dalam filtrat kultur maupun biomassa miselium L.edodes yang diekstrak menggunakan kloroform, etil asetat dan air, mampu menghambat S. aureus, E.coli dan C. albicans tetapi tidak mampu menghambat T.mentagrophytes. Isolat L.edodes asal Lembang dan Yogyakarta yang dikultur pada medium Kauffman memberikan hasil zona hambat terbaik (24,97-31,14 mm). Mikroba uji yang paling sensitif terhadap senyawa bioaktif dari L. edodes adalah C. albicans diikuti oleh E.coli, S. aureus dan T. mentagrophytes. Metabolit bioaktif dari L. edodes berpotensi menghambat mikroba patogen dari kelompok bakteri dan khamir tetapi tidak menghambat jamur.

Abstract

Phenetic relationship of shiitake mushroom (Lentinula edodes (Berk.) Pegler) cultivated in Indonesia especially in Java is still undisclosed. In order to increase adaptability and high production most of cultivators in Indonesia make inter-isolates breeding. Consequently  L. edodes isolates grown in Indonesia may have morphological and genetic diversity. Diversity among the isolates of L.edodes can be determined by morphological and molecular assessments. Isolates originating from different locations can show specific morphological characters, and requires more in-depth assessment of the macroscopic and microscopic morphological characters. Four  L.edodes isolates from Malang, Cianjur, Lembang and Yogyakarta were understudy to determine their morphological characters and phenetic relationship. Degree of similarity between the isolates was carried out through numerical taxonomy approach and the data obtained were analyzed using the Numerical taxonomy program and multivariate analysis system, version 2.1. The results showed that there was diversity of morphology of the four isolates and based on the results of data analysis obtained, the degree of similarity between the isolates ranged between 83-95%. Isolates of L. edodes from Malang to Cianjur showed the closest phenetic relationship (95%) and isolates from Malang to Yogyakarta showed the most distant phenetic relationship (83%). Based on the morphological characters obtained from this research revealed the diversity and phenetic relationship among the four isolates of L. edodes.

Abstract

Pleurotus ostreatus cultivation is performed using solid medium to harvest fruit body and using liquid medium to harvest mycelia in submerged culture. Modifying nutrients in the medium to increase protein content of the fruitbody and mycelia can be done through addition of nitrogen-containing materials. This study aims to determine: the appropriate composition of the liquid medium for high mycelial growth and protein content; and the exact composition of the solid medium to obtain high fruitbody product and protein content. The method was experimental with completely randomized design (CRD). The treatments were incubation of P. ostreatus on three types of liquid medium and four types of solid medium. The results showed that the optimal liquid medium composition for mycelial growth was Liquid Fermentation Medium 1 (FC1) with 10% corn fluor, and the highest protein content was in Liquid Fermentation Medium 2 (FC2 = 29.76%). While the optimal solid medium composition for fruitbody production was the medium with 3% corn starch supplement (TJ3), and the highest protein content was obtained from the medium without corn starch supplement (TJ0=24.69%). The increase of mycelial and fruitbody weight from the medium with the addition of corn material indicated a prospective in cultivation process, however effort to increase protein content of the fruit body needs further research. Cultivating P. ostreatus in mycelial phase may take shorter incubation time, may be produced in mass production with less space consuming, and higher protein content than that by producing fruitbody.

Abstract

Button mushrooms (Agaricus bisporus) is an edible mushroom that is most widely cultivated in the world. It contains bioactive compounds that might provide beneficial effects on diabetes mellitus patient. The study aimed to determine the effects of A. bisporus administration on the blood glucose, and malondyaldehyd (MDA) levels as well as superoxide dismutase (SOD) activity of alloxan-induced diabetic rats. This study was also conducted to determine the secondary metabolites produced by A. bisporus. The method used was experimental methods with Completely Randomized Design. A. bisporus extract at the doses of 250, 500 and 750 mg/kg body weight (BW) per day were orally applied to alloxan-induced diabetic rats for a period of 14 days after the rats became diabetes. The results showed that the extract of A. bisporus could decrease blood glucose, and MDA levels as well as increase SOD activity (p < 0.05). A. bisporus extract 500 mg/kg BW is the most effective dose to be used. Based on Thin Layer Chromatography (TLC) test, it was known that secondary metabolites produced by A. bisporus are flavonoids, alkaloids, terpenoids and saponins. A. bisporus has potential as an antidiabetic through the ability to decrease blood glucose, and MDA levels, as well as increase SOD activity in diabetic rats. This research is able to provide information about the antidiabetic potential of A. bisporus extract so that it can be used as an alternative natural antidiabetic agent and can be applied in the community with ease and in a more controlled industrial scale.
