Abstract

Endophytic fungi is a symbiotic microorganism which live inside plant tissues and not harm to their host. Several genera from endophytic fungi known to produce secondary metabolite compounds like antibiotics, anticancer, antifungal, antiviral and antimalarial. This study aimed to investigate antibacterial activity of endophytic fungi from senduduk (Melastoma malabathricum L.) against Escherichia coli and Staphylococcus aureus. Based on the test result, 11 isolates endophytic fungi from senduduk were known to have antibacterial activities. Isolate code 23 have ability to inhibit the growth of E.coli with diameters zone of inhibition is 22 mm and eight isolate endophytic fungi have ability to inhibit the growth of S.aureus (showed by inhibition zone).

Abstract

Escherichia coli is a bacteria that inhabitant in the cattle or human intestine. Raw beef sold in the traditional markets is easily to contaminated by E. coli. It’s because the markets is one of the vulnerable and the risk is high enough against contamination. The goal of this research is to detect E. coli contamination in the fresh raw beef at several markets in Pekanbaru. This research used 100 gr fresh raw beef purchased from the six traditional markets in Pekanbaru. The study begins with a Most probable Number (MPN) test, than isolation and identification of the media ECB and L-EMB, initially with IMViC test (Indol, Methyl Red, Voges Praskauer and Citrate). Results of MPN test showed that all raw beef were contaminated E.coli with MPN varying value.

Abstract

Endophytic fungi are microorganisms living in healthy tissue of their host plants without causing disease. Endophytic fungi live in every plant, including Vetiveria zizanioides L. medicinal plant intracellulary and/or intercellulary. This plant was screened pharmacologically for antibacterial, antifungal, anticataleptic, analgesic and anti-inflammatory, rheumatism, anti oxidant and anti arthritic activity. This research aimed to isolation endophytic fungi from V. zizanioides L. and to screening their antimicrobial potency against microflora Escherichia coli, Staphylococcus aureus, and Candida albicans. Endophytic fungi isolation from V. zizanioides L. was done by surface sterilization method. A total of 33 isolates were recovered from 88 leaves and 88 root segments. Based on antimicrobial activitytest, most of the fungal extracts showed in vitro inhibition of microbes growth.

Abstract

This research aimed to isolate and select endophytic fungi that potentially as antimicrobial from betadin plants (Jatropha multifida L.). Isolation of endophytic fungi was carried out using surface sterilization and selection of endophytic fungi using well diffusion method. A total of 13 isolates of endophytic fungi were obtained from J. multifida L. From a total of 13 isolates, 11 isolates were able to inhibit the growth of Candida albicans, 11 isolate was able to inhibit the growth of Staphylococcus aureus and 10 isolates were able to inhibit the growth of Escherichia coli.

Abstract

Tujuan penelitian ini untuk menguji aktivitas antibakteri isolat aktinomisetes yang telah diisolasi dari tanah Hutan Larangan Adat Ghimbo Potai, Kabupaten Kampar, Provinsi Riau. Penelitian dilakukan pada bulan April sampai dengan Juli tahun 2016. Uji aktivitas dilakukan menggunakan metode difusi agar terhadap 2 bakteri uji yaitu Escherichia coli and Staphylococcus aureus. Hasil uji aktivitas isolat aktinomisetes NA-1 dan NA-2 menunjukkan bahwa hanya isolat NA-1 yang memiliki kemampuan menghambat pertumbuhan bakteri S. aureus dengan diameter zona penghambatan sebesar 7 mm.
