Abstract

Fifteen Streptomyces isolates were isolated from soil in some different location on vegetable plantation at agriculture standard condition. The isolates were assessed for their antibacterial activity against Mycobacterium tuberculosis (MTB) ATCC H37RV and mycobacterial which isolated from Dr. Soetomo Hospital patients in Surabaya. The Interna-tional Streptomyces Project 4 (ISP4) and Middlebrook 7H9 (MB7H9) wwere used as growth or fermentation medium. The screening of inhibition activity was performed using turbidimetry and spot-test on agar medium. Results shown that 33.3% of the isolates (5 isolates) have anti-mycobacterial activities. The first line anti tuberculosis drug rifampicin, (RIF), ethambutol (EMB), isoniazid (INH), and pyrazinamide (PZA) were used as standards or positive controls with concentration 20 ppm. Optical density of crude fermentation broth concentrated from five isolates relatively lower than five anti-tuberculosis drug activity standard, although their activities against some microbial were similar to the stand-ard at spot-test. The most efficient isolate shown anti-mycobacterial activity was Streptomyces B10 which identified as Streptomyces violaceousniger. In addition, fatty acid methyl ester (FAME) profile of gas chromatography-mass spec-trometry chromatogram of each isolates were studied and compared to Streptomyces spp.

Abstract

Shiitake mushroom (Lentinus edodes) is one of the wood mushroom types that can be consumed as a food as well as for a medical purpose. Lentinan, a polysaccharide contained in shiitake, is well known for its use on cancer medication. Mycelium of Shiitake mushroom contains lentinan the same as other part of the mushroom like fruity body. Toxicity of the lentinan in mycelium compare to the fruity body has been first conducted by using Brine Shrimp Lethality Test (BST). Using Potato Dextrose Broth media with the growth rate of 3.88% did mycelium multiplications. Probit analysis showed that the toxicity of the mushroom’s cap, stem, and mycelium of Shiitake mushrooms is LC50 = 648.76507 mg/ml LC50 = 489.39444 mg/ml, and LC50 = 481.16941 mg/ml respectively.

Abstract

This study aims to determine the minimum inhibitory concentration (MIC) and bactericidal concentration (MBC) of the fermentation filtrate (FF) on red passion fruit pulp (Passiflora edulis Sims.) against Escherichia coli Extended Spectrum Beta Lactamase (ESBL) and Methicillin Resistant Staphylococcus aureus (MRSA). The method used was the fermentation of red passion fruit pulp for 24 h using De Man Rogosa Sharpe Broth (MRS-broth) media, and the result showed that the FF of red passion fruit pulp made a dilution series concentration of 50%, 25%, 12.5%, 6.25%. Considering this result, the MIC FF of red passion fruit cells against ESBL and MRSA has a 25% dilution concentration, while MBC has a 50% dilution concentration. This shows that red passion fruit has the potential to be developed as antibacterial material, especially to fight bacteria that are already resistant.
