Abstract

Green macroalgae Caulerpa racemosa from the waters of Lemukutan Island was isolated to obtain its endophyte fungi. Endophyte fungi were explored to determine their potential as antibacterial. Isolation of endophyte fungi was carried out by dilution method using PDA media. Endophyte fungi with different morphology were obtained as many as 4 isolates, named CRF1, CRF2, CRF3 and CRF4. Antibacterial activity testing was carried out by agar diffusion method. Endophyte fungi isolate CRF3 showed the best activity against Escherichia coli bacteria while CRF2 isolate showed the best activity against Staphylococcus aureus with inhibition zone diameters of 15.83 mm and 11.99 mm, respectively. Keywords:Endophyte Fungi, Caulerpa racemosa, Antibacterial, Lemukutan

Abstract

Percission and accurate gas chromatographic method for determination of propionic acid in bakery products was developed. Bakery productswere directly extraction with ethyl acetat and phosphoric acid used for acidic. The extract was injected directly to gas chromatographic using butyric acid as internal standard. Calibration curve propionic acid range 25 – 1000 µg/mL. Coefissien of variation (CV) rates for spiked bakery produtcs were 1,36% and 99,81% (range 96,32 – 103,61%) for accuracy at ± 1000 mg/kg propionic acid, Limit detection (LoD) and limit quantitation (LoQ) by this method were 333,6537 mg/Kg and 635,5818 mg/Kg. Burger, hot dog, and sandwich buns from a local factory at Pontianak were analyzed and respectively rates less than the limit permitted by Indonesian regulations.
