Abstract

Infectious diseases became more serious problem for public health in recent years. Although existing antibacterial drugs have been relatively effective, they do not rule out the emergence of resistance to the drug. Therefore, the intensive exploration of new bioactive compounds from natural, especially peptide compounds began in recent decades in order-handling infection. This study aimed to isolate, purify and test the potential application of Xylaria psidii KT30 extracellular protease as antibacterial agent against Gram-positive bacteria. X. psidii KT30, a marine fungus isolated from red seaweed Kappaphycus alvarezii showed antibacterial activity against Bacillus subtilisand Staphylococcus aureus. Antibacterial compounds of this fungus were predicted as a group of proteases. Extracellular protease exhibited an optimum activity when potato dextrose broth was used as cultivation medium. Furthermore, the highest activity of these proteases was found on fungal extract after day 15 of cultivation with value of 2.33 ± 0.19 U/mL. The partial purification of proteases using G-75 column chromatography resulted in 2 groups of fractions and showed protease activity based on zymogram assay. The extracellular proteases obtained from those fractions have 3 patterns of molecular mass based on sodium dodecyl sulfate–polyacrylamide gel electrophoresis which are 56.62, 89.12, 162.18 kDa.

Abstract

Previous research showed that Stichopus hermannii and Spirulina platensis had an antioxidant activity. It is indicated by the reduced malondialdehyde (MDA) level in the liver of the diabetic rats. However, the STZ administration did not significantly increase MDA concentration of diabetic rats' blood serum for 14 days. This research aimed to determine in vitro and in vivo MDA inhibition of S. hermanii and S. platensis. The in vitro antioxidant activity test was conducted using the MDA-TBA method, and a positive control used α-tocopherol. For in vivo experiment, diabetic rats (DM) were induced by streptozotocin for 21 days. Twenty-five rats which were divided into five groups: normal rat group (NA), diabetic rat group (DA), diabetic rat group + glibenclamide (DG), diabetic rats + Stichopus hermanii (SH), and diabetic rats + Spirulina platensis (SP). The in vitro results showed that the antioxidant activity of 25 ppm Spirulina platensis had the same MDA inhibitory activity as 200 ppm α-tocopherol, but 200 ppm Stichopus hermanii had lower inhibition than 200 ppm α-tocopherol. The in vivo result showed that Stichopus hermanii treatment was more effective in suppressing blood serum MDA concentration, but Spirulina platensis was more effective in suppressing liver MDA concentration.
