Opis:
The need for new drugs is increasing in the antibiotic field. However, synthetic antibiotics often have a bad impact on body health, hence, in this paper, endophytic bacteria is investigated as an antibiotic source. The purpose of this research is to gain an understanding of the antibacterial potency of the endophytic bacteria associated with the Bignay plant (Antidesma bunius) against pathogenic bacteria that is Gram-negative i.e Salmonella thypimurium ATCC 14028, Escherichia coli ATCC 35218 and Gram-positive i.e Staphyllococcus aureus ATCC 6538. This research used the descriptive method and consists of endophytic bacterial isolation, identification, and antimicrobial testing. The endophytic bacterial isolation from fruit and stem of Bignay plant was performed by using the pour plate method, while the bacteria was identified by applying a biochemical test method using Vitek 2.0. The antimicrobial test was performed by way of paper disc diffusion. The resulting endophytic bacteria isolated from the fruit and stem of the Bignay plant are Bacillus pumilus, Bacillus amyloliquefaciens, Bacillus cereus, Bacillus sp.1, and Bacillus sp.2. The most potential endophytic bacteria as antimicrobial against pathogenic bacteria were found to be Bacillus pumilus, Bacillus sp.1, and Bacillus sp.2.

Opis:
Oily sludge is categorized as one of the hazardous wastes that needs to be remediated in order to convert it into a non-toxic compound. Bioremediation involves microorganisms, such as fungi. In the present study, the indigenous oily sludge fungi, Penicillium chermesinum was used to assess the bioremediation. The aim of this study was to obtain the growth profile of Penicillium chermesinum Biourge in reducing the Total Petroleum Hydrocarbon (TPH) and Polycyclic Aromatic Hydrocarbons (PAH) compounds in oily sludge. A descriptive method was applied in this study that consists of the preparation stage and the biodegradation stage of oily sludge. Biodegradation process was performed by using the Solid State Fermentation methods during 15 days with the addition of 10% of fungi inoculum from the total of fermentation medium (100 g). The observed parameters are the TPH, PAH content, and fungi growth profile that were measured using the Gravimetric, GC/MS and TPC analysis. Our results showed that the TPH content was reduced 29.16% from the control. We identified two degraded PAH compounds, namely Azulene (C10) and Fluoranthene (C16).
