Abstract

Commodity of tea (Camellia sinensis) has an important role in the national economy, especially in the field of agro-industries. Based on data obtained from the Directorate General of Plantation, the tea plant productivity declined over the last few years. This is due to the pest attack which result in decreasing the productivity of the tea plant. Increased crop productivity of tea have been done, such as the use of herbicides and insecticides, but until now there is very little effort to increase the production of tea plants by the use of biological agents. Chryseobacterium sp and Bacillus sp are rhizobacteria in tea rhizosphere that could potentially be used as a biocontrol agent (bioimmunizer). The purpose of this study is to determine the community rhizobacteria in tea soil with the addition of bioimmunizer based on 16S rRNA gene using T-RFLP technique. The method used in this research is T-RFLP technique (Terminal Restriction Fragment Length Polymorphism) using enzymes Msp I and Rsa I. The calculated value are relative abundance, Shannon diversity index (H '), evenness index (E), and dominance index. The results of this study indicate that soil samples with the addition of bioimunizer consisting of Arthrobacter sp, Bacillus sp, Actinobacteria, and Chryseobacterium sp.Keyword: T-RFLP, Chryseobacterium sp, Bacillus sp

Abstract

The public demands for the refill drinking water increases causing the development of refill drinking water industries. However, the problems occurred is no standard method to process drinking water with sterile and lack of government oversight. These cases give rise to sanitation which is the formation of bacteria pathogen forming biofilms in refill drinking water system. One of the bacteria pathogens is Salmonella. Salmonella in refill drinking water can cause diarrhea, because it can produce cytotoxin and enterotoxin. Bacteriophages are viruses that infect bacteria. This study aims to find natural isolates of bacteriophage from biofilm samples to infect Salmonella spp. in refill drinking water system. The isolates obtained is then characterized by biochemical test including Gram stain, a test Kligler Iron Agar (KIA) and api assay 20 E. The positive Salmonella spp. isolates are in the second dilution refill drinking water depot. The isolation of bacteriophage from biofilm is conducted with bacteriophages amplification and bacteriophage filtrate. The Infection test is performed by using Salmonella enterica, Salmonella 7A1 from Teluk Ambon and Salmonella spp. from refill drinking water depot. Platting is performed on serial dilutions of 10-2 to 10-10phage dilution. Positive result is characterized by the formation of plaque which is in source water samples, water product and drinking water depot. The number of plaques formed is calculated by Plaque Forming Units (PFU/mL) to determine quantification or calculation phages.

Abstract

Methicillin Resistant Staplylococcus aureus (MRSA) is a strain of Staphylococcus aureus which has been resistant to methicillin antibiotics and β-lactam group. The mechanism of MRSA resistance occurs because the Staphylococcus aureus produces Penicillin Binding Protein (PBP2a) encoded by the mecA gene that has low affinity to methicillin. Nowadays, MRSA is tested by resistance test using Oxacillin 1 ug. This method requires pure isolate and bacterial culture, so that the results can be seen in 5 days. To find a rapid and precise diagnostic technique for detecting MRSA, mecA gene detection utilizing PCR multiplex technique as the alternative diagnostics. This study aims to find a quick and precise alternative diagnostic technique for MRSA examination, which is utilizing MALDI-TOF MS and multiplex PCR technique.Keywords: MRSA, Staplylococcus aureus, MALDI-TOF MS, Multiplex PCR.
