Abstract

Background: A public burial place (TPU) is used to bury the dead. There is an active decomposition of corpses in the soil, which produces soil nutrients and minerals that can support the growth of microorganisms in the ground, including pathogenic bacteria. Pathogenic bacteria have a more severe impact if they are resistant to antibiotics. Methods: Soil samples were taken in the Bonoloyo TPU area, Surakarta, Central Java, at 3 points each of 2 depths of 20 and 50 cm. Soil samples were inoculated on NA (Nutrient agar) media using the spread plate method. After 48 hours, colony counting and morphology observations were carried out, followed by gram staining. Isolated bacterial isolates were tested for resistance to 3 types of antibiotics. Results: The average population of soil bacteria in blocks 12, 17, and 21 at a depth of 20 cm is 4 x 10⁶ CFU/g; 8 x 10⁶ CFU/g; and 1 x 10⁶ CFU/g, while at a depth of 50 cm, it is 2.3 x 10⁶ CFU/g; 6 x 10⁶ CFU/g; and 4 x 10⁶ CFU/g. The morphology of bacterial colonies is irregular (26 isolates), flat elevation (19 isolates), and the color of isolates is predominantly white. The Gram staining results obtained 23 isolates are Gram-negative, and 22 are Gram-positive with a dominant cell form in cocci. Antibiotic resistance tests showed that the bacterial isolates were resistant to ampicillin (28.9%), Bacitracin (64.4%), and Cefepime (57.8%). Conclusions: Burial soil bacterial populations at Bonoloyo TPU at different depths did not differ markedly, with numbers ranging from 1 - 8 x 10⁶ CFU/g.

Abstract

Background: A public cemetery (TPU) is where bodies are buried. Before being buried, the body is wrapped in a shroud or full clothes and sometimes put in a coffin. These materials contain cellulose, a substrate for cellulolytic microorganisms, including bacteria, to decompose. Exploration of cellulolytic bacteria in TPU has not been found, even though TPU holds potential cellulolytic bodies. This study aims to determine the cellulolytic potential and identify bacterial isolates from TPU. Methods: 36 bacterial isolates tested for cellulolytic potential have been isolated from TPU Pracimaloyo Kartasura, Sukoharjo. Selection of cellulolytic bacteria used selective Carboxymethyl Cellulose (CMC) media dripped with Congo red 0.1%, while identification was based on colony morphology and Gram staining. Results: This study obtained one isolate (2.78%) showing high cellulolytic activity with a cellulolytic index (IS) 7, namely P14, 24 isolates (66.67%) in the "moderate" category, four isolates (11.11%) with category "low," and seven isolates (19.44%) did not show cellulolytic ability. Isolates cellulolytic positive have a shiny white colony color, entire edges, raised elevation, and belong to the Gram-negative coccus form. Conclusions: From the results of this study, it can be concluded that public burial sites (TPU) harbor potential cellulolytic bacteria.

Abstract

Background: Plants’ response and antagonistic reaction against disease-causing organisms are two crucial characteristics of Plant Growth Promoting Bacteria (PGPB). Seventeen endophytic bacteria have been isolated from Musa balbisiana. However, the plants’ reaction against these isolates and their antagonistic activities against disease-causing organisms remained unknown. This study aims to (1) determine the sensitivity effect of endophytic bacteria isolates to tobacco and (2) test the antagonism of endophytic bacteria isolates against the blast disease actor, namely Pyricularia oryzae. Method: Sensitivity tests were performed by inoculating bacterial isolates into tobacco leaves with infiltration. Bacterial isolates were prepared with a minimum OD 600: 0.5. Then, a milliliter volume of each isolate was infiltrated into tobacco leaves from the abaxial side using a 3 mL syringe. The lesion on the tobacco leaves was observed seven days after inoculation (DAI). The antagonism test was carried out by growing Pyricularia oryzae on a PDA plate for seven days, subsequently transferred to an NA medium for three days then inoculated with endophytic bacteria. The assessed parameter of the antagonistic test was the formation of an inhibitory zone between endophytic bacteria and Pyricularia oryzae at 4 DAI. Results: No hypersensitive reaction of tobacco leaves against K117, K324, K38, K86, K18, K28, K102 isolates inoculation at 7 DAI. Furthermore, the antagonistic test indicated that all isolates inhibited the growth of Pyricularia oryzae, with the range of inhibition from 32.36 to 40.46%. Implication: Thus, these results revealed the PGPB characteristics in the newly isolated endophytic bacteria from the banana.

Abstract

Background: The cemetery is an area for the burial of corpses so that active decomposition of bodies occurs. One of the decomposition bacteria that might be found is lipolytic bacteria because the human body comprises 21,33-32,51 % lipids. Explorations of lipolytic bacteria from cemeteries in Indonesia have not been found, so this research needs to be done. This non-experimental study aimed to select and identify lipolytic bacterial isolates from the Pracimaloyo cemetery, Surakarta. Method: A total of 36 bacterial isolates were selected for their lipolytic activity using tributyrin media. The lipolytic index determines lipolytic activity. Identification of lipolytic bacteria based on colonial morphology and Gram staining. Result: The study showed that 22.2% (8 isolates) showed a lipolytic positive, with the largest lipolytic index (LI) value of 2.5 (isolate P36). Bacterial colonies are circular-shaped, have entire edges, flat elevation, and are yellow or white. Gram staining results showed that the isolated is a group of Gram-negative bacteria in the form of coccus. Conclusion: The conclusion of this study suggests that bacterial isolates from Pracimaloyo cemetery that have potential lipolytic activity, which is likely to be from the genera Pseudomonas and Klebsiella, were obtained.
