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: Liquid organic fertilizer is a fermented solution of organic plant residues, animal and human feces containing nutrients. Lamtoro and tofu liquid waste contain N, P, K, Mg, and Ca, which are suspected to have the potential for liquid organic fertilizer to increase the growth of cayenne pepper (C. frutescens). This study aims to determine the effect of giving POC from lamtoro leaves and tofu liquid waste on the growth of cayenne pepper (C. frutescens). Methods: This study used a completely randomized design (CRD) with two replications. POC volume 1:1 consisted of two-liter lamtoro leaf extract and 2-liter tofu liquid waste. The first factor is the volume concentration of POC with the respective concentrations of V0: 0%, V1: 10%, V2: 20%, and V3: 30%. The second factor is the time of spraying POC T1: 3 days interval and T2: 6 days interval. Parameters measured included plant height (cm), number of leaves (strands), and plant fresh weight (g). Results: 20% volume (V2) with three-day intervals (T1) gave the best results for plant height (20.10 cm), number of leaves (7.00 leaves), and plant fresh weight (11.50 g). 0% volume (V0) with an interval of 6 days (T2) gave the lowest yield on plant height (6.35 cm), number of leaves (3.00 leaves), and fresh weight of plants (3.00 leaves). Conclusions: Application POC from lamtoro leaves and tofu liquid waste can potentially increase the growth of cayenne pepper (C. frutescens).

This pandemic has become a major problem for people, health professionals, and research institutes that how to combat SARS-CoV-2. The objective of this review article is to provide a brief study that CRISPR/Cas9 can be used to combat SARS-CoV-2. Methods: The comparison of three genome editing techniques (ZNF, TALEN, and CRISPR/Cas9) is done. The mechanism of action of CRISPR/Cas9 is discussed. Results: The studies provided in this review article suggest that it is difficult to recognize this virus as they have their own metabolic machinery and they replicate their selves in the host cell and consume host cellular products to perform their own functions. The COVID-19 proteins may contain some specific areas that are suitable targets for therapy, such as tiny inhibitor molecules for viral polymerase, or impede the attachment of viruses to the receptor sites, for example, viral coat proteins can be used for vaccination purposes. Conclusion: CRISPR-Cas9 can be used to control the SARS-CoV-2 genome from replication and spread to other parts of the body as it can edit the genome quite efficiently. This proposed model will help in targeting the SARS-CoV-2 genome more precisely in the future.
