Abstract

The cucumber harvests failure occurred mainly due to the destruction of crops by the leaf-eating beetle A. similis Oliver. Many ways are taken especially pesticides that are synthesized widely because it is considered the fastest and most potent to overcome pest disorders. Based on, one of the control techniques that can be used is PGPR, which is a group of bacteria that can be utilized to strengthen plants against pest attacks and plant diseases, so research needs to be done by using this technique to change the feeding behavior of the A. similis Oliver beetle on cucumber plants. The research was conducted at the Green House Department of Pest and Plant Diseases University of Brawijaya Malang in September 2018 to March 2019. It was conducted using Randomized Block Design (RBD) 5 treatment, i.e., PGPR, urea fertilizer and control (without treatment). Based on the results of the study shows that: Application of PGPR on cucumber plant can reduce damage on either leaves or flower due to the eating behavior of imago A. similis Oliver and Application of PGPR can increase the cucumber plant growth during the eating behavior of imago A. similis Oliver.

Abstract

Anthracnose disease is a major disease in cayenne pepper triggered by fungal pathogen Colletotrichum capsici which can cause yield losses of up to 90%. Control of disease generally utilizes synthetic fungicides, but it damages the environment and human health. Hence, alternative controls that are ecofriendly are required. One of the attempts is to make use of chitinolytic bacteria's potential. This study aimed to screen UB Forest chitinolytic bacteria and to determine their potential in suppressing anthracnose in cayenne pepper. Stages of research include a screening of 78 UB Forest bacteria as chitinolytic bacteria, selection of chitinolytic bacteria that are antagonistic against C. capsici, inhibition test of chitinase crude extracts against C. capsici growth, controlling anthracnose disease in cayenne using chitinolytic bacteria, and molecular identification. Based on the results of the selection, there were 76 isolates of UB Forest bacteria classified as chitinolytic bacteria, 74 bacteria antagonistic against C. capsici. Chitinase crude extracts significantly affected C. capsici growth inhibition compared to fungicide treatment. The application of Pseudomonas aeruginosa (UB 11) and Bacillus cereus (UB 12) can control anthracnose disease in cayenne pepper with the intensity of 41.67% and 38.89% respectively with the efficacy level of 58.33% and 61.11%.

Abstract

Nutmeg is a spice that might be susceptible to being infected with aflatoxigenic fungi. Aflatoxins are mycotoxins synthesized by certain strains of Aspergillus section Flavi. However, not all strains are able to produce aflatoxins. The approach frequently employed for this survey comprises the cultivation of strains in a suitable liquid or solid medium and their subsequent extraction and analysis for the presence of aflatoxins. To date, very few studies have been conducted on the identification of contaminate and aflatoxigenic fungi in Myristica fragrans. Therefore, this study aimed to identify the contaminate and aflatoxigenic fungi in Myristica fragrans growing on V8 and CAM Media. Isolation of the fungus was carried out by direct agar plating. Lasiodiplodia theobromae, Aspergillus niger, A. tamarii, Penicillium citrinum, Rhizopus delemar, A. nomiae, and A. aflatoxiformans were recovered from nutmeg kernels sampled from North Minahasa, North Sulawesi, Indonesia. The findings of fungal isolation demonstrated that L. theobromae was the most prevalent form of fungus detected in the nutmeg kernels (50%), followed by A. niger (38.13%) and A. tamarii (10%). A. nomiae and A. aflatoxiformans were the aflatoxigenic fungi isolated from M. fragrans kernels.

Abstract

Platycerium elephantotis, an African epiphytic fern thriving in Indonesia, is prized for its ornamental value and medicinal potential. It aids in fern succession without harming its host, obtaining nutrients from leaf litter and roots. Special water-storing tissues and CAM photosynthesis enhance its resilience. Endophytic bacteria in its roots likely contribute to nutrient absorption, including phosphate solubilization and nitrogen fixation, similar to other fern species. Studies on these bacteria are crucial for enhancing agricultural practices by reducing chemical inputs and promoting plant growth as plant growth-promoting bacteria (PGPB), particularly in nitrogen fixation and phosphate solubilization. The research was conducted from November 2023 to January 2024. Plant samples were collected from Arjuna Park Conservation Garden, Malang, and endophytic bacteria were isolated using serial dilution and nutrient agar media. Hypersensitivity, phosphate solubilization, and nitrogen fixation tests were conducted to assess bacterial traits. The study obtained six bacterial isolates (PE 5, PE 7, PE 24, PE 25, PE 30, and PE 49) from P. elephantotis with potential as biofertilizers due to their nitrogen-fixing and phosphate-solubilizing abilities. The diverse colony morphologies indicate different bacterial species. All isolates are rod-shaped (bacilli). Gram staining shows that PE 25 and PE 49 are gram-negative, while PE 5, PE 7, PE 24, and PE 30 are gram-positive.

Abstract

Ralstonia solanacearum, the causal agent of bacterial wilt disease is worldwide in distribution, and results in serious economic losses, particularly in the tropics. Detection and characterization of microorganisms by Fourier transform infrared spectroscopy (FTIR) technique promises to be of great value because of the method’s inherent sensitivity, small sample size, rapidity, and simplicity. In this study, we used FTIR spectroscopy for the characterization of Ralstonia solanacearum. The bacteria were grown on Nutrient Agar (NA) at 28°C for 48 hours. The colonies of Ralstonia solanacearum on nutrient agar medium were smooth circular, raised, and dirty white. Cultures of bacteria were identified by molecular methods using PCR techniques. The DNA was amplified using a specific primer pair, 759f/760r (forward primer: 5'- GTCGCCGTCAACTCACTTTCC 3’, reverse primer: 5'-GTCGCCGTAGCAATGCGGAATCG-3’). The PCR produced a single band of 280 bp from the isolated DNA of cultured bacteria.  Bacterial spectra were obtained in the wavenumber range of 4000–400 cm-1 using FTIR spectroscopy. The identification of cell wall constituents in region 3000–2800 cm-1, the proteinaceous structure of bacteria in region 1665–1200 cm-1, and the fingerprint of bacteria in region 1200-800 cm-1 are all part of the spectra analysis in this study. Absorption bands obtained from bacteria Ralstonia solanacearum samples associated with protein, phospholipids, nucleic acids, and carbohydrates appear in the bacterial IR absorption spectra.

Abstract

The presence of Bacillus mycoides and its ability to grow and spread quickly certainly affect the growth of the target pathogen and it can cause invalid detection results. Therefore, the presence of contaminant bacteria needs to be detected to ensure the specificity of the detection results against the target pathogenic bacteria. Various kinds of detection methods are commonly used, such as ELISA (enzyme-linked immunosorbent assay) and PCR (polymerase chain reaction) are time-consuming and not always very specific. Fourier-transform infrared (FTIR) spectroscopy methods were adopted to provide a comprehensive and reliable method for bacterial analysis. In this study, FTIR spectroscopy was used as an initial guess for the identification of bacterial isolates. Our results showed that there are dominant peaks from the FTIR spectrum obtained that were most associated with protein and carbohydrate in the range of wave number 400-4000 cm-1.

Abstract

The detection and identification of microorganisms using spectroscopy techniques promise to be of great value because of their sensitivity, rapidity, low expense, and simplicity.  In this study, we used FTIR spectroscopy for the characterization of Fusarium solani. PCR amplification of DNA extracted from these isolates showed the possibility of amplifying PCR products with sizes 559 bp using the ITS1-ITS4 primers. Based on phylogenetic tree analysis, the isolate of F. solani showed a closely relationship to Fusarium solani isolate MN (MH300495.1) with 99.63% similarity.  The study is focused on the carbohydrate structure which can be analyzed in the range of 900 to 1200 cm-1 of FTIR wavenumber.  The spectra of our samples share similarities with one another, although small differences occur in the absorbance value. The band at 1027 cm-1 is assigned to the C-O stretching of glycogen. Meanwhile, at 1042 cm-1 is interpreted as carbohydrate C-O stretching as well. The band around 1073 cm-1 might arise from both chitin C-C stretching and phosphate stretching of nucleic acids. Other vibrations associated with chitin are also found at 1115 cm-1 and 1151 cm-1 which are assigned to C-O-C symmetric stretching and C-O-C asymmetric stretching, respectively.

Abstract

One of the potentials of Bacillus cereus bacteria is as an inducer of systemic resistance in plants against plant diseases. FTIR spectroscopy is a traditional method extensively utilized in the pharmaceutical industry, since it is fast, non-destructive, and requires minimal sample preparation. In this study, the indicators that were effectively discovered were the functional groups that compose carbohydrates and lipids. The absorption region to be analyzed for the functional groups that compose carbohydrates is in the wavenumber region of 1200-800 cm-1, whereas the functional groups that compose up lipids are in the wavenumber range of 3020-2800 cm-1 and 1800-800 cm-1. The signal produced on the spectral signature of B. cereus isolates revealing the functional groups that compose carbohydrates is at the absorption values of 1185, 1132, 1122, 1098, 1078, 1056, 1010, and 973 cm-1. This is analogous to the notion that the cell wall of B. cereus is composed of peptidoglycan which contains carbohydrates. While the absorption values that indicate the functional groups that make up lipids are 2969, 2955, 2925, 2870, 2846, 1759, 1733, 1471, 1455, 1234, 895 cm-1, which according to the literature suggests that the body structure of B. cereus contains 2-3% of the dry weight of bacterial cells and consists of neutral lipids and phospholipids.
