RESULTS: Aspergillus niger had the highest occurrence in pineapple, watermelon, oranges, pawpaw, and tomatoes with a frequency of 38%. Thin sections of the rotten fruits were obtained using a sterile blade and inoculated onto PDA media and incubation was carried out at 27°C for 5 days. The fungal culture Aspergillus niger used in the present study was isolated from the forest soil [18 Srilakshmi A, Narasimha G. Production of cellulases by fungal cultures isolated from forest litter soil. was the least common. ecosystem particularly soil, often with undesirable effects. | Fruits contain high levels of sugars and nutrient elements and their low pH values make them particularly desirable to microbial decay. This finding was in conformity with that of Bukar et al.8 who reported that Aspergillus species, Mucor and Rhizopus spp. selective and differential media. Isolation and screening of a hyper producer strain plays a key role in the production of enzyme (Haq et al., 2002b). Pathogenicity test: The Pathogenicity test was represented in Table 3. species; Aspergillus flavus and Rhizopus stolonifer in tomatoes. 2012:5–6. Mailafia et al. Alternaria sp. The Aspergillus niger T iegh is a saprotrophic mitosporic wide-spread fungus commonly found in different components of the environment as soils, pictures, walls, indoor air etc. Isolates were screened by a gradient plate assay, and results were confirmed by broth assay. Soil samples collected were taken to the laboratory for isolation of Aspergillus niger using potato dextrose agar (PDA). The point of inoculation of each type of fungus was examined and recorded. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Care should be taken during handling of these fruits and improved technology based preservation methods are suggested to enhance the keeping quality of fruits. Pathogenicity test: Pathogenicity test was carried out to know if the isolated fungi were really responsible for the spoilage of the fruits. Abstract An indigenous lead‐tolerant fungal strain was isolated from lead‐contaminated soil and identified as Aspergillus niger, via 18S rRNA gene sequencing. doi: 10.1016/j.btre.2020.e00496. | Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. The morphologic identification proved useful for some species, such as A. carbonarius and Aspergillus sp UFLA DCA 01, despite not having been totally effective in elucidating species related to A. niger. Isolated Fungi 1 Aspergillus sp. All the Aspergillus niger isolates demonstrated the potential for pectinase production. Isolation and identification of some fruit spoilage fungi:Screening of plant cell wall degrading enzymes. Epub 2019 Nov 29. The study reveals the potential of various A spergillus niger isolates from different soil in the production of pectinase. The use of microbial technologies in agriculture is currently expanding quite rapidly with the identification of new bacterial strains, which are more effective in promoting plant growth. The isolation was directly from the agricultural soils and decaying woods materials. Background and Objective: Fruits are subjected to natural contamination by many different kinds of micro-organisms, including pathogens such as fungi. The pathogenic fungi species associated with fruits spoilage in this study are of economical and public health significance. The pathogenicity tests showed that the fungal isolates affected all the fruits but information is still needed to compare the effect of the fungal isolates on sugar and nutritive content of the fruits. The finding was also in conformity with the findings of Gadgile and Chavan19 on the isolation of fungal pathogens from fruits stored and sold in the market. While, Aspergillus flavus occurs in pineapple, pepper, tomatoes and banana. Public health risks related to food safety issues in the food market: a systematic literature review. However, the pathenogenicity of Rhizopus stolonifer was higher than that of the remaining fungal species isolated, while that of Alternaria sp. 1979;23(2):105-9. doi: 10.1002/food.19790230202. The result of this study revealed the presence of 7 different fungal species from deteriorated fruits obtained from Utako market. Microorganisms play an However, Rhizopus stolonifer occurred in pepper, tomato, water melon, pumpkin and pawpaw and Mucor mucedo occurs in only tomato and pawpaw. In the present study 18 strains of Pseudomonas were isolated from soil sample of Balochistan coastline. Ann For Res 2012; 55(1): 85-92. Cylindrical plug tissues were cut out from the fruits using a sterilized 2 mm sized cork borer. Materials and methods: It’s 28S rDNA sequence also had some significant identity (>90%) with different subspecies of Aspergillus. The result also showed that Alternaria sp. The soil fungi were isolated by the soil dilution Figure 3: A. (Aspergillus japonicus), C. (Aspergillus flavus), 2018 Jan 5;13(1):e0190236. Isolation and identification of Aspergillus niger Aspergillus niger was isolated from soil by serial dilution technique. The significance for high incidence of section AspergillusFlavi is in regard to their The spoilt fruits were identified by morphological examination using the method of Bukar et al.8. Annual reports have shown that 20% of fruits and vegetables produced are lost to spoilage. Some of these isolated fungal species produce toxins that could cause severe food poisoning and other potential health hazards. Aspergillus were dominant. A small portion of the aerial mycelia from the representative culture was picked using a sterile inoculating needle and inoculated on a slide containing a fraction of a prepared solidified potato dextrose agar and incubated for 48 h, after which it was viewed under the light microscope first with low resolution objective of x10 and then with high resolution objective of x40 to detect spore, hyphae and other special structures according to the methods described by Barnett13. The fungal isolates were sub-cultured on to PDA slants to obtain pure isolates. Purpose: Isolation and identification of microorganisms associated with engine oil contaminated soil was carried out. Mycopathologia. had the least pathogenicity of 20 mm in diameter rotten surface. Kutsai et al. 2019 Nov 30;24(1):68. doi: 10.1186/s12199-019-0825-5. Acta Hortic. The collected soil samples were brought to the laboratory for microbial isolation. However, Aspergillus niger. MBFA18 produced by A18 showed excellent flocculating efficiency under the optimal cultivation condition (PSW with the addition of 5950 mg/L COD, 20 g/L glucose dosage, 10 g/L urea and without the addition of phosphorus source … Culture media preparation: Potato Dextrose Agar (PDA) containing chloramphenicol (30 mg mL1) were used. Aspergillus fumigatus and Mucor species Singh D, Sharma R.R. was carried out by culturing on potato dextrose and sabouraud’s dextrose agar media and microscopic method. Thus a new theory on microbial spoilage may be arrived at. The media were cotton plugged and wrapped with aluminium foil and were autoclaved at 121°C at a pressure of 15 Ibf/in2 for 15 min. occurred only in oranges and Aspergilus fumigatus in pineapple and pawpaw.

The quantities of the appropriate medium or base medium were weighed. This study revealed that PSW could serve as a suitable substrate for the bioflocculant producing microorganism- Aspergillus niger (A18) isolated from soil sample. Al-Hindi R.R, Al-Najada A.R, Mohamed S.A. Soil is a multi-layered surface complex of mineral and organic constituents present in solid liquid and gaseous states. Several studies have also reported that Aspergillus spp. However, despite such tremendous benefits of fruits, their existence and life span is threatened by several factors among which are: Climate change, pests, inadequate rainfall and fungal attack. A total of 100 spoilt fruits which include pawpaw (Carica papaya), orange (Citrus sinensis), tomato (Lycopersicon esculentum), pineapple (Ananas comosus), and watermelon (Citrullus vulgaris) were purchased and examined for the presence of fungal organisms using standard methods. 2 and Chukwuka et al . They are dangerous even in minute quantities and present extreme toxicity due to their ability to withstand heat5. Identification of fungal isolates: Fungal isolates obtained from the slant were identified based on their gross morphology such as colony growth pattern, conidial morphology and pigmentation by slide culture techniques12. Results: Aspergillus niger had the highest occurrence in pineapple, watermelon, oranges, pawpaw, and tomatoes with a frequency of 38%. Get the latest research from NIH: https://www.nih.gov/coronavirus. Introduction. Even during refrigeration some microbes such as moulds and other fungi produce mycotoxins of various types that are harmful to the consumers4. The procedure was repeated separately across each of the fungal isolates. However, the value obtained for the prevalence of A. niger which caused a disease called black mold on certain fruits and produced potent mycotoxins called ochratoxins that can be harmful to human beings and animals, was higher than the one reported by Mailafia et al.18 who reported the highest occurrence of 38%. Isolation and identification of Rhizosphere Mycoflora of Lycopersicum Esculentum (tomato). Other fungal organisms such as yeast (Saccharomyces species), P. digitatum and R. stolonifer were isolated with varying prevalence (40%, 20%, and 5%) from watermelon, tomato, and orange, respectively. Isolation, Characterization and Identification of Thiram-degrading Microorganisms from Soil Enrichment Cultures Nurettin ŞAHİN Muğla University, Faculty of Arts and Sciences, Department of Biology, ... biochemical tests fungi were identified as Aspergillus niger, A. flavusand Penicilium steckii. Fusarium avenaceum followed with the frequency of occurrence of 31% in fruits such as pineapple, watermelon, oranges, pawpaw, and tomatoes while Penicillium digitatum and Rhizopus stolonifer had the least frequency of 4% each in tomato; and … Furthermore, Bali et al.20 stated that A. niger was the cause of post-harvest spoilage in sweet orange and acid lime at field. Most of the fungal organisms isolated in this study played a great vital role in causing fruits spoilage. These fungal species were confirmed to be causative agents of the spoilage. NLM These mycotoxins have low molecular weight and toxic secondary metabolites from some species of fungi. Spoilage micro-organisms can be introduced to the crop on the seed itself, during crop growth in the field, harvesting and post-harvest handling or during storage and distribution loading and offloading7. Isolation of Fungi . Prevalence of fungal isolates: The prevalence of fungal isolates on the spoilt fruits samples from Utako market was shown in Table 2. (Aspergillus niger), B. We … frequency of occurrence; fruits; fungi; pathogenic; prevalence. Glycaemic response to some commonly eaten fruits in type 2 diabetes mellitus.
