<p>The post-harvest fungi is one of the greatest cause of various diseases. Particularly, in fungus that infects seeds, the toxic substance called aflatoxin is found. This has caused us to wonder: Has fungi been pathogenic fungi since the beginning of creation? The purpose of this research is to study: 1) The Place of Fungi in God’s Original Creation and the Origin of Pathogenic Fungi, 2) Characterization of post-harvest fungus on corn seeds, 3) Aspergillus sp.’s Structure as Proof of God’s Wonderful Original Creation and Providence, and 4) The factors that contribute to the growth of fungi in post-harvest corn seeds and our responsibility. We conclude that in the beginning, fungi were a part of God’s originally good and perfect creation. These fungi were created by God with the structure and function to support its operation in fulfilling God’s creative purpose. The complex structure of Aspergillus niger and Aspergillus flavus that infected the corn seeds showed God’s providence after the Fall. Pathogenic fungi were the result of the Fall of man into sin. Their growth is caused by the failure to give proper care to the crops. But this should not discourage us since the Bible tells us that God is continually working to restore His creation. Therefore, we are called to be stewards of His creation, to develop and preserve whatever is entrusted in our hands, including the crops for God’s glory and under His authority until He has fully renewed and restored everything.</p><p><strong>BAHASA INDONESIA ABSTRACT:</strong> Jamur pasca panen merupakan salah satu penyebab terbesar timbulnya berbagai penyakit, khususnya disebabkan oleh jamur yang menginfeksi biji-bijian dan menghasilkan substansi beracun disebut dengan aflatoksin. Keadaan ini menimbulkan pertanyaan apakah jamur patogenik ada sejak awal penciptaan? Penelitian ini bertujuan untuk mempelajari: 1) Posisi jamur patogenik di awal penciptaan dan asal mula jamur patogenik, 2) karakteristik jamur pasca panen pada biji jagung, 3) struktur <em>Aspergillus</em> sp sebagai bukti dari providensi Allah akan ciptaanNya yang sangat luar biasa, 4) faktor-faktor yang berkontribusi terhadap pertumbuhan jamur pasca panen biji jagung dan Tanggung jawab kita. Dari hasil penelitian ini disimpulkan bahwa pada mulanya, jamur merupakan bagian ciptaan Allah yang sungguh amat baik dan sempurna. Struktur yang kompleks dari <em>Aspergillus niger</em> dan <em>Aspergillus flavus </em>yang menginfeksi biji jagung menunjukkan providensi Allah setelah kejatuhan dosa. Pertumbuhan jamur patogenik merupakan gambaran kejatuhan manusia ke dalam dosa yaitu kegagalan manusia untuk memberikan pemeliharaan yang memadahi pada biji-bijian pasca panen. Namun demikian, keadaan ini tidak mematahkan semangat kita karena Alkitab mengatakan bahwa Allah masih terus bekerja untuk memulihkan ciptaanNya. Oleh karena itu, diharapkan kita semua menjadi pelayan atas ciptaanNya untuk mengembangkan dan menjaga apa yang dipercayakan kepada kita di bawah otoritasNya termasuk biji-bijian untuk memuliakan Allah hingga Dia secara penuh memperbaharui dan memulihkan segala sesuatu</p>

Abstract. Soesanto L, Hartono ARR, Mugiastuti E, Widarta H. 2020. Seed-borne pathogenic fungi on some soybean varieties. Biodiversitas 21: 4010-4015. The present study was conducted to detect and identify seed-borne pathogenic fungi in some soybean varieties and their effect on seed germination. Experiment was performed in a completely random design with eight treatments and four replicates. Eight soybean varieties i.e., Malabar, Kaba, Dering, Detam I, Sinabung, Dena, Gepak Kuning, and Slamet were selected for the investigation. Seed borne fungi were isolated using blotter test and agar plate techniques. The variables observed were morphological/cultural characteristics, microscopic features of fungi, and percentage of seed germination. A total of eight fungi namely Aspergillus flavus Link, Aspergillus niger van Tieghem, Cladosporium oxysporum Berk. & M.A. Curtis, Colletotrichum dematium (Pers. et Fr.) Grove f.sp. truncate (Schw.) Arx, Curvularia pallescens Boedijn, Fusarium solani (Mart.) Sacc., Melanospora zamiae Corda, and Nigrospora sp. Mason were isolated from different varieties of soybean seeds. The highest seed germination was found to be 80.5% in Daring and Detam I varieties, respectively, and the lowest 53% was recorded in Dena variety.

Aims: The study aims to identifying the microorganisms associated with post-harvest rot of frafra potatoes in Bongo-soe, Upper east region of Ghana. Place and Duration of Study: Department of Horticulture and the Pathology laboratory of the Faculty of Agriculture, Kwame Nkrumah University of Science and Technology (KNUST), Kumasi, Ghana. The Solenostemon rotundifolius tubers were stored at the Horticulture Department laboratory whiles rot identification was carried out at the Pathology laboratory of the Faculty of Agriculture. The Tubers were stored from 2nd November, 2012 to 22nd March 2013. Methodology: Four hundred (400) tubers of black cultivar and four hundred (400) tubers of a brown cultivar of Solenostemon rotundifolius tubers showing visible signs of rot during the storage were collected. Pieces of diseased tissues from the margin of the necrotic collected and immersed in 10% commercial bleach solution for sterilisation, for one minute. These were then blotted dry and plated on Potato Dextrose Agar PDA. The plates were sealed with a cellotape until growth occurred. Results: The microorganisms identified to be responsible for causing rot in Solenostemon rotundifolius tubers were six in number. Colletotrichum gloeosporioides was identified to be responsible for 30.76% of rots observed, followed by Aspergillus niger, 23.07%, Curvularia lunata, 19.23%, Aspergillus flavus, 11.54%, Trichoderma sp and Penicillium sp both recorded 7.70% of rots observed. The percentage incidence of Aspergillus niger (15.38%), Curvularia lunata (11.54%) and Aspergillus flavus (7.69%) was higher in the black cultivar as compared with the brown cultivar which had percentage incidence of 7.69%, 7.69% and 3.85% respectively. Also, the percentage incidence of Colletotrichum gloeosporioides (15.38%) and Penicillium sp (3.85%) was the same in both the black and brown cultivars of Solenostemon rotundifolius tubers used in this study. Conclusion: The activities of the damaging microorganisms can be reduced by controlling mechanical injury during harvesting, transportation and storage of Solenostemon rotundifolius tubers should be prevented or reduced because they pave the way for tuber infection by the rot causing microorganisms.

This research was conducted to determine the fungal pathogens responsible for post harvest losses of pineapple sold at Wudil and Yen lemo markets.  Two samples of pineapples were purchased twice a week from both Wudil and Yanlemo markets for four months. The samples were investigated for the presence of fungal pathogen using standard microbiological methods. The methods involve mounting small portion of pineapple in the plate containing Potato dextrose agar to isolate the fungi. Three fungal pathogens belonging to Aspergillus species were isolated, and Aspergillus niger had the highest frequency of occurrence of (50%). Followed by A. flavus with (27%). The A. fumigatus had the lowest frequency of occurrence of (23%). The differences between the fungal isolates recorded were significantly different (P<0.05) between the two markets, where higher fungal isolates were recorded at Yanlemo market 159 (40.6%) and Wudil 38 (9.71%). The study showed that the post harvest losses of pine apple in the two markets are attributed to fungal infection. Therefore, safe guarding the two markets from debris and dumps of rotten fruits and vegetable may assist in reducing fungal inoculums in the two markets.

This study was carried out for four month (September, 2015 to December, 2015) to find the fungal species associated with post-harvest spoilage of pawpaw fruits sales at Na’ibawa and Wudil Markets all in Kano State. A total of five strains of fungi were isolated and identified as Aspergillus niger, Aspergillus flavuus, Rhizophus stolonifer, Yeast, and Fusarium. Pathogenicity test of each fungal isolate showed that all fungi were capable of causing rotting of the fruit and most severe rotting was caused by Aspergillus niger and Yeast with 8(29.63%) Respectively at Na’ibawa market and 10(34.48%) and 9(31.03%) at Wudil market followed by Rhizophus with 7(25.93%) and 5 (17.25%) while Aspergillus flavus and Fusarium produced the least rotting of the fruit. The difference in the fungal spoilage of Carica papaya between the two market areas Na’ibawa and Wudil markets was statistically significant (p≥0.05). From the result of this study, it is clearly indicated that the spoilage of pawpaw fruits in the two markets was due to fungal attack.

A total of 24 species of fungi, namely Aspergillus flavus Link, A. fumigatus Fresenius, A. niger (Type 1 and Type 2) Van Tiegh, A. ochraceus K. Wilhelm, A. nidulans Eidam, Aspergillus sp.1, Aspergillus sp.2, Aspergillus sp.3, Curvularia lunata (Wakker) Boedijn, Colletotrichum gloeosporioides Penz & Sacc, C. gossypii Southw., Chaetomium globosum Kunze., Fusarium nivale (Fr.) Sorauer, F. moniliforme J. Shelden, F. oxysporum Schlechtendal, F. fujikuroi Nirenberg, Mucor sp. P. Micheli ex L., Penicillium sp.1 and sp.2 Link, Rhizoctonia solani Khun., Rhizopus stolonifer (Ehrenb.) Vuill., Rhizomucor sp. Lucet & Costantin, Syncephalastrum racemosum Cohn and Trichoderma viride Pers. were found to be associated with the seeds of 14 varieties (CB 1- CB 14) of cotton. Out of these 24 fungal species, nine were found to be pathogenic to cotton. They were Aspergillus flavus, A. niger (Type 1), Aspergillus sp. 1, Colletotrichum gloeosporioides, Curvularia lunata, Fusarium nivale, F. moniliforme, Mucor sp. and Rhizoctonia solani. These pathogenic fungi had remarkable effect on seed germination, vigor index, root-shoot length and mortality of cotton seedlings. The germination percentage of control seeds was 88 but because of the presence of pathogenic fungi the rate showed considerable reduction in all the varieties and it varied from 20 to 82%. Among the nine fungal isolates Rhizoctonia solani showed maximum reduction in seed germination. Aspergillus flavus, Colletotrichum gloeosporioides and Fusarium moniliforme also caused near about 50% reduction in seed germination. Mortality percentage of control seedling were also less (6) whereas, in inoculated seeds it was higher and varied from 7 - 23%. Root- shoot ratio of control seedlings was high but less in inoculated seedlings. The vigor index of control plant was high (1548.8) but less in inoculated plants. The lowest vigor index was noticed for Rhizoctonia solani (202.0) and highest for Aspergillus sp. 1(1213.6). Results indicated that Curvularia lunata and Rhizoctonia solani showed a greater impact in reduction of cotton seed germination and vigor index. Dhaka Univ. J. Biol.

Na atualidade a conservação dos documentos bibliográficos ainda apresenta problemas complexos e diversificados, apesar da maior consciência do tema nos últimos anos. Nesse contexto, a presente pesquisa objetiva conhecer o espectro fúngico de acervos de bibliotecas públicas de referência no município de Fortaleza-CE. Bimestralmente, durante 24 meses, 05 amostras/biblioteca provenientes de livros e/ou documentos históricos escolhidos aleatoriamente foram analisadas, perfazendo no total 180 amostras. As amostras foram colhidas através de swabs estéreis, friccionados por 30 segundos e em seguida transportados em solução salina estéril. Ao chegarem ao laboratório, as amostras foram semeadas em meio de cultura Ágar Batata Dextrose (Himedia®), incubadas por 7 dias (26 – 28 °C) com posterior contagem global e identificação das colônias fúngicas baseada nas análises macro e micromorfológicas. Do total de obras analisadas 86% mostraram positividade para fungos. Nas bibliotecas A, B e C foram contabilizadas 3.612, 4.235 e 2.978 colônias fúngicas, respectivamente e identificados 55 diferentes achados fúngicos (29 gêneros e 26 espécies fúngicas), com destaque para os hialohifomicetos Aspergillus e Penicillium. Os dados revelaram alguns agrupamentos com forte correlação, isto é, quando um dos achados fúngicos ocorre, os demais achados do agrupamento também podem estar presentes nos livros analisados, a saber: Bibliotecas A e B (Aspergillus sp., Aspergillus flavus, Apergillus niger e Penicillium sp.) e Biblioteca C (Aspergillus niger, Trichoderma sp. e Penicillium sp.). A pesquisa permitiu oferecer aos gestores das bibliotecas, elementos para aprofundar seus conhecimentos na área de preservação e conservação de obras literárias de inestimável valor.
