A conscientização ecológica globalizada exige alimentos mais naturais, o que tem levado ao aprimoramento de medidas de controle integrado, através do uso de métodos alternativos para a produção de sementes livres de resíduos tóxicos. Com o objetivo de avaliar a micoflora e a qualidade fisiológica, sementes do algodoeiro (Gossypium hirsutum L.) com e sem línter, cultivares CNPA 7H e Precoce 2 foram tratadas, ou não, com os fungicidas químicos pentacloronitrobenzeno (PCNB), captan, benomyl e tolylfluanid, aplicados puros e também misturados ao extrato de aroeira (Astronium urundeuva L.) e avaliadas quanto à qualidade fisiológica (germinação, índices de velocidade de germinação e de emergência em campo) e à ocorrência de fungos. Utilizou-se o delineamento inteiramente casualizado em esquema fatorial 10x2x2 (tratamentos x cultivares x tipos de sementes), com quatro repetições. Sementes com línter de ambas as cultivares apresentaram menor qualidade fisiológica. O extrato de aroeira puro não controlou os fungos porém, quando associado aos fungicidas, captan, benomyl e tolylfluanid, reduziu a incidência de Aspergillus spp. e Fusarium sp. na cv. Precoce 2. Houve redução na viabilidade e no vigor das sementes deslintadas tratadas com o extrato de aroeira puro ou associado aos fungicidas. A micoflora foi constituída principalmente por: Aspergillus flavus, Aspergillus sp., Fusarium sp. e Rhizopus sp.

Salted fish are fish that are processed through a process of salting and drying. The contamination of fungi in salted fish can be caused by prolonged storage. Storage of salted fish that is too long can cause the growth of various fungi. One of the fungi that often grows in salted fish is the fungus of Aspergillus sp. Some species of the Aspergillus sp fungi can produce aflatoxin, one of which is Aspergillus flavus. This study aims to determine the contamination of toxin-producing fungi in salted fish in the traditional Banjarbaru market in Indonesia. The type of research used is descriptive survey. Samples were taken by purposive sampling taken from 5 salted fish sellers each taken 3 different types of salted fish so that the number of samples was 15. The results were obtained from 15 samples examined, 6 positive samples contaminated with Aspergillus flavus fungi, 8 positive samples contaminated with Aspergillus fungi niger, 5 positive samples contaminated with Monilia sitophila fungi, 6 positive samples contaminated with Rhizopus sp fungi, 6 positive samples contaminated with Penicillium sp fungi, and 1 positive sample contaminated with Mucor sp fungi. Based on the results of the study, samples of salted fish contaminated with Aspergillus sp fungi were 73% (11 samples) and no samples were contaminated with Fusarium sp.

A procura por métodos alternativos para o controle de patógenos em sementes que não afetam o meio ambiente vem ganhando uma atenção mundial. Dentre os métodos alternativos temos a termoterapia, que se baseia no efeito das temperaturas elevadas sobre a atividade celular dos patógenos. O trabalho objetivou-se avaliar a eficiência da termoterapia via calor úmido sobre a micoflora fúngica e na qualidade fisiológica em sementes de aroeira-do-sertão (Myracrodruon urundeuva Fr. Allemão). O teste de sanidade consistiu de 100 sementes por tratamento, sendo distribuídas em cinco repetições de vinte sementes. As sementes foram imersas durante 5, 10 e 15 minutos em água destilada esterilizada aquecida nas temperaturas de 40, 50 e 60 °C. Utilizou-se no teste de germinação 100 sementes, sendo quatro repetições de 25 sementes por tratamento. A imersão das sementes em água quente a 40, 50 e 60 °C durante 5, 10 e 15 minutos, foi suficiente para impedir o aumento da incidência de Aspergillus sp., Rhizopus sp., Fusarium sp., Penicillium sp. e Botrytis sp. As temperaturas de 50 e 60 °C por 10 e 15 minutos de imersão foram eficientes na redução de Aspergillus niger. A termoterapia proporcionou aumento na germinação das sementes de M. urundeuva.

<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>

No Brasil, a adição de fitases em ração animal tem sido usada para minimizar os efeitos antinutricionais doácido fítico, além de diminuir os impactos ambientais e a adição de fósforo na ração. Este estudo teve comoobjetivo avaliar a produção de fitases e caracterizar, bioquimicamente, as enzimas produzidas por fungosisolados na região do Alto Paranaíba, no estado de Minas Gerais. Foram utilizados quatro isolados de Rhizopussp., obtidos a partir de amostras de amendoim e dois isolados de Aspergillus niger, um isolado de Trichodermasp., um isolado de Xylaria sp. e um isolado de Fusarium sp., obtidos no banco de culturas do laboratório deMicrobiologia da Universidade Federal de Viçosa (UFV), campus Rio Paranaíba. Os isolados de Rhizopus sp.,Thichoderma sp. e Fusarium sp. não apresentaram atividade enzimática significativa, enquanto os isolados deA. niger e Xylaria sp., por apresentarem atividade enzimática significativa, foram selecionados para a etapa decaracterização bioquímica. Na fermentação no estado líquido, um dos isolados de A. niger apresentou maioratividade enzimática (0,89 U.mL-1) em 216 h, enquanto na fermentação no estado sólido, o isolado de Xylariasp. apresentou maior atividade enzimática (2,88 U.g-1) em 264 h. A fitase de Xylaria sp. apresentou pH ótimoigual a 2,5, temperatura ótima de 45 °C e manteve 91% de atividade residual, após ser mantida a 50 °C durante15 min., enquanto a fitase de A. niger apresentou pH ótimo igual a 3, temperatura ótima de 60 °C e manteve68% de atividade residual, após ser mantida a 70 °C durante 15 min. Os resultados indicam que as enzimasapresentam potencial para aplicação industrial.
