Millmerranones A–F: A Meroterpene Cyclic Carbonate and Related Metabolites from the Australian Fungus Aspergillus sp. CMB-MRF324

Fungi have a great diversity and wide distribution at the world. It can be used as the alternative technology for controlling of subterranean termite attack, particularly genus Coptotermes knowned as the wooden destructive organism, by using entomophatogenic fungi. For the purpose of the study, several isolate sources were taken from some locations. The results show that eight numbers of pathogenic fungi was founded by screening and identification of fungi taken from 19 numbers of isolate sources. The pathogenic fungi were Beauveria sp., Penicillium brevicompactum, P. rubrum, Paecilomyces fulvus, Fusarium verticolloides, Pythium sp., and Aspergillus sp. Key words: Jamur entomopatogen, Coptotermes sp.

O controle das podridões das espigas e grãos de milho é realizado principalmente com a aplicação de fungicidas químicos em todas as regiões produtoras do Rio Grande do Sul. O presente trabalho teve como objetivo avaliar a influência da aplicação foliar de fungicidas na incidência de grãos ardidos e de fungos dos gêneros Penicillium sp., Fusarium sp. e Aspergillus sp. em grãos de milho. O experimento foi conduzido na safra agrícola 2014/15, em Cruz Alta, RS. O delineamento experimental utilizado foi o de blocos casualizados (DBC), com 4 tratamentos (3 com aplicação de fungicidas e 1 testemunha sem aplicação) em 4 repetições. Os tratamentos basearam-se nas aplicações dos fungicidas Piraclostrobina + epoxiconazol (380 mL ha-1), Picoxistrobina + ciproconazole (300 mL ha-1) e Azoxistrobina + benzovindiflupir (150 g ha-1). As variáveis analisadas foram: percentagem de grãos ardidos, massa de mil grãos e rendimento de grãos. Houve efeito da aplicação de fungicidas sobre toas as variáveis avaliadas. Os componentes de produção assim como a incidência de grãos ardidos e de fungos fitopatogênicos, em grãos de milho são influenciados pela aplicação via foliar de fungicidas no estádio fenológico V8 da cultura do milho.

<div> Removal of Fe(II) and Mn(II) ions from aqueous solution by fungal biosorbent Aspergillus sp. TU-GM14immobilized on Detarium microcarpum matrix was investigated in this study. Effects of biosorption parameters pH, biosorbent concentration, bead size and equilibrium time on Fe(II) and Mn(II) ions sorption were also determined. Equilibrium was attained within in 3 hours while optimum Fe(II) and Mn(II) ions removal was observed at pH 6, 8 mm bead size, 2 g l-1 spore load respectively. Adsorption capacity was described using Langmuir, Freundlich and BET isotherm models. The experimental data fitted best to the Freundlich model (R2 0.992 and 0.996 for Mn(II) and Fe(II) respectively). Favourable surface sorption process was described by Langmuir isotherm for both metals (Qmax 34 and 14 mg g-1 for Mn(II) and Fe(II) ions) while the BET isotherm constant, B, described high metals sorption beyond the biosorbent surface in a multi-layer sorption process (4.8 and 9.0 for Mn(II) and Fe(II)  respectively). Results of the study showed that Aspergillus sp. TU-GM14 biosorbent can remove large quantities of Fe(II) and Mn(II) ions from solution in both surface and multi-layer sorption process with Detarium microcarpum acting as a cheap immobilization matrix. </div>

Aspergillus Sp

Latar belakang: Pangan merupakan kebutuhan dasar yang paling esensial bagi kelangsungan hidup manusia, salah satunya adalah roti tawar yang sering digunakan sebagai menu sarapan pagi sebagian masyarakat Indonesia. Roti tawar bisa dikonsumsi biasanya tidak dapat tahan lebih dari 7 hari, bahkan ada yang hanya 3 hari. Kontaminasi jamur pada makanan dapat menyebabkan kerusakan, terutama pada saat penyimpanan yang salah satunya Aspergillus sp merupakan spesies yang telah menyebar luas, karena spora jamur yang mudah disebarkan oleh angin, mudah tumbuh pada bahan-bahan pangan. Adanya mikroorganisme yang tumbuh di suatu bahan pangan sangat berpengaruh terhadap penurunan kualitas produknya. Tujuan: Diketahuinya keberadaan jamur Aspergillus sp pada roti tawar yang dijual di Pasar Tradisional. Metode: Penelitian yang digunakan adalah deskriptif, dan sampel berjumlah 16 roti tawar di pasar tradisional dengan teknik samplingnya menggunakan purposive sampling. Waktu penelitian pada bulan Maret-Juni 2018, Metode pemeriksaan dengan cara isolasi jamur Aspergillus sp dengan media Sabaroud Dextrose Agar (+). Hasil: Dari 16 sampel yang diteliti, didapatkan 1 sampel (6,2%) roti tawar yang positif ditemukan jamur Aspergillus sp dan 15 sampel (93,8%) yang negatif. Saran: Diharapkan masyarakat akat sebagai konsumen sebelum membeli roti tawar agar lebih teliti serta memperhatikan kualitas dan kebersihan roti tawar yang akan dikonsumsi serta prosuden roti agar menambah waktu kadaluwarsa pada produk rotinya. Kata kunci : Aspergillus sp, Roti Tawar, Isolasi Jamur
