“…Following the morphological analyses, L. subdecastes should be placed in L. decastes complex [ 55 , 56 ]; L. decastes , L. shimeji , and L. loricatum are similar to L. subdecastes in their appearance. However, the specimens found in Poland of L. decastes differ from L. subdecastes in their broader pileus, slightly longer stipe, lower altitude of distribution areas, and slightly larger basidiospores 5.0–7.0 μm [ 52 , 57 ].…”

The lyophylloid agarics are a group of ecologically highly diversified macrofungi, some of which are very popular edible mushrooms. However, we know little about lyophylloid species diversity in China. In this study, we described four new species from China: Lyophyllum atrofuscum, L. subalpinarum, L. subdecastes, and Ossicaulis sichuanensis. We conducted molecular phylogenetic analyses of Lyophyllaceae based on the nuclear ribosomal RNA gene (nLSU) and the internal transcribed spacer regions (ITS). Phylogenetic analyses by the maximum likelihood method and Bayesian inference showed that the four new species are unique monophyletic species. A key to the species of Lyophyllum from China and a key to Ossicaulis worldwide were given.

“…Pada media PDA, kapang dapat tumbuh dengan baik karena PDA ini mempunyai beberapa nutrisi essensial untuk pertumbuhan kapang (Westphal et al, 2021). Menurut Gabriel et al (2018), kapang tumbuh dengan baik dan menyebar ke setiap sudut petri untuk memaksimalkan pencarian nutrisi pada media. Kapang Hypocreales sp.…”

Feed quality is a very important factor in shrimp farming because it will affect shrimp growth, water quality and even the emergence of pathogenic bacteria. High quality feed can be well digested by shrimp so that it can improve the growth and do not leave plenty of residue. Mold is capable of producing cellulase which can be used to improve feed quality by shortening carbohydrate chains. This paper will discuss the application of endophytic molds to simplify cellulose in shrimp feed. Mold isolates were collected from mangrove ecosystems in North Sulawesi. The media used for culturing mold are potato dextrose agar (PDA) and potato dextrose broth (PDB). Fermentation test was conducted using the fungal isolates; Hypocreales sp. and Diaporthe stewartii and consortia and controls. Fermentation results were checked by TLC and Fehling's test to determine the composition of the compounds and the presence of reducing sugar either mono or di-saccharide. Fermented shrimp feed shows differences in texture and color. Fermented feed extract with Hypocreales sp. 2.69 g (3.36%), Diaporthe stewartii 4.9 g (6.13%), and consortium 3.75 g (4.69%). TLC results neither under UV light nor visualization of vanillin sulfate did not show any differences of compounds in the control and the fermented feed. The results of the Fehling test showed that the mold was able to degrade cellulose that can be utilized to increase the shirmp feed quality. Kualitas pakan merupakan faktor yang sangat berpengaruh dalam budidaya udang karena akan mempengaruhi pertyumbuhan udang, kualitas air bahkan timbulnya bakteri pathogen. Pakan yang baik mudah dicerna oleh udang sehingga dapat meningkatkan pertumbuhan secara maksimal dan tidak terlalu banyak meninggalkan residu. Kapang mampu memproduksi selulase yang dapat digunakan untuk meningkatkan kualitas pakan dengan memperpendek rantai karbohidrat. Tulisan ini akan membahas aplikasi kapang endofit untuk menyederhanakan selulosa pada pakan udang. Isolat kapang dikoleksi dari ekosistem mangrove di Sulaweri Utara. Media yang digunakan untuk mengkultur kapang adalah potato dextrose agar (PDA) dan potato dextrose broth (PDB). Uji fermentasi dengan kapang Hypocreales sp. dan Diaporthe stewartii dan konsorsium serta kontrol. Hasil fermentasi dicek dengan TLC dan uji Fehling untuk mengetahui komposisi senyawa dan keberadaan mono-karbohidrat. Pakan udang yang difermentasi menunjukkan perbedaan tekstur dan warna. Ekstrak pakan fermentasi dengan Hypocreales sp. sebesar 2,69 g (3,36%), Diaporthe stewartii sebesar 4,9 g (6,13%), dan konsorsium sebesar 3,75 g (4,69%). Hasil TLC dan visualisasi vanillin sulfat tidak menunjukkan perbedaan jenis senyawa pada pakan kontrol dan pakan terfermentasi. Hasil uji Fehling menunjukkan bahwa kapang mampu mendegradasi selulosa yang dapat digunakan untuk meningkatkan kualitas pakan udang.

Nanofibers containing Volariella volvacea spores were prepared by electrospinning technique. It has been one of the promising and alternative techniques in immobilizing microorganism cells including bacteria, virus and fungi through entrapment process. The nanosize electrospun nanofibers exhibit outstanding properties including high porosity and reusability which make them an ideal candidates for various types of potential application especially in bioprocess development. In the present study, the spores of Volvariella volvacea were suspended in a series of polymer solutions (poly (vinyl alcohol) and polyvinyl pyrrolidone) and subjected to an electrostatic field supplied by the power voltage. The viability of the entrapped spores was estimated through microorganism cells test by culturing the obtained nanofiber mats on potato dextrose agar (PDA) and studying their growth rate. The Volvariella volvacea spores electrospun in nanofibers remained viable for 12 days at room temperature (30˚C) with PVP electrospun nanofiber chosen as the best carrier matrix for entrapment of Volvariella volvacea. The present result demonstrated that electrospinning process possess high potential in entrapping and immobilizing of microorganism cells.
