Alternatif Media for Fungal Growth Using a Different Source of Carbohidrats

Abstract: Fungi needs utrient, a source of energy and certain environmental conditions in order to growth. PDA was a common medium used to grow fungi in laboratories. The high of instant media PDA encourage researchers to find out alernatif media of the raw materials was easily available and more cheap. This researche determine the fungal growht in alternative media on carbohydrate source of the Canna edulis, Dioscorea aculeata and Maranta arundinacea . This study was an experimental studi using Completely Randomize Design (CDR), two factor. The first factor is a type of fungi: Candida albicans (J1), Aspergillus niger (J2). The second factor was the types of alternative media: the media of Canna edulis (M1), Discorea esculenta (M2) and Maranta arundinaceae L (M3). The collected data is analized by using qualitative descriptive. In this research Candida albicans was tested by spread method at 28 o C for 2 days, Aspergillus niger by agar block method was tested at 30 o c for 7 days. The result show that growth of Candida albicans best on medium Canna edulis with a population of 2,87×10 8 CFU/ml and the size of fungal colony was large white, while the growth of Aspergillus niger best on medium Canna edulis with a diameter about 39,7 mm and heavy sporulation. Both of fungi test showed that almost comparable growth of PDA. Media Canna edulis , Dioscorea aculeata and Maranta arundinacea can be used as alternatives media for fungal growth.

Morfologia de Marantaceae ocorrente no estado de Pernambuco, Brasil

Abstract: The Marantaceae family are typical plants from tropical rain forests These forests are found along the coast and in the countryside of Pemambuco State They are characterized as high altitude forests, under the influenceof Atlantic winds, and are surrounded by the Caatinga This study reviews the complex Marantaceae morphologie and provides identification key for ten genera which occour in the State The resarch was carried out based on recent collections, on consultation to national and international herbaria and on field observation The presence of Calathea Mey, Hylaeanthe Jonker & Jonker, Monotagma Schum, Myrosma L f, Ischinosiphon Koer, Saranthe Eichl, Thalia L, Ctenanthe Eichl, Maranta L, Stromanthe Sond were registered Terminology was based mainly on recent literature, however, some adaptation from other authors were also taken into account Leaf position (homotropic and antitropic), inflorescence arquiteture (congest, lax, bissimetric and monossimetric) and the number of inflorescence are amongst the morphological features used in taxonomic classification

A new “giant” species of Maranta L. (Marantaceae) from the Atlantic Forest of northeastern Brazil

Abstract: A new species of Maranta subg. Maranta , M. gigantea , is described and illustrated. This is known from the submontane Atlantic Forest in the states of Pernambuco and Alagoas (Brazil). Based on the zingiberoid growth form it is morphologically similar to M. anderssoniana and M. zingiberina , differing mainly in the shape of the leaf blade (lanceolate to oblong or ovate respectively vs. narrow-lanceolate) and number of calli in the callose staminode (one prominent callus vs. two prominent calli). It is further differentiated from M. anderssoniana by being larger plants (up to 1.8 m tall vs. up to 1.0 m tall), with a tomentose leaf sheath (vs. sericeous), larger corolla tube length (9−12 mm long vs. 5−6 mm long), asymmetrically elliptical corolla lobes ( vs. asymmetrically oblong) and larger outer staminodes (minor 12−15 × 6.5−8 mm vs. 10−11 × 5.5−6 mm and major 13−16 × 8.5 × 10.5 mm vs. 10−12 × 8−9.2 mm). Due to its narrow distribution, it is classified as critically endangered.

Notes on Singaporean native Zingiberales II: revision of Marantaceae, with a new generic record and notes on naturalised and commonly cultivated exotic species

Abstract: An illustrated revision of Marantaceae in Singapore with an identification key and proposed national IUCN Red List assessments is presented here. In total three genera and four species are considered native to Singapore ( Donax canniformis , Phrynium hirtum , Stachyphrynium parvum , and Stachyphrynium latifolium ) representing 33 % of diversity currently known to occur in Peninsular Malaysia. Although the genus Phrynium Willdenow (1797: 1) was previously reported for Singapore based on the presence of P. villosulum , we show that this species is, contrary to previous accounts, not native but introduced. Newly reported Phrynium hirtum therefore represents a new native generic record for the country. We are changing the status of Schumannianthus benthamianus , previously considered native, to cultivated, as there are no historic or recent collections of this species. Non-native species commonly employed in Singapore streetscapes and parks are also briefly discussed and illustrated in this paper. Actoplanes ridleyi , Donax grandis , Donax parviflora , Maranta tonchat , Phrynium latifolium and Phrynium sumatranum are lectotypified and Maranta arundinacea Blanco (non L.) is neotypified.
