“…The prevalent isolates from estuarine, littoral and deep‐water marine sediments of Florida and the Bahamas have been mostly oxidative yeasts, including Rhodotorula and Cryptococcus , typical of sea water 50, 84, 149. A new ascosporogenous yeast, Lachancea meyersii sp.…”

“…Yeast populations from conch and spiny lobster on the Bahama Islands were studied by Voltz et al 149 They isolated fewer types of yeast from the animals than from marine sand and sediment of the same habitat, and assumed that the isolates were probably ingested during feeding and did not seem to cause stress to their hosts. The commercially raised brine shrimp, Artemia salina , was parasitized by Metschnikowia bicuspidate var.…”

Yeasts are ubiquitous in their distribution and populations mainly depend on the type and concentration of organic materials. The distribution of species, as well as their numbers and metabolic characteristics were found to be governed by existing environmental conditions. Marine yeasts were first discovered from the Atlantic Ocean and following this discovery, yeasts were isolated from different sources, viz. seawater, marine deposits, seaweeds, fish, marine mammals and sea birds. Nearshore environments are usually inhabited by tens to thousands of cells per litre of water, whereas low organic surface to deep-sea oceanic regions contain 10 or fewer cells/litre. Aerobic forms are found more in clean waters and fermentative forms in polluted waters. Yeasts are more abundant in silty muds than in sandy sediments. The isolation frequency of yeasts fell as the depth of the sampling site is increased. Major genera isolated in this study were Candida, Cryptococcus, Debaryomyces and Rhodotorula. For biomass estimation ergosterol method was used. Classification and identification of yeasts were performed using different criteria, i.e. morphology, sexual reproduction and physiological/biochemical characteristics. Fatty acid profiling or molecular sequencing of the IGS and ITS regions and 28S gene rDNA ensured accurate identification.

“…There have been few studies of the yeast communities of coastal marine ecosystems, and most of these were done in North America (Fell et al, 1960;Fell and van Uden, 1963;Hagler et al, 1982;Lazarus and Korburger, 1974;Meyers and Ahearn, 1974;Meyers et al, 1971;Suehiro, 1963;Volz et al, 1974). Yeasts of coastal sediment habitats may be involved in decomposition, nutrient cycling and in the biotransformation of petroleum, xenobionts and other complex compounds (Ahearn and Meyers, 1972;MacGillivray and Shiaris, 1993;Meyers and Ahearn, 1974).…”

“…Kurtzman e Fell (1998) referem a baixa ocorrência e diversidade de espécies de leveduras em águas de ambiente hipersalino. As populações de leveduras são mais escassas na água do mar do que em água doce, e diminuem com a profundidade e a distância da superfície (VOLZ; JERGER; WORZBURGER, 1974). Neste trabalho a baixa frequência de espécies de leveduras ascomicéticas e a prevalência de espécies de Candida estão de acordo com os achados de (SOARES et al, 1997) em uma região costeira do Rio de Janeiro.…”

RESUMOLeveduras isoladas de sedimento do manguezal Barra das Jangadas, Jaboatão dos Guararapes, Pernambuco, Brasil.Os manguezais constituem ecossistemas de transição entre os ambientes terrestre e marinho caracterizados por propriedades físico-químicas únicas, influenciando a biota local. Para se obter espécies que poderão ser utilizadas em processos biotecnológicos foram isoladas e identificadas leveduras desse ecossistema. Amostras de sedimento foram coletadas nos meses de março e abril2004 e outubro/2005 (período de estiagem), junho e julho/2004 e julho/2005 (período chuvoso). Utilizou-se 25g de cada amostra do sedimento suspensa em 225mL de água destilada esterilizada; desta suspensão 10mL foi adicionada a 990mL de água destilada esterilizada, da qual 1mL foi espalhado na superfície do meio Sabouraud acrescido de extrato de levedura e cloranfenicol, contidos em placas de Petri em triplicata. As placas foram armazenadas a TA. Foram isoladas 32 espécies de leveduras distribuídas nos gêneros; Candida (25), Trichosporon (3), Kluyveromyces (2), Rhodotorula (1), Debaryomyces (1).Palavras chave: manguezal; sedimento; leveduras. ABSTRACTThe mangrove constitute ecosystem of transition between the land and aquatic environments characterized by physical and chemical unique properties influencing the local biotic. To get species that can be used in a biotechnology process were isolated and identified yeasts of this ecosystem. Samples of sediments were collected in the months of March and April/2004 and October/2005 (dry period), June and July/2004 and July/2005 (rainy period). 25g were used in each one of the sediments samples suspend in 225mL of sterilized water; 10mL of this suspended were added at 990mL of sterilized water, and from this 1mL was scattered by the surface of the Sabouraud added by extract of yeast and chloranfenicol, in the dishes of Petri. The plates were incubated temperature at 28°C. Were isolated 32 species of yeasts can be distributed in these kinds: Candida (25) Trichosporon (3), Kluyveromyces (2), Rhodotorula (1), Debaryomyces (1).
