Antifungal activity of the isolated from caatinga actinobacteria in control of Pythium aphanidermatum. Repositório Alice
PAMPLONA, R. de C. de A.; VILELA, E. S. D.; PANSA, C. C.; CASTELIANI, A. G. B.; MOITINHO, M. A.; MELO, I. S. de.
The Caatinga is a biome located in a semiarid region of northeastern Brazil. It consists of various ecosystems, presented a unique environmental system of this country. Because it is an environment with unique characteristics, recent studies have revealed the private wealth of this biome in terms of microbial biodiversity. Microorganisms found in this habitat may present specific mechanisms to ensure their survival in this environment that provides extreme conditions, such as temperature changes, intense solar radiation and hydrous stress. Because of these different mechanisms used by different microorganisms, becomes an enabling environment to search for new enzymes and bioactive substances produced by these organisms can present different...

Change in enzymatic activity of microbial communities on the seasonal differences in soils the of biomes caatinga and atlantic forest. Repositório Alice
BONONI, L.; VASCONCELLOS, R. L. F.; TAKETANI, R. G.; VILELA, E. S. D.; MOITINHO, M. A.; MELO, I. S. de.
Abstract: The average global temperature has increased and will continue increasing, with forecast of up to 5.8° C by the end of this century as a result of the increase in the concentration of greenhouse gases in the atmosphere. Due to these increased temperature, some biomes may introduce features of arid and semi-arid environments in the coming years. The patterns of water availability in the soil can select groups of microorganisms with physiological strategies to tolerate these seasonal changes. Nutrient availability for plants becomes limited when the aqueous part of the soil is low in the dry period. On the other hand, in irrigated soils the concentration of nutrients available associated with mineralization increases rapidly. Environmental...

Co-occurrence patterns of litter decomposing communities in mangroves indicate a robust community resistant to disturbances. Repositório Alice
TAKETANI, R. G.; MOITINHO, M. A.; MAUCHLINE, T.; MELO, I. S. de.
Abstract: Background. Mangroves are important coastal ecosystems known for high photosynthetic productivity and the ability to support marine food chains through supply of dissolved carbon or particular organic matter. Most of the carbon found in mangroves is produced by its vegetation and is decomposed in root associated sediment. This process involves a tight interaction between microbial populations, litter chemical composition, and environmental parameters. Here, we study the complex interactions found during litter decomposition in mangroves by applying network analysis to metagenomic data.

Dynamic of microbial community during distinct stages of organic matter decomposition in sediments from mangroves of São Paulo state. Repositório Alice
MOITINHO, M. A.; YOSHIURA, C. A.; BONONI, L.; VASCONCELLOS, R. L. F.; MELO, I. S. de; TAKETANI, R. G..
Abstract: Mangroves are ecosystems located at coastline areas in tropical and subtropical conditions that are under tide influences. They are recognized as productive regions and have a high export of organic matter (OM) for the adjacent coastal waters. Bacterial communities present in these environments perform primordial functions on the cycling of nutrients and thereby on maintaining your important processes. Therefore, the purpose of this study was to assess the dynamics and phylogenetic diversity of the bacterial community in threes of São Paulo mangroves, during different stages of decomposition plant material. At the same time, the intention was to correlate this event with the emission of greenhouse gases (GHG). Microcosms were constructed with...

Metatranscriptomic and Metagenomic insights into the litter decomposition in mangroves. Repositório Alice
TAKETANI, R. G.; MOITINHO, M. A.; MELO, I. S. de.
Mangroves are costal ecosystems known for its important role as sink and source of organic matter. This ecosystem covers most of the tropical and subtropical shores. A major portion of the organic matter that is produced by the mangrove vegetation is exported to nearby marine ecosystems. Therefore, this study was designed to shed light over the process of litter decomposition by using high throughput sequencing of the mRNA and DNA present in decaying mangrove leaves. With this purpose, litter bags contatining leaves of Laguncularia racemosa, Avicennia schaueriana and Rhizophora mangle were left on the mangrove sediment for 60 days. This experiment was conducted in three different mangroves in different locations. These material was had its total DNA and...

Salinity gradient as a selective pressure in bacteria diversity from Laguncularia racemosa phylloplane. Repositório Alice
MOITINHO, M. A.; CHIARAMONTE, J. B.; SOLANO, J. H.; BONONI, L.; MELO, I. S. de; TAKETANI, R. G..
Mangroves are dynamic and unique ecosystems which provide important ecological services to coastal areas. The phylloplane is one of the greatest microbial hosts and most of their microorganisms are uncultivated, thus having the potential to house novel bacteria species. Bacterial community structure of L. racemosa phylloplane, a well-adapted mangrove species with salt exudation at foliar levels, was accessed through 16S rRNA amplicon sequencing. Sampling was performed at Cananéia mangrove in São Paulo state, Brazil in three different sites across a transect from the upland to the seashore. There was significant effect of the sites in the bacterial microbial community along the transect. Higher diversity was observed in intermediary locations between the...
