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...

Draft genome sequence of plant growth-promoting drought-tolerant Bacillus sp. strain CMAA 1363 isolated from the Brazilian Caatinga biome. Repositório Alice
KAVAMURA, V. N.; SANTOS, S. N.; TAKETANI, R. G.; VASCONCELLOS, R. L. F.; MELO, I. S. de.
The strain of Bacillus sp. CMAA 1363 was isolated from the Brazilian Caatinga biome and showed plant growth-promoting traits and ability to promote maize growth under drought stress. Sequencing revealed genes involved in stress response and plant growth promotion. These genomic features might aid in the protection of plants against the negative effects imposed by drought.

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...

SILVA, F. S. P. da; SOUZA, D. T.; ZUCCHI, T. D.; VASCONCELLOS, R. L. F.; PANSA, C. C.; MORAES, F. C.; MELO, I. S. de.
A novel gram-positive, aerobic, actinobacterial strain, CMAA 1362T, was isolated from marine sponge Scopalina ruetzleri collected in the São Pedro and São Paulo Archipelago. São Pedro and São Paulo Archipelago (former Saint Paul`s Rocks) liaison the São Paulo Fracture Zone, 1,010 km northeast from Brazilian mainland in the Equatorial Atlantic Ocean, Brazil (0°54?57?N; 29°20\'41\"W). It is one of the smallest and most isolated archipelagos in the world, with 420 m across, 18 m height and 1.7 ha. The archipelago is under the influence of the South Equatorial Current, driving surface water from east to west, and the Equatorial Undercurrent, moving water in the opposite direction between 40-150 m depth. Tissue samples of the marine sponge Scopalina ruetzleri...

Pseudomonas aestus nov. sp. from mangrove sediments: a gluconic acid and betaine producer. Repositório Alice
VASCONCELLOS, R. L. F.; ZUCCHI, T.; SILVA, F. S. P. da; SANTOS, S. N.; SOUZA, D. T.; MELO, I. S. de.
Because of the environmental problems from global warming, the search for microorganisms that promote plant growth under drought and salt conditions is becoming inevitable. A Gram negative bacterium, resistant to 1M salt, gluconic acid and betaine producer and plant growth promoter was isolated from the Brazilian coast mangroves. By the phylogenetic analysis of the 16S rRNA, the strain was included in the taxonomic group of Pseudomonas. Hybridization with type strains and biochemical tests indicate that Pseudomonas strain is a new species. Thus, the name Pseudomonas aestus nov. sp. was proposed and the strain deposited in Embrapa Environment culture collection with the access code CMAA1215.

Rhizosphere microbial community manipulation under salted soil by the inoculation of Pseudomonas sp CMAA 1215 in Zea mays. Repositório Alice
VASCONCELLOS, R. L. F.; ROMAGNOLI, E. M.; TAKETANI, R. G.; MELO, I. S. de.
Soil salinity reduces the soil organic carbon stock, the microbial biomass and activity and modifies the biogeochemical cycle and the microbial diversity. Osmotic stress caused by ethylene on plants can be reduced using 1-aminocyclopropane-1-carboxylate (ACC) deaminase plant growth promoting bacteria (PGPR) producers. Studies of PGPR and commercially strains are based only on the growth of the plant without concern about modification of the microbial community. This scenario has shown an increasing need to study the ecological functions of bacterial community on salted soil and to develop new technologies to reduce environmental impacts and waste of natural resources. Our aim was to study the influence of the Pseudomonas sp. CMAA1215, a known ACC deaminase...

Soil health: looking for suitable indicators. What should be considered to assess the effects of use and management on soil health? Repositório Alice
CARDOSO, E. J. B. N.; VASCONCELLOS, R. L. F.; BINI, D.; MIYAUCHI, M. Y. H.; SANTOS, C. A. dos; ALVES, P. R. L.; PAULA, A. M. de; NAKATANI, A. S.; PEREIRA, J. de M.; NOGUEIRA, M. A..
Soil Health refers to the ecological equilibrium and the functionality of a soil and its capacity to maintain a well balanced ecosystem with high biodiversity above and below surface, and productivity. To understand and use soil health as a tool for sustainability, physical, chemical, and biological properties must be employed to verify which respond to the soil use and management within a desired timescale. Attributes with a rapid response to natural or anthropogenic actions are considered good indicators of soil health. Among the physical indicators, soil texture, aggregation, moisture, porosity, and bulk density have been used, while among chemical indicators total C and N, mineral nutrients, organic matter, cation exchange capacity, among others are...
