Título:  Isolation of probiotic bacteria from the hybrid South Americancatfish Pseudoplatystoma reticulatum×Pseudoplatystoma corruscans (Siluriformes: Pimelodidae): A haematological approach.
Ano de publicação:  2016
Fonte/Imprenta:  Aquaculture Reports, Filadélfia, EUA, v. 3, n. , p. 166-171, 2016.
Idioma:  Inglês
Conteúdo:  This study investigated bacterial strains with probiotic potential isolated from the middle portion of healthy hybrid surubim catfish foregut (Pseudoplatystoma reticulatum female× P. corruscans male). Twenty surubims weighing 1.5± 0.3 kg were used for bacterial isolation. In total, 41 strains of bacteria were selected in vitro. Ten strains had inhibition zones >10mm against Aeromonas hydrophila. Five of those strains presented inhibition zones > 9mm against other pathogenic bacteria and reached concentrations greater than 10 CFUmL in tubes containing de Man, Rogosa and Sharpe (MRS) medium. In particular, Weissella cibaria (P36) reached 10 CFUmL in MRS and was able to reduce the pH of the medium to 3.85. In the in vivo intestinal colonization studies, 72 healthy hybrid surubims were fed with a commercial diet supplemented with probiotic W. cibaria for 15 days. Changes in gut community composition were then analyzed, and probiotic profile of W. cibaria was determined molecularly by amplification of rRNA 16S gene was performed using PCR. Compared to control fish, W. cibaria-supplemented fish showed an increase in RBC. These results show the efficacy of our haematological approach to probiotic screening in hybrid sorubim.

Título:  Intensification of Pasture-Based Animal Production System Has Little Short-Term Effect on Soil Carbon Stock in the Southern Brazilian Highland.
Ano de publicação:  2023
Fonte/Imprenta:  Agronomy Journal, Suíça, v. 13, p. 1-9, 2023.
Idioma:  Inglês
Conteúdo:  Pastures are of central importance in food production and provide multiple ecosystem services. The objective of this paper was to determine whether the intensification of pasture-based animal production systems, through practices such as fertilization and improved pasture species, has a higher capacity in the short-term (five years) to sequester carbon in the soil compared to (1) natural grassland without anthropogenic interactions, (2) natural grassland fertilized and overseeded with exotic species, and (3) annual pastures with frequent soil disturbance. The study assessed the organic carbon stock (OCS), total organic carbon (TOC), particle size, porosity, and density at different soil strata, as well as the root system and forage production. Forage dry matter (DM) production varied significantly with means ranging from 6615 to 13,000 kg ha?1 year?1 for natural grassland (NG) and permanent pasture (PP), respectively. Improved natural grassland (ING) and NG presented a higher density and root diameter than PP and annual pasture (AP). Forage systems significantly influenced soil porosity and density, with NG and ING showing lower soil densities and higher soil porosities. The OCS (0?100 cm) was similar between NG (270 Mg ha?1), ING (255 Mg ha?1), PP (274 Mg ha?1), and AP systems (256 Mg ha?1). Over a period of five years, the intensification of pasture-based animal production systems did not have a significant impact on OCS in the soils of a Brazilian subtropical highland.
