Arbuscular mycorrhiza-like biotechnological potential of Piriformospora indica, which promotes the growth of Adhatoda vasica Nees
Provedor de dados: 69
Autores: Rai,Mahendra; Varma,Ajit.
We report the growth promoting potential of Piriformospora indica, which is a newly discovered arbuscular mycorrhiza-like fungus. It is a facultative symbiont and unlike arbuscular mycorrhizal fungi, it can be cultured in vitro. Adhatoda vasica is a medicinal plant. Rapid proliferation of roots was recorded in A. vasica withan important root colonization estimated to 95% after 6 months. P. indica improved growth of A. vasica. This association forms a new host-symbiont combination

Manguezais: potencial fonte de microrganismos para o uso como agentes de biocontrole da podridão radicular e promotores de crescimento de plantas em hidroponia.
Provedor de dados: 14
Autores: CORRÊA, E. B.; GALVAO, J. A. H.; BETTIOL, W.
Resumo: Microrganismos residentes de manguezais são adaptados aos baixos teores de oxigênio e flutuações de salinidade, condições encontradas em ambientes hidropônicos. Essa adaptação ecológica torna esses microrganismos em potenciais agentes de controle biológico de podridões radiculares, importantes doenças que incidem sobre cultivos hidropônicos e promotores de crescimento de plantas, pois um dos principais problemas encontrados no biocontrole e na promoção de crescimento em hidroponia é a baixa adaptação dos microrganismos introduzidos. O objetivo do trabalho foi avaliar a capacidade de 28 isolados de microrganismos residentes de manguezais no controle da podridão radicular causada por Pythium aphanidermatum e na promoção de crescimento em pepino...

Live yeasts in the gut: Natural occurrence, dietary introduction, and their effects on fish health and development
Provedor de dados: 5
Autores: Gatesoupe, Joel.
This minireview summarizes the present state of knowledge concerning the importance of yeasts in fish gut. Yeasts have been commonly isolated in the gastrointestinal tract, and high population densities were sometimes noted in healthy fish, but the data were quite variable in terms of colony counts and taxonomical diversity. Rhodotorula sp. seemed relatively frequent in both marine and freshwater fish, and Debaryomyces hansenii has been found to be dominant in rainbow trout. Some other dominant strains have been described, such as Metschnikowia zobelii, Trichosporon cutaneum, and Candida tropicalis in marine fish, and Candida sp., Saccharomyces cerevisiae, and Leucosporidium sp. in rainbow trout. The natural proliferation of yeasts in fish mucus may be...

Acclimatization of Tapeinochilos ananassae plantlets in association with arbuscular mycorrhizal fungi
Provedor de dados: 86
Autores: Oliveira,João Ricardo Gonçalves de; Morais,Thiago Alberto de Lima; Melo,Natoniel Franklin de; Yano‑Melo,Adriana Mayumi.
The objective of this work was to assess the potential of three isolates of arbuscular mycorrhizal fungi to promote growth of micropropagated plantlets of Tapeinochilos ananassae during acclimatization. The experiment was carried out in greenhouse, in a completely randomized block design, with four inoculation treatments: non‑inoculated control and plants inoculated with Glomus etunicatum, Acaulospora longula or Gigaspora albida, with ten replicates. After 90 days, the following parameters were evaluated: survival rate, height, leaf and tiller number, leaf area, fresh and dry biomass, contents of macro‑ and micronutrients in the root and shoot, glomerospore number, and mycorrhizal colonization. The survival percentage was 100%, except for plants inoculated...

ANTIMICROBIAL DRUG USE AND VETERINARY COSTS IN U.S. LIVESTOCK PRODUCTION
Provedor de dados: 31
Autores: Mathews,   Kenneth H., Jr.
Antimicrobial drugs are fed to animals at low levels to treat diseases, to promote growth, and to increase feed efficiency. Incorporating low levels of antimicrobial drugs in livestock feeds has been shown to be a factor stimulating the development of antimicrobial drug resistant bacteria in livestock. Since many of the drugs used to treat livestock are the same as or are related to drugs used in human health care, there is concern that resistant organisms may pass from animals to humans through the handling of animals or food derived from animals. The movement of pathogens from animals to humans, and vice versa, has been documented, but the extent to which it has occurred or could occur is unknown. Although it is estimated that as little as 10 percent of...

Do Antibiotics Reduce Production Risk for U.S. Pork Producers?
Provedor de dados: 31
Autores: Liu,   Xuanli; Miller,   Gay Y.; McNamara,   Paul E.
We combine econometric and financial analyses of the NAHMS 2000 Swine Survey data to examine whether evidence exists for reducing risk by using antibiotics for growth promotion (AGP) in the U.S. swine industry. A stochastic dominance analysis of alternative lengths of time (days) of AGP application reveals that AGP used in the range of 65—75 days is preferred by risk-averse producers. Risk is reduced and profits are increased from use of AGP. The combined impacts of increased average daily gain and decreased variability in pig live weight increase producer profits by $2.99 per pig marketed.

Farm-Level Impacts of Banning Growth- Promoting Antibiotic Use in U.S. Pig Grower/Finisher Operations
Provedor de dados: 31
Autores: Miller,   Gay Y.; Liu,   Xuanli; McNamara,   Paul E.; Bush,   Eric J.
Antibiotics have been used by pig producers for several decades, and are now used routinely. This study documents the current productivity and economic impacts of the use of antibiotics for growth promotion (AGP) by pig grower/finishers at the farm level. We evaluate the impacts of an AGP ban, and use of AGP by all pig grower/finishers for 61S90 days (a more production-efficient level), using data from the National Animal Health Monitoring System Swine 2000 Survey. Findings indicate that pig productivity improves with AGP. Relative to current use, an AGP ban would decrease producer profits by $1,400 per 1,020-head barn, and profits would increase by $1,992 for each grower/finisher barn when AGP is fed for 61 to 90 days. There is increasing concern about...

Effects of Glycyrrhizic Acid on Productive and Immune Parameters of Broilers
Provedor de dados: 89
Autores: Ocampo,CL; Gómez-Verduzco,G; Tapia-Perez,G; Gutierrez,OL; Sumano,LH.
ABSTRACT Considering that glycyrrhizic acid (GRA) has been shown to have in-vitro and in-vivo antiviral activity against a wide range of viruses as well as immunostimulating activity, a trial to evaluate its effects on the performance and the immune response against Newcastle disease of broiler chickens was carried out. The study was performed with one-day-old Ross x Ross broiler chickens. GRA was added to the drinking water throughout the 49-d production cycle at a dose of 0.03%. Sample size of the trial was established in a pilot assay. Results showed that broiler chickens treated with GRA presented better weight gain, final body weight, feed conversion ratio, and lower mortality rate than the non-treated controls. In addition, GRA-treated birds...

Comparison of plant growth-promotion with Pseudomonas aeruginosa and Bacillus subtilis in three vegetables
Provedor de dados: 58
Autores: Adesemoye,A.O.; Obini,M.; Ugoji,E.O.
Our objective was to compare some plant growth promoting rhizobacteria (PGPR) properties of Bacillus subtilis and Pseudomonas aeruginosa as representatives of their two genera. Solanum lycopersicum L. (tomato), Abelmoschus esculentus (okra), and Amaranthus sp. (African spinach) were inoculated with the bacterial cultures. At 60 days after planting, dry biomass for plants treated with B. subtilis and P. aeruginosa increased 31% for tomato, 36% and 29% for okra, and 83% and 40% for African spinach respectively over the non-bacterized control. Considering all the parameters tested, there were similarities but no significant difference at P &lt; 0.05 between the overall performances of the two organisms.

Effects of one haustorium-inducing quinone DMBQ on growth and development of root hemiparasitic plant Monochasma savatieri
Provedor de dados: 65
Autores: Chen,Lanlan; Zhu,Zaibiao; Guo,Qiaosheng; Guo,Jun; Huang,Zhigang; Shi,Yongtao; Wen,Zhencui.
ABSTRACT: Monochasma savatieri Franch. ex Maxim is a perennial, parasitic herb used in traditional Chinese medicine and its wild resources have decreased sharply in recent years due to destructively harvesting and habitat destruction. Haustorium formation is a key event of parasites, but the concentrations of haustorium-inducing factors vary with species and cultivation conditions. In this study, we investigated the effects of the 2,6-dimethoxy-p-benzoquinone (DMBQ) concentration and cultivation density on the growth traits, haustorium formation and biomass of M. savatieri in the absence of a host plant. The results showed that both the DMBQ concentration and cultivation density regulated growth traits, haustorium formation and biomass in M. savatieri. The...
