Microbial additives in the composting process
Provedor de dados: 64
Autores: Ribeiro,Noelly de Queiroz; Souza,Thiago Pereira; Costa,Lívia Martinez Abreu Soares; Castro,Cibelli Paula de; Dias,Eustáquio Souza.
ABSTRACT Composting is the process of natural degradation of organic matter carried out by environmental microorganisms whose metabolic activities cause the mineralization and partial humification of substances in the pile. This compost can be beneficially applied to the soil as organic fertilizer in horticulture and agriculture. The number of studies involving microbial inoculants has been growing, and they aim to improve processes such as composting. However, the behavior of these inoculants and other microorganisms during the composting process have not yet been described. In this context, this work aimed to investigate the effects of using a microbial inoculum that can improve the composting process and to follow the bacterial population dynamics...

Inibição do desenvolvimento fúngico através da utilização de óleos essenciais de condimentos
Provedor de dados: 64
Autores: Pereira,Marcelo Cláudio; Vilela,Georgia Rocha; Costa,Lívia Martinez Abreu Soares; Silva,Reginaldo Ferreira da; Fernandes,Anderson Felicori; Fonseca,Ellen Waleska Nascimento da; Piccoli,Roberta Hilsdorf.
Objetivou-se com este trabalho avaliar os efeitos inibitórios, "in vitro", de óleos essenciais dos condimentos, alecrim (Rosmarinus officinalis L.), cebola (Allium cepa L.), manjericão (Ocimum basilicum L.), menta (Mentha piperita L.) e orégano (Origanum vulgare L.), sobre o desenvolvimento de fungos. Os óleos foram extraídos pela técnica de arraste a vapor e testados nas concentrações de 500; 1000; 1500 e 2000 mg/mL-1. Como culturas de teste foram utilizados os fungos Fusarium sp.; Aspergillus ochraceus Wilhelm.; Aspergillus flavus Link e Aspergillus niger van Tieghem obtidos da micoteca do EcoCentro/EPAMIG em Lavras, MG. O óleo essencial do orégano inibiu o desenvolvimento dos fungos testados em todas as concentrações exceto o fungo A. niger que teve o...

Multivariate analysis of nutritional parameters required for the submerged cultivation of three coprinaceous fungi for biosurfactant production
Provedor de dados: 64
Autores: Martins,Roberta Castro; Bravo,Claudia Eugênia Castro; Vilela,Leonardo de Figueiredo; Costa,Lívia Martinez Abreu Soares; Dias,Eustáquio Souza.
ABSTRACT Biosurfactants are natural hydrocarbon surfactant compounds that decrease surface tension and have a high emulsifying capacity. Biosurfactants are produced through microbial metabolic processes and have several advantages over chemical surfactants, including low toxicity and high biodegradability. Bioremediation offers the possibility of eliminating or transforming various contaminant compounds present in soil and water. Fungi are effective transforming agents due to their ability to degrade a diverse variety of organic substances. Thus, considering the potential of fungi to produce biosurfactants and the importance of these compounds for various industrial processes, the objective of this work was to verify the effects and interactions of...

Potential utilization of spent Agaricus bisporus mushroom substrate for seedling production and organic fertilizer in tomato cultivation
Provedor de dados: 64
Autores: Collela,Carolina Figueiredo; Costa,Lívia Martinez Abreu Soares; Moraes,Tatiana Silveira Junqueira de; Zied,Diego Cunha; Rinker,Danny Lee; Dias,Eustáquio Souza.
ABSTRACT The production of Agaricus bisporus results in significant residual material after cultivation. Due to its physical properties and nutrient content Spent Mushroom Substrate (SMS) has great potential for use in agriculture. Our study evaluated the feasibility of using SMS as an alternative substrate for the production of Paronset® hybrid tomato seedlings and as an organic fertilizer in its production. To conduct the fruit production experiment, the plots consisted of three types of fertilizers (SMS of A. bisporus, NPK and bovine manure) with four replications. The seedlings produced in the SMS presented higher rates of germination time and speeds, and stood out from the other substrates in the evaluation of seedling quality. In the tomato fruit...

Fungal and bacterial population from spent mushroom substrate used to cultivate tomato plants

ABSTRACT The production of tomato seedlings is conducted on commercial substrates with adequate properties for the good formation of the aerial part and root. The Spent Mushroom Substrate, or SMS, presents advantages over commercial substrates regarding the quality of the vegetable seedlings, which may be provided by the presence of a rich microbiota, bringing higher balance and competition with pathogenic microorganisms, in addition to the biological control of pathogens and nematodes. It is important to know the microbiota present in this material and its relation to the plant, in order for this association to occur in the best manner possible. This work had the objective of identifying the microbiota present in the rhizosphere of tomato seedlings...
