Ecotoxicology of Pig Slaughterhouse Waste Using Lactuca sativa L., Raphanus sativus L., and Oryza sativa L.

Maiara Figueiredo Ramires ORCID logo , Eduardo Lorensi de Souza, Daniel Erison Fontanive, Renan Bianchetto, Ângelo Munaretto Krynski, Júlio Cesar Grasel Cezimbra, [...]


ABSTRACT Pork is the most consumed animal protein around the world. The production levels are significant, which results in the generation of large amounts of slaughter waste. Such waste is often disposed of improperly in agricultural areas, causing environmental imbalance by the contamination of soil and water sources with metals and pathogenic organisms. This study evaluates the phytotoxic effects of pig slaughterhouse waste in natura and after stabilization processes on lettuce (Lactuca sativa Linnaeus, 1753), radish (Raphanus sativus Linnaeus, 1753), […]

Isolation, Characterization and Symbiotic Efficiency of Nitrogen-Fixing and Heavy Metal-Tolerant Bacteria from a Coalmine Wasteland

Paulo Ademar Avelar Ferreira, Sabrina de Fatima Barbosa Dahmer, Tais Backes, Andressa de Oliveira Silveira, Rodrigo Josemar Seminoti Jacques, Mohsin Zafar, [...]


ABSTRACT: Areas affected by coal mining can be recovered by revegetation with leguminous plants associated with nitrogen-fixing bacteria. This study addressed the isolation and characterization of native nitrogen-fixing bacteria from coalmine wasteland under different vegetation restoration approaches using Macroptilium atropurpureum (DC) Urb and Vicia sativa L. as trap plants. The bacteria were characterized and identified on the basis of 16S rRNA sequences. Additionally, nitrogen-fixing strains were characterized for tolerance to high heavy metal and low pH levels, as well as […]

Cattle Manure Bioconversion Effect on the Availability of Nitrogen, Phosphorus, and Potassium in Soil

Daniel Pazzini Eckhardt, Marciel Redin, Natielo Almeida Santana, Lessandro De Conti, Jorge Dominguez, Rodrigo Josemar Seminoti Jacques, [...]


ABSTRACT The efficiency index (EI) refers to the ratio of nutrients mineralized/made available in the soil to the total amount of nutrients added by organic fertilizer. Therefore, understanding the EI is essential for recommendation of organic fertilization. The aim of this study was to evaluate the availability through mineralization and the efficiency index of nitrogen (N), phosphorus (P), and potassium (K) in organic fertilizers produced from cattle manure. The following treatments were evaluated in an incubation experiment under controlled conditions: […]

Soil Biological, Chemical, and Physical Properties After a Wildfire Event in a Eucalyptus Forest in the Pampa Biome

Natielo Almeida Santana, Cedinara Arruda Santana Morales, Diego Armando Amaro da Silva, Zaida Inês Antoniolli, Rodrigo Josemar Seminoti Jacques


ABSTRACT Wildfire events cause considerable environmental disturbance but few studies have examined changes in soil properties due to fire. This study aimed to assess the effect of a wildfire event on chemical, physical, and biological properties of the soil in a eucalyptus forest in the Pampa biome. Part of a seven-year-old eucalyptus forest was affected by a wildfire event that lasted for two days. Soil and plant litter sampling was performed in three areas: in the forest that was not […]

Microbiological Indicators of Pasture Soil with Successive Applications of Pig Slurry

Danni Maisa da Silva, Zaida Inês Antoniolli, Rodrigo Josemar Seminoti Jacques, Andressa de Oliveira Silveira, Diego Armando Amaro da Silva, Magnus Maurício Rache, [...]


ABSTRACT Pig slurry use as soil fertilizer is a common practice in southern Brazil. In spite of the benefits of reusing waste, this practice poses serious environmental risks. Microbiological indicators of soil quality are very sensitive and allow soil environment conditions to be monitored. The aim of this study was to evaluate the microbiological quality of pasture soils with different histories of successive use of pig slurry. Determinations were made of C content in the microbial biomass, soil microbial respiration, […]

Epigeic fauna in production systems of Nicotiana tabacum L.

Marta Sandra Drescher, Ana Paula Moreira Rovedder, Zaida Inês Antoniolli, Flávio Luiz Foletto Eltz, Gerson Laerson Drescher


The state of Rio Grande do Sul is an important tobacco producer. The crop is produced in three management systems: conventional tillage (CT), minimum tillage (MT) and no tillage (NT). To assess the impact of these systems on the soil fauna population, the epigeic fauna was sampled. Aside from the three cited systems, an area in conversion from tobacco to grape (TGr) and an area of native forest (NF) were evaluated. Ten Provid traps per area were used for sampling. […]

Ribosomal dna characterization of Scleroderma UFSMSc1 of Eucalyptus grandis W. Hill ex-maiden

Manoeli Lupatini, Andrea Hentz de Mello, Zaida Inês Antoniolli


The ribossomal deoxyribonucleic acid (rDNA) represents an important tool in the characterization of fungi polymorphism. There are many copies of rDNA arranged in non encoded spaces. These copies are highly preserved in fungus species. The purpose of this study was to investigate the Internal Transcribed Spacer (ITS) region and to analyze the differences in the sequence polymorphism of the ITS region in the fungus Scleroderma UFSMSc1 with sequences of Scleroderma and Pisolithus isolates from the GenBank database. The DNA of […]
