Biofertilizers using living organisms are attractive because of their potential positive impacts on plant growth and minimal environmental bearing. In this study, the effect of plant-growth promoting rhizobacteria (PGPR) and cyanobacteria on wheat was examined in hydroponic growth systems. Calothrix sp. (C) and Anabaena cylindrica (A) were used as...

The LIFE + Integral Carbon project proposed the use of edaphic microalgae for the recovery of the nutrients present in residual effluents of the agro-food industry The fixation of Carbon by algal biomass and recovery of nutrients such as N, P or different trace elements, is key to improving the environmental footprint of agro-industry within the fr...

During the 2009 to 2010 corn-growing (Zea mays L. cv. Alexandria) seasons, severely stunted and yellowing corn plants in several commercial fields at Aldearrubia (Salamanca Province) were observed in western Spain. The disease incidence ranged from 80 to 100%. Early symptoms consisted of severely reduced growth of the plants coupled with extensive...

Food canning preservation makes extensive use of food thermal preservation to eliminate microbial agents, thereby ensuring that products remain microbiologically safe. The aim of the present study is to assess the sterilization treatment of canned foods-beans, chickpeas and lentils-and to determine the D, z and C parameters of their thermal process...

Soil biodisinfection process is based on the biodegradation of incorporated organic amendments to the soil. Soil microorganisms are directly responsible for this decomposition, so the soil biodisinfection process stimulates the soil microbial population activity. These microbial populations increase also produces increased levels of exoenzymes in t...

Damping off is the most common disease caused by edaphic fungi in Spanish crops, among which Rhizoctonia solani AG-4 stands out. In the present work, two possible methods of control were evaluated, incorporation of different doses of organic matter (OM; obtained from strawberry crops) and Pseudomonas fluorescens as a plant growth promoting rhizobac...

The quantitative study of heat treatments for sterilisation uses the Bigelow model to calculate the sterilising value (F). Calculation of F requires the previous determination of parameters D (decimal reduction time at experimental temperature) and Z (thermal-death time parameter), obtained from the thermal-death kinetics. Herein we compare two dif...

Soil and root samples were collected from May to October 2010 from cultivated and wild plants during a survey for hop cyst nematodes. Cyst nematodes were detected in roots of common nettle (Urtica dioica L.) with severe plant yellowing in four natural areas of León and Burgos provinces, Spain, where common nettle is grown in organic farming systems...

The inhibitory effects of the pediocin PA-1 in frankfurters and the Pediococcus acidilactici MCH14 pediocin-producing strain itself in Spanish dry-fermented sausages were evaluated. The experiments were carried out by in situ assays using Listeria monocytogenes and Clostridium perfringens as target bacteria strains. The inhibition of L. monocytogen...
