Logistic regression applied to the incidence of Aspergillus producer of mycotoxin in cocoa beans cultivated in the state of Rondônia, Brazil
The presence of fungi of the genus Aspergillus must be investigated because it is related to the diminishment of quality and consequently to the risk to health of consumers due to the possible production of mycotoxins. In this context, this study was performed with the aim to evaluate the presence of Aspergillus species in cocoa beans produced in the state of Rondônia, Brazil, as well as verify the toxigenic...

Soil microbial, chemical properties and crop productivity as affected by organic manure application in popcorn (Zea mays L. var. everta)
Soil microbial population, dehydrogenase activity and chemical properties of soil under different doses of farmyard manure (FYM), leaf compost and vericopmpost were examined at the research farm of the Indian Agriculture Research Institute (IARI), New Delhi, India during 2008-09 and 2009-10. Results indicated the higher value of microbial population, dehydrogenase activity, organic carbon, available nitrogen (N),...

Arbuscular mycorrhizal fungi (AMF) communities associated with cowpea in two ecological site conditions in Senegal
The objective of this study was to characterize the diversity of arbuscular mycorrhizal fungal (AMF) communities colonizing the roots of Vigna unguiculata (L.) plants cultivated in two different sites in Senegal. Roots of cowpea plants and soil samples were collected from two fields (Ngothie and Diokoul) in the rural community of Dya (Senegal). Microscopic observations of the stained roots indicated a high colonization...

The cultivation of microalgae Cyanobium sp. and Chlorella sp. in different culture media and stirring setting
Microalgae can serve as a source of biocompound with high nutritional and commercial potential, such as fatty acids, vitamins and pigments. The microalgae composition is influenced by the physical and chemical conditions of the culture medium and environment in which they are grown, and the composition can be manipulated to produce specific biomolecules. The lack of stirring or the employment of stirring inefficient in...
