Phosphorus (P) is the major essential macronutrient of plants. But its availability in Indian soil is relatively low due to high rate of P fixation. The use of phosphate solubilizing microorganism (PSM) to solubilize the fixed form of P is economically reasonable and ecologically safe as compared to chemical phosphatic fertilizers. Fungi have been reported to possess greater ability to solubilize insoluble phosphate... Read more.

Campylobacters are very important foodborne pathogens that raise the interest of food processors, researchers, as well as consumers and all stakeholders. Their contaminations can result in life threatening disorders, potentially leading to chronic sequelae such as Reiter’s and Guillain-Barré syndromes or Crohn’s Disease. Poultry has been identified as the main and most common reservoirs for... Read more.

In Nigeria, there is paucity of information on the epidemiology of infections due to Chikungunya virus (CHIKV) especially among patients with febrile illness. Cases of febrile illness are usually associated with malaria and typhoid fever without considering the possibility of viral aetiology. This study was designed to determine the prevalence and identify other epidemiological parameters of CHIKV infections among... Read more.

Proteolytic enzymes are metabolites that can be produced by microbial sources and develop important functions in food industry as in cheese manufacturing. However, it is necessary to ensure the final product safety by testing toxins production by microorganisms. As a result of this, the aim of this study was to investigate the production of proteases by Aspergillus flavo furcatis DPUA 1608 in submerged and solid state... Read more.
