Smallholder farming systems in sub-Saharan Africa have undergone changes in land use, productivity and sustainability. Understanding of the drivers that have led to changes in land use in these systems and factors that influence the systems' sustainability is useful to guide appropriate targeting of intervention strategies for improvement. We studied low input Teso farming systems in eastern Ug...

Crop diversification is essential in lowland rice cropping systems to achieve sustainability, improve soil health, and as a climate-resilient practice reduce greenhouse gas (GHG) emissions. A life cycle assessment (LCA) was conducted for the farms west-coast region of India assess environmental impact rice–rice rice–cowpea systems. The (LCIA) evaluated “cradle-to-gate” perspective. higher energ...

Five common tetracycline resistance genes tet(A), tet(B), tet(M), tet(O) and tet(S) were studied by polymerase chain reaction in 100 bacteria isolated from Iranian fish farms. In the antibiogram test most of the bacteria were either intermediately or completely resistant to tetracycline. Nine isolates out of 46 Aeromonas spp. contained either tet(A/M/S) resistant genes as follows: tet(A) in A. ...

The northern Gulf of Aqaba is an oligotrophic water body hosting valuable coral reefs. In the Gulf, phytoplankton dynamics are driven by an annual cycle of stratification and mixing. Superimposed on that fairly regular pattern was the establishment of a shallow-water fish-farm initiative that increased gradually until its activity was terminated in June 2008. Nutrient, water temperature, irradi...

While the spatial pattern of the highly pathogenic avian influenza H5N1 virus has been studied throughout Southeast Asia, little is known on the spatial risk factors for avian influenza in Africa. In the present paper, we combined serological data from poultry and remotely sensed environmental factors in the Lake Alaotra region of Madagascar to explore for any association between avian influenz...

Over 175 growers in each of six states (Illinois, Indiana, Iowa, Mississippi, Nebraska, and North Carolina) were surveyed by telephone to assess their perceptions of the benefits of utilizing the glyphosate-resistant (GR) crop trait in corn, cotton, and soybean. The survey was also used to determine the weed management challenges growers were facing after using this trait for a minimum of 4 yr....

Functional properties of fermented bran produced by Aspergillus oryzae and Rhizopus sp. in a solid-state fermentation system were determined, with an aim to evaluate their application in food formulation. The defatted rice bran and wheat bran were inoculated with the spores of the cultures and incubated at 30°C for 72 h. Samples were withdrawn at 0, 24, 48 and 72 h. Protein content, protein sol...

Bacillus licheniformis Heshi-B2 was isolated from fermented rice bran in Heshiko, a food produced by aging salted mackerel with fresh rice bran. Here, we report the draft genome sequence of B. licheniformis Heshi-B2, originating from a Heshiko sample from Fukui Prefecture, Japan.
