Bioprospection of freshwater microalgae from Bonito, MS, Brazil

The great biodiversity of the Serra da Bodoquena is the result of years of biological evolution. A complex combination of natural factors allows aquatic plants, fish and invertebrates to coexist in absolutely crystalline water springs. Together, organisms form an intricate web of life, connecting a single-celled microalga with large river predators. For better knowledge of the biodiversity of microalgae, an important...

Effect of traditional and modified grain-soaking methods on physicochemical characteristics and consumers’ acceptability of sorghum ogi

The influence of traditional and modified soaking methods and varietal difference of sorghum [Sorghum bicolor (Linn.) Moench] grains on the physicochemical properties and consumers’ acceptability of ogi was investigated. Three sorghum varieties (SAMSORG-14, SAMSORG-41 and SAMSORG-42) were used for the study, and each was subjected to three grain-soaking methods (SGW-72, PBW-24 and IBG5-24) after which ogi was...

Production and marketing of rice in Kenya: Challenges and opportunities

Rice farming remains an important concern in Kenya due to its positive impact on increasing household food security, raising farmer’s income as well as reducing risks in the years of poor weather conditions. Currently, the demand for rice in Kenya outstrips its production, a gap that is filled through imports. Thus, increasing rice production and productivity in Kenya requires a number of measures to be put in...

Impact of the storage conditions and duration on some nutritional parameters of three flours of mass consumption in Cameroon

Wheat, maize and cassava flours are of mass consumption in Cameroonian households. Depending on the frequency of consumption and the size of households, these flours can take several months before complete exhaustion. The present work assessed the impact of three common storage conditions (aerobic, partial aerobic and anaerobic) on the evolution of some nutritional parameters of these flours. The results showed that...

Preparation and analysis of goat milk mozzarella cheese containing soluble fiber from Acacia senegal var. kerensis

Mozzarella cheese is one of the preferred ingredients for use in pizza. Goat milk is a good source of protein and calcium, possessing unique characteristics with a high proportion of small milk fat globules that contain a higher concentration of short chain, medium chain and polyunsaturated fatty acids than cow’s milk. Its use in mozzarella cheese can therefore impart significant health benefits to consumers....

Food insecurity in the green famine belt of Ethiopia: Extent and severity in Belo-jiganfoy District, Benishangul-gumuz region

The green famine belt of Ethiopia is customarily viewed as food secure area only due to relatively adequate rainfall and green vegetation cover. In contrast, this paper argues and shows that the food insecurity condition termed as “green famine” has always existed in the belt. Accordingly, the paper examined the extent and severity of food insecurity based on a cross-sectional survey of 220 households in...

Does gender matter in effective management of plant disease epidemics? Insights from a survey among rural banana farming households in Uganda

Crop diseases significantly suppress plant yields and in extreme cases wipe out entire crop species threatening food security and eroding rural livelihoods. It is therefore critical to estimate the extent to which shocks like disease epidemics can affect food availability and the capacity of smallholder farmers to mitigate and reverse the effects of such shocks. This study utilizes sex-disaggregated data from 341...
