Several etiological and epidemiological studies have been undertaken to determine the disease causal agent and the mechanism of spread of Cassava brown streak disease (CBSD). Until recently, two distinct potyviruses have been reported to cause the disease. These are Cassava brown streak virus (originated in Tanzania but most widely spread) and Ugandan Cassava brown streak virus (reported in Uga...
Indigenous beers (chicha) are part of the indigenous culture in Ecuador. The fermentation process of these beers probably relies on microorganisms from fermented substrates, environment and human microbiota. We analyzed the microbiota of artisanal beers (including a type of beer produced after chewing boiled cassava) using bacterial culture and 16S ribosomal RNA (rRNA) gene-based tag-encoded FL...
The origin of root softening during cassava retting was investigated in a natural retting and in a sterile fermentation. Softening only occurred in the natural retting. Although high activities of endogenous pectin methyl esterase were found in cassava extracts from both fermentations, the depolymerizing enzymes polygalacturonase, active at low pH, and pectate lyase were only found in the non-s...
The aim of this study was to determine and compare the melting (Tm), glass transition (Tg) and mechanical relaxation (Tα) temperatures of a new waxy cassava starch. Thermal transitions measurements were obtained by Differential Scanning Calorimetry (DSC) and Dynamical Mechanical Thermal Analysis (DMTA). The experimental data showed a high correlation between water volume fraction and melting te...
Nutritional properties of fufu analog produced from co-processing of cassava and cocoyam were studied. Cassava and cocoyam were fermented for 72 h, dried to obtain fufu flour. Proximate, functional, minerals, antinutritional factor, pasting properties, and sensory evaluation of various samples were determined. The results revealed that the moisture contents of the samples showed significant dif...
Production of αamylase under solid state fermentation by Streptomyces erumpens MTCC 7317 was investigated using cassava fibrous residue, one of the major solid waste released during extraction of starch from cassava (Manihot esculenta Crantz). Response surface methodology (RSM) was used to evaluate the effect of the main variables, i.e., incubation period (60 h), moisture holding capacity (60%)...
In Vietnam, cassava (Manihot esculenta Crantz) is the second most important food crop after rice in terms of total production; annual root production is about 2 million tonnes, the majority of which is used for animal feeding. Cassava is also an important source of income for poor farmers. Making silage is an appropriate method to preserve cassava roots to be used for pig feeding and is applica...
KT/HAK/KUP (KUP) family is responsible for potassium ion (K+) transport, which plays a vital role in the response of plants to abiotic stress by maintaining osmotic balance. However, our understanding of the functions of the KUP family in the drought-resistant crop cassava (Manihot esculenta Crantz) is limited. In the present study, 21 cassava KUP genes (MeKUPs) were identified and classified i...
A clear association between seasonal outbreaks of a paralytic disease called konzo and toxic effects from consumption of insufficiently processed bitter cassava roots has been demonstrated in Bandundu region, Zaire. A community-based survey of 6764 inhabitants identified 110 live and 24 dead konzo-affected persons with a history of isolated non-progressive spastic paraparesis of abrupt onset. T...
Lactic acid is one of the functional and valuable compounds utilized in food, pharmaceutical, and chemical industries while Poly lactic acid (PLA) is a biodegradable polymer that has a variety of applications. In recent years, microbial conversion of renewable raw materials has become an important objective in industrial biotechnology. Among many raw materials available, tapioca starch is consi...
