This study investigated the metabolizable energy (ME) intake, net energy of production (NEp), heat production (HP), efficiencies of ME use for energy, lipid and protein retention as well as the performance of broiler chickens fed diets based on cassava chips or pellets with or without supplementation with an enzyme product containing xylanase, amylase, protease and phytase. The two products, ca...

PALAVRAS-CHAVE Manihot esculenta Crantz Cianeto Carotenoides Proteína ABSTRACT: Cassava (Manihot esculenta Crantz) is a plant from the Brazilian Amazonia which presents wide genetic variability. Since it is one of the most consumed foods in the world, efforts to generate more nutritive cultivars are necessary. The objective of the present study was to characterize twenty genotypes of cassava fr...

Cyclodextrin glycosyltransferase (CGTase) catalyzes the conversion of starch into non-reducing cyclic sugars, cyclodextrins, which have several industrial applications. This study aimed to establish optimal culture conditions for β-CGTase production by Bacillus sp. SM-02, isolated from soil of cassava industries waste water lake. The optimization was performed by Central Composite Design (CCD) ...

Exploring new raw starch-hydrolyzing ?-amylases and understanding their biochemical characteristics are important for the utilization of starch-rich materials in bio-industry. In this work, a novel starch-degrading ?-amylase (HL11 Amy) from Roseateles terrae HL11 was firstly reported. Evolutionary analysis revealed that HL11Amy classified into glycoside hydrolase family 13 subfamily 32 (GH13_32...

a research was conducted to evaluate cassava production by women farmers in igbo-eze north local government area of enugu state, nigeria. one hundred and twenty smallholder female cassava farmers were selected using multi-stage sampling. data were collected from the respondents using questionnaire and interview schedule. then descriptive statistics (mean, frequency and percentage) were used in ...

BACKGROUND The nutritional quality of cassava complementary porridge was improved through extrusion cooking and compositing with either defatted or full fat soy flour (65:35 w/w), and product acceptability by mothers with children of the target population was evaluated. RESULTS The protein digestibility-corrected amino acid score (PDCAAS) of extrusion- and conventionally cooked composite porr...

A simple, nonaseptic, low-cast process for the conversion of cassava, a starchy tropical root crop, into microbial protein for use as animal feed was sought. Screening tests culminated in the isolation of a thermotolerant, amylase-producing mold, designated I-21, which was identified as Aspergillus fumigatus. The optimum pH for protein synthesis was 3-5, but the optimum temperature was less tha...

To date, transgenic approaches to biofortify subsistence crops have been rather limited. This is particularly true for the starchy root crop cassava (Manihot esculenta Crantz). Cassava has one of the highest rates of CO(2) fixation and sucrose synthesis for any C3 plant, but rarely reaches its yield potentials in the field. It was our hypothesis that starch production in cassava tuberous roots ...
