Candida tropicalis grows on soluble starch, corn, and cassava powders without requiring that these substrates be previously hydrolyzed. C. tropicalis possesses the enzyme needed to hydrolyze starch, namely, an alpha-amylase. That property has been used to develop a fermentation process whereby C. tropicalis can be grown directly on corn or cassava powders so that the resultant mixture of biomas...

The chemical compounds of kaffir lime leaves oleoresin and the preservative effects of kaffir lime leaves oleoresin incorporation on cassava starch-based edible coatings for fresh beef during 14 days refrigerated storage were investigated to determine their ability to extend beef shelf life. Beef characteristic was determined based on microbiological (Total Plate Count/ TPC), chemical (Total Vo...

Edible films from chitosan, cassava starch, and gelatin plasticized with glycerol have been developed by casting method, and the effects of cassava starch (50, 100 and 150 g per 100 g of chitosan), gelatin (0, 25 and 50 g per 100 g of chitosan) and glycerol (21, 42 and 63 g per 100 g of chitosan) from the film solution on various properties of chitosan-based films have been studied using respon...

Cassava (Manihot esculenta Crantz) wild relatives remain a largely untapped potential for genetic improvement. However, the domestication syndrome phenomena from wild species to cultivated cassava remain poorly understood. The analysis of leaf anatomy and photosynthetic activity showed significantly different between cassava cultivars SC205, SC8 and wild relative M. esculenta ssp. Flabellifolia...

BACKGROUND Cassava starch is considered as a potential source for the commercial production of bioethanol because of its availability and low market price. It can be used as a basic source to support large-scale biological production of bioethanol using microbial amylases. With the progression and advancement in enzymology, starch liquefying and saccharifying enzymes are preferred for the conve...

Retrotransposons are ubiquitous in eukaryotic genomes and now proving to be useful genetic tools for genetic diversity and phylogenetic analyses, especially in plants. In order to assess the diversity of Ty1/Copia-like retrotransposons of cassava, we used PCR primers anchored on the conserved domains of reverse transcriptases (RTs) to amplify cassava Ty1/Copia-like RT. The PCR product was clon...

To examine the interactions of starch and sugar metabolism on photosynthesis in cassava, a heat-girdling treatment was applied to petioles of cassava leaves at the end of the light cycle to inhibit starch remobilization during the night. The inhibition of starch remobilization caused significant starch accumulation at the beginning of the light cycle, inhibited photosynthesis, and affected intr...

Starchgelatin binary binder mixtures were applied in the formulation of sodium salicylate tablets. Locally developed cassava starch (tapioca starch) was used as a co-binder with gelatin. Wet granulation method was used to formulate different batches of sodium salicylate tablets with varying binder concentrations (1-5%w/w) and starch – gelatin binder ratios (25:75, 50:50, 75:25 and 0:100). The s...

Cassava (Manihot esculenta Crantz) is a highly productive tuber crop growing on marginal land, providing rural communities in India with nutritious food, as well as income generated by huge industrial demand for sago and starch. In Tamil Nadu (TN) alone it supports over 10,000 smallholder farmers. To sustain the livelihoods of this community of smallholder farmers, the Indo-Swiss Collaboration ...

Cassava (Manihot esculenta) is valued mainly for high content starch in its roots. Our understanding of mechanisms promoting high starch accumulation in the roots is, however, still very limited. Two field-grown cassava cultivars, Huanan 124(H124) with low root starch and Fuxuan 01(F01) with high root starch, were characterised comparatively at four main growth stages. Changes in key sugars in ...
