isolation and characterization of xylitol-producing yeasts from the gut of colleopteran insects.	a total of 35 yeasts were isolated from the gut of beetles collected from hyderabad city, india. twenty of these yeasts utilized xylose as a sole carbon source but only 12 of these converted xylose to xylitol. the ability to convert xylose to xylitol varied among the isolates and ranged from 0.12 to 0.58 g/g xylose. based on the phenotypic characteristics and phylogenetic analysis of the d1/d2 domain sequence of 26s rrna gene, these isolates were identified as members of pichia, candida, issatch ...	2007	17710483
photosynthetic pathway and biomass energy production.	the current interest in locating new or alternative sources of energy has focused attention on solar energy capture by crops that can be subsequently utilized as a substitute for fossil fuels. the very high productivity of sugarepane and the fact that it accumulates sugars that are directly fermentable to alcohol may have caused seemingly less productive crops to be overlooked. we show here that recoverable alcohol from achievable commercial yields of pineapple can actually equal that of sugarca ...	1979	17729660

domestication to crop improvement: genetic resources for sorghum and saccharum (andropogoneae).	both sorghum (sorghum bicolor) and sugarcane (saccharum officinarum) are members of the andropogoneae tribe in the poaceae and are each other's closest relatives amongst cultivated plants. both are relatively recent domesticates and comparatively little of the genetic potential of these taxa and their wild relatives has been captured by breeding programmes to date. this review assesses the genetic gains made by plant breeders since domestication and the progress in the characterization of geneti ...	2007	17766842
simultaneous saccharification and fermentation of steam-pretreated bagasse using saccharomyces cerevisiae tmb3400 and pichia stipitis cbs6054.	sugarcane bagasse--a residue from sugar and ethanol production from sugar cane--is a potential raw material for lignocellulosic ethanol production. this material is high in xylan content. a prerequisite for bioethanol production from bagasse is therefore that xylose is efficiently fermented to ethanol. in the current study, ethanolic fermentation of steam-pretreated sugarcane bagasse was assessed in a simultaneous saccharification and fermentation (ssf) set-up using either saccharomyces cerevisi ...	2008	17787015
inhibition of agrobacterium-induced cell death by antiapoptotic gene expression leads to very high transformation efficiency of banana.	the death of plant cells in culture following exposure to agrobacterium tumefaciens remains a major obstacle in developing agrobacterium-mediated transformation into a highly efficient genotype-independent technology. here, we present evidence that a. tumefaciens exposure induces cell death in banana cell suspensions. more than 90% of embryogenic banana cells died after exposure to a. tumefaciens and cell death was accompanied by a subset of features associated with apoptosis in mammalian cells, ...	2007	17849707
