The fuel properties of microalgal biodiesel are predicted using published microalgal fatty acid (FA) compositions and predictive fuel models. Biodiesels produced from the microalgae investigated are predicted to have extremely poor oxidative stabilities and the majority also have poor cold-flow properties. The cetane number in most cases is out of… (More)
Energy fuels for transportation and electricity generation are mainly derived from finite and declining reserves of fossil hydrocarbons. Fossil hydrocarbons are also used to produce a wide range of organic carbon-based chemical products. The current global dependency on fossil hydrocarbons will not be environmentally or economically sustainable in the long… (More)
BACKGROUND AND AIMS The aim of this study was to investigate the effects of the interactions between the microbial symbionts, Rhizobium and arbuscular mycorrhizal fungi (AMF) on N and P accumulation by broad bean (Vicia faba) and how increased N and P content influence biomass production, leaf area and net photosynthetic rate. METHODS A multi-factorial… (More)
Culture of cassava somatic embryos on media with an altered macro- and micro-nutrient salt concentration affected embryo development and germination capability. In the tests, quarter-, half-, full- or double-strength Murashige and Skoog (MS) media were compared. The maximum number of somatic embryos differentiated from a proliferative nodular embryogenic… (More)
Here, we report on the draft genome sequence of Serratia sp. strain TEL, associated with Oscheius sp. TEL-2014 (Nematoda: Rhabditidae, KM492926) isolated from a grassland in Suikerbosrand Nature Reserve near Johannesburg in South Africa. Serratia sp. strain TEL has a genome size of 5,000,541 bp with 4,647 genes and a G+C content of 59.1%.
Here we report on the draft genome sequence of Serratia marcescens strain MCB associated with Oscheius sp. MCB (Nematoda: Rhabditidae) isolated from South African soil. S. marcescens strain MCB has 5,304,212-bp genome size with 4,877 genes and a G+C content of 59.1%.
In the sentence " The CN of a specific biodiesel/FAME mixture is then given by the following equation, where CN i and m i are the cetane number and mass percentage of each FAME in the biodiesel " mass percentage should read mass fraction. The corrected sentence is shown below. The CN of a specific biodiesel/FAME mixture is then given by the following… (More)
AIMS To test the effects of C : N : P ratio modification of a well-known nutrient medium formulation, the Endo formulation on biofilm formation by Enterobacter cloacae Ecl and Citrobacter freundii Cf1 in both single-species and binary species biofilms. METHODS AND RESULTS The C : N : P atom : atom ratio of a well-known nutrient medium formulation, the… (More)
Increasingly lignocellulosic biomass hydrolysates are used as the feedstock for industrial fermentations. These biomass hydrolysates consist of complex mixtures of different fermentable sugars, but also contain inhibitors and salts that affect the performance of the product-generating microbes. The performance of six industrially relevant microorganisms,… (More)
We report here the draft genome sequence of Xenorhabdus khoisanae strain MCB, a Gram-negative bacterium and symbiont of a Steinernema entomopathogenic nematode. The genome assembly consists of 266 contigs covering 4.68 Mb. Genome annotation revealed 3,869 protein-coding sequences, with a G+C content of 43.5%.
