1. Growth of Burkholderia sacchari LFM 101 cultivated in glucose, sucrose and glycerol at different temperatures
ABSTRACT Polyhydroxyalkanoates (PHAs) have attracted major industrial interest as alternatives to conventional plastics. They are produced by several bacteria as cytoplasmic inclusions when nutrients are in limited supply. Among the many factors influencing bacterial growth, the effect of temperature on both specific growth rates and growth yields in terms o

2. Isolamento de bactérias produtoras de polihidroxialcanoatos e caracterização molecular de sua PHA sintase. / Isolation of polyhydroxyalkanoates producing bacteria and molecular characterization of their PHA synthase.
A total of 1520 isolates from domestic sewage sludge or soil of preserved area were evaluated in regards of PHA production using the lipophilic Nile Red A or Sudan Black B dyes, allowing the detection of 261 isolates. PHA production experiments revealed P3HB producing isolates at higher amounts than the strain Burkholderia sacchari LFM101 and PHAMCL producti

3. Avaliação do potencial de Burkholderia sacchari produzir o copolimero biodegradável poli(3-hidroxibutirato-co-3-hidroxihexanoato) [P(3HB-co-3HHX)]. / Evaluating the potential of Burkholderia sacchari to produce the biodegradable copolymer poly (3-hydroxybutirate-co-3-hydroxyhexanoate).
The ability of B. sacchari to accumulate poly-3-hydroxybutyrate-co-3-hydroxyhexanoate (P3HB-co-3HHx) from glucose and hexanoic acid was confirmed. 3HHx content was up to 2 mol% of PHA (<10% of the maximum theoretical 3HHx from the acid), indicating a substrate flexibility of B. sacchari PHA synthase, but high efficiency of hexanoate catabolic pathways.

4. Is propionate alfa-oxidation involved in the reduction of biodegradable plastic production in Burkholderia sacchari? / Alfa-oxidação de propionato está envolvida na redução da produção de plástico biodegradável em Burkholderia sacchari?
Burkholderia sacchari is a new bacterial species from brazilian soil, able to grow in sucrose, accumulating intracellular granules of polyester belonging to the polyhydroxyalkanoate family (PHA). When cultivated on sucrose, the homopolymer poly-3-hydroxybutyrate is accumulated by this bacterium, which is used as biodegradable and biocompatible plastic. When

5. The Composition a evaluate the polymer biodegradable produce for Burkholderia sacchari with the different substrates / Avaliação da composição de polímeros biodegradáveis produzidos por Burkholderia sacchari a partir de diferentes substratos
The bacterial production of polyesters belonging to the polyhydroxyalkanoate family (PHA) has generated biodegradable, biocompatible and environmentally friendly new materials. Properties and applications of PHA depend on monomer composition, which is dependent both on the substrate available and the metabolic apparatus of the PHA-producing microorganism. Bu

6. Identification of the 2-Methylcitrate Pathway Involved in the Catabolism of Propionate in the Polyhydroxyalkanoate-Producing Strain Burkholderia sacchari IPT101T and Analysis of a Mutant Accumulating a Copolyester with Higher 3-Hydroxyvalerate Content
Burkholderia sacchari IPT101T induced the formation of 2-methylcitrate synthase and 2-methylisocitrate lyase when it was cultivated in the presence of propionic acid. The prp locus of B. sacchari IPT101T is required for utilization of propionic acid as a sole carbon source and is relevant for incorporation of 3-hydroxyvalerate (3HV) into copolyesters, and it
