Abstract: The present invention relates to a process for reducing the solvent content from a biodegradable polymer in a composition or a preparation. The process comprises drying the biopolymer composition by submitting it to microwaves for a time to achieve removal of the solvent at desired levels.

Abstract: The present invention relates to a flexographic water based ink in which a biodegradable polymer, such a polyhy-droxyalkanoate (PHA), replaces conventional poorly or non-biodegradable organic polymeric resins for example. PHAs are used as a latex suspension in water, thus the present invention relates to a novel pigment/latex mixture. PHA in a latex form is a fluid vehicle in which all the other components necessary to provide a flexographic ink are added, i.e., pigments, wax and/or binder, as well as a solvent, if necessary. The PHAs are mainly responsible for the biodegradability of the flexographic water based ink. The present invention relates also a method to produce a flexographic water based composition with enhanced biodegradability properties.

Abstract: The present invention provides a method for making biodegradable and bioresorbable biomaterials that are also characterized by its malleability. Any desired shape can be obtained from this material, resulting from the specific composition of this invention. Therefore, the biomaterial of the present invention is very well suited to be used as in preparation of implants for dental applications, or as in the case of difficult accessible sites such as bone cavities. Composition of the biomaterial comprises an hydrophobic biopolymer, a compound having both hydrophilic and hydrophobic properties, bone regenerative entity that help in the bone regeneration. In addition, these biomaterials can be used as vehicle for the release of biologically active entities or drugs, such as growth factors or analgesics for example.

Abstract: The formation of a cream and gel is described using a biopolymer, such as a polyhydroxyalkanoate (PHA), a polylactide (PLA), a polylactideglycolide (PLGA) and a polyglycoside (PGA), or a derivative thereof, in a latex form with the addition of a binder, which is generally an amphiphilic chemical entity. An hydrophobic domain of the amphiphilic chemical entity interacts with at least one biopolymer forming a water soluble complex, while the hydrophilic domain of the amphiphilic chemical entity maintains the soluble complex in suspension in an aqueous solution, which after proper heating becomes a gel or a cream. As a result, a versatile gel or cream is created with different compositions and textures that are obtained based on the nature of the binder used and the ratio of biopolymers and binder(s).

Abstract: The present invention relates to a process of production of polyhydroxyalkanoate (PHA) by incubating PHA producing microorganisms in a medium containing starch, starch extracts, or derivatives as sources of carbon. The process comprises also the synthesis of derived compounds belonging to the chemical family of PHA.
