Abstract:

Polyacrylamide and polysaccharides are commonly used polymers, but they have certain disadvantages. Hydrolyzed polyacrylamide (HPAM) is particularly susceptible to harsh reservoir conditions, including high shear forces, salinity, and temperature. Xanthan gum biopolymer has drawbacks, such as high cost and susceptibility to reservoir biodegradation. In contrast, pectin is a viable alternative owing to its excellent biodegradability, natural decomposition, transparency, good elongation properties, and strong gel-forming ability. In this study, we characterize and analyze the rheology of biopoly

Biopolymers are a suitable alternative for the ongoing problem of plastic accumulation, even though commercialization is difficult, which is reflected in the price of the product. However, costs can be reduced if active sludge bacteria and cheap, accessible substrates such as waste brewer’s yeast are used. Waste brewer’s yeast is a rich source of carbon and nitrogen and is widespread as a substrate in various industries. Thus, the cultivation of active sludge bacteria was performed on waste brewers’ yeast to obtain biopolymers that can be used in 3D printing. FT-IR, TG, and DSC analyses of pro

Symptoms can be local or general, leading to a systemic inflammatory autoimmune syndrome induced by adjuvants. Method: A patient operated by open method for the surgical extraction of allogenic substances in the gluteal region is described. Results: A 46-year-old female patient with a history of injection of more than 1000 ml of liquid silicone in both buttock

Abstract:

Marine algae represent an underutilized biomass resource. Biopolymers can be extracted from different types of algae. Alginates and carrageenans are among the most common biopolymers extracted from brown and red algae. They find applications in the food and biomaterials industries, among others. However, other available marine algae are not commercially exploited. For instance, green algae from the Ulvaceae family remain largely unexploited and have no industrial applications. In particular, Ulva species can serve as a promising source for the extraction of a biopolymer known as ulvan. This wo

Processes of extracting hemicellulose from annual plants usually neglect the cellulose fraction. This study explored the possibility of obtaining both a hemicellulose and a cellulose fraction of sufficient quality for further use, with barley husks used as the raw material. An alkaline extraction was used to isolate the biopolymers by a process in which sodium dithionite replaced the traditional sodium borohydride as the reducing agent. The cellulose fraction was successfully transformed into nanocellulose by sulfuric acid hydrolysis, and the obtained hemicellulose (i.e., arabinoxylan) display
