Abstract:

The problem of food agro-industry residues represents a growing concern in our society, therefore its use as a raw material to obtain biopolymers of technological interest is an attractive alternative. The objective of this work was to assess the viability of utilizing cardol, derived from cashew nut shell liquid, in the production of a biopolymer composite by combining it with cassava starch. The biopolymer composite was prepared by thermochemical method using different cardol concentrations and varying the synthesis pH. The results allowed us to demonstrate the formation of cardol/starch bio

Abstract:

Six microalgae strains were screened according to their biomass productivity and polymer synthesis, showing biomass productivity between 0.14 and 0.68 g/(L·d) for a 21-day growth period. Extracellular biopolymers from the spent culture media of Nostoc sp. (No), Synechocystis sp. (Sy), and Porphyridium purpureum (Pp) was obtained, and the yields of the clean biopolymer were 323, 204, and 83 mg/L, respectively. The crude biopolymer was cleaned up using a solid-phase extraction technique. The emulsification index E24 values for the clean biopolymer were 77.5%, 68.8%, and 73.3% at 0.323, 0.083, an

Due to the complex structures of living systems, the use of microtechnology to recreate in vivo architecture has exciting potential applications. Living tissues maintain a well-organized three-dimensional (3-D) architecture, with “micro” and “nano” scale features. Microtechnologies offer the new possibility of designing and building sensors and devices in dimensional scales close to that of living tissues.1–2 However, most available microscale systems are two-dimensional, and few 3-D systems are being explored. Therefore, we have developed a versatile technique to create a 3-D microscale hiera

Abstract:

The accumulation of biopolymers in porous media, produced by stimulating either indigenous bacteria or artificially introduced microbes, readily blocks pore throats and can effectively reduce bulk permeability. Such a microbial clogging treatment can be used for selective plugging of permeable zones in reservoirs and is considered a potentially promising approach to enhance sweep efficiency for microbial enhanced oil recovery (MEOR). Monitoring in situ microbial growth, biopolymer formation, and permeability reduction in the reservoir is critical for successful application of this MEOR approac

Abstract:

Measures to endorse the adoption of eco-friendly biodegradable plastics as a response to the scale of plastic pollution has created a demand for innovative products from materials from Nature. Ionic liquids (ILs) have the ability to disrupt the hydrogen bonding network of biopolymers, increase the mobility of biopolymer chains, reduce friction, and produce materials with various morphologies and mechanical properties. Due to these qualities, ILs are considered ideal for plasticizing biopolymers, enabling them to meet a wide range of specifications for biopolymeric materials. This mini-review d

Abstract:

Matrigel, a mouse sarcoma-derived extract, is considered the gold standard for organoid cultures. However, it has several drawbacks, including inconsistent and ill-defined composition, varying quality between batches, and potential cancer-related health risks. These factors highlight the need to develop chemically defined alternatives to Matrigel. Natural biopolymers derived from living organisms have emerged as promising substitutes capable of creating chemically defined extracellular matrix (ECM)-mimicking materials to support organoids in a 3-dimensional (3D) environment.
