The aim of this research was to study the biodegradation of a polymer derived from castor oil, which is a renewable, natural material that is a practical alternative for the replacement of traditional polyurethane foams. Due to its molecular structure, which contains polyester segments derived from vegetable oil, the polymeric surface is susceptible to microorganism attack. This study tested th...

Lignocellulosic materials are considered the most abundant renewable resource available for the Bioethanol Production. Water Hyacinth is one of potential raw material of the world’s worst aquatic plant as a feedstock to produce Bioethanol. The purposed this research is obtain reduced of matter for biodegradation lignin in Biological pretreatment with White Rot Fungi eg. Phanerochaete Chrysospor...

Biodegradation offers an eco-friendly option for disposal of waste coming from different breweries and wineries. A model-based analysis through rigorous experimentation has been accomplished to study different aspects of the biodegradation of distillery wastes. Using distillery waste as resource material, energy is derived in the form of biogas containing high percentage of methane which is pro...

A microcosm study was conducted to investigate the degradation of mono- and polyaromatic hydrocarbons under in situ-like conditions using alluvial sediments from the site of a former cokery. Benzene, naphthalene, or acenaphthene were added to the sediments as (13)C-labeled substrates. Based on the evolution of (13)C-CO(2) determined by gas chromatography isotope-ratio mass spectrometry (GC-IRMS...

We studied and quantified the elimination of sunflower oil from a wastewater influent using a biological treatment by activated sludge. Estimation of the biodegraded material was obtained doing a mass balance, and we conducted a follow-up of the different operational parameters and design. We delivered information about the operation of a system for treatment by activated sludge fed with an inf...

A nano-hydroxyapatite/collagen composite was prepared by precipitation of hydroxyapatite from an aqueous solution onto collagen. Mouse peritoneal macrophages were used to investigate the in vitro biodegradation of the composite. The results showed the mechanism of phagocytosis and extracellular degradation process. The cells that belong to the mononuclear phagocyte system showed some morphologi...

The functional properties of six distinct electrospun silk material groups were evaluated to assess conformational and biocompatible characteristics related to wound dressings. In a hydrated state, all six silk matrices exhibited absorption, water vapor transmission, oxygen permeation and enzymatic biodegradation suitable for full-thickness wound sites. Employing constrained drying techniques, ...

Silk from the Bombyx mori silkworm is a protein-based fiber. Bombyx mori silk fibroin (SF) is one of the most important candidates for biomedical porous material based on its superior machinability, biocompatibility, biodegradation, bioresorbability, and so on. In this paper, we have reviewed the key features of SF. Moreover we have focused on the morphous, technical processing, and biocompatib...
