Over the last decade, nanotechnology has widely addressed many nanomaterials in the biomedical area with an opportunity to achieve better-targeted delivery, effective treatment, and an improved safety profile. Nanocarriers have the potential property to protect the active molecule during drug delivery. Depending on the employing nanosystem, the del...
Chapter
The nanoscale field had gained the attention of the scientific community by the synthesis of nanomaterial with high optical, mechanical, chemical, and biological properties. This nanosized dimension creates an improvement of different properties of nanocomposites compared with the conventional one where nanocomposites are a combination of organic a...
Chapter
Olive oil production yields a large number of byproducts and wastes, including olive mill wastewater (OMW) and olive pomace. The recovery, biological activities, and general uses of these byproducts have been widely investigated, essentially based on their phenolic contents. Therefore, the present chapter provides a general description of olive byp...

The book will be a work of tertiary literature, meaning to bring together digested knowledge and to give an update on the status of the use of nanotechnology in water monitoring and wastewater treatment. Generally, water supply worldwide is struggling to keep up with rising demand, which is compounded by population increase, global climate change,...
Chapter
The establishment of sustainable treatment processes to ensure the supply of clean water has piqued the interest of wastewater management experts worldwide. Nanocellulose is unique in this application because of its abundance in nature, nano-dimension, high surface area, stability, and bio-compatibility for binding with various contaminants. This c...
Chapter
Nowadays, water pollution has become a major problem in the world. Heavy metals represent the major toxic hazardous pollutants affecting ecosystems as well as living systems and human health. They are well-known for their high persistence, bioaccumulation, and nonbiodegradable nature. Over the past years, many strategies have been evolved to solve...

Olive mill wastewater is a potent pollutant generated during the extraction of olive oil. This effluent poses a high toxicrisk to the environment due to its content of organic compounds, especially polyphenols. This study aims to investigate theimpact of phenolic compounds extracted from different varieties of olive mill wastewater on the rumen fun...

A field experiment was conducted at the farm of Tamil Nadu Agricultural University, India, during the Kharif season to study soil chemical properties, microbial biomass and soil enzyme dynamics on transplanted rice with organic amendments. Rice CO(R) 48 was used as a test variety. The experiment was laid out in randomized block design (RBD) with th...

Cellulose is among the world’s wealthiest biopolymers and primarily has a wood, plant, and microbial source. To date, cellulose nanofibers (CNFs) are synthesized under controlled conditions (temperature, pH, and agitation). The bacterial synthesis of CNFs, so-called bacterial cellulose (BC), has become actively interested in recent times. These eme...

Recently, nanomaterials were synthesized using a novel, environmentally friendly method. The utilization of Yarrowia lipolytica supernatant in the manufacture of zinc oxide nanoparticles is described in this paper (ZnO NPs). The reactional medium was exposed to various musical sounds (MSs) during the synthesis, including Quran sound, Tunisian music...

The bacteriocidal properties of silver nanoparticles (AgNPs) depend on their average diameter (toxicity increases with decreasing diameter). In the present work, we describe novel green chemistry biosynthesis of AgNPs from AgNO3 added to cell-free culture medium of baker’s yeast, Saccharomyces cerevisiae, yielding nanoparticles in the range 11–25 n...

A new emerging and green approach was used to synthesis nanomaterials. In the present study, we report the use of Yarrowia lipolytica supernatant in the synthesis of zinc oxide nanoparticles (ZnO NPs). During the synthesis, the reactional medium was subjected to different musical sounds (MSs) such as Quran sound, Tunisian music, and Flamingo. The o...

The outbreak of new coronavirus acute respiratory disease (SARS-CoV-2) has been a major global challenge for the scientifi c community to save humanity. While, the unviability of the vaccine keeps most classes of society, especially African countries, suff er from the healthcare problem. Conventional medicine plants become the alternative method fo...

Abstract The olive mill wastewater harbors several natural products that are generally wasted in the environment without valoriza-tion. The polyphenols are the most predominant compounds found in olive mill wastewater exhibiting toxic effects of the ecosystems when they disposed at high concentrations. Therefore, green technology was recently used...

It is well known that the lack of an effective treatment of tuna wash processing wastewater may pose substantial environmental and public health hazards. The present work investigates the performance of biological treatment of tuna wash processing wastewater (TWPW) by using Yarrowia lipolytica. Under optimized experimental conditions (pH “6.40–6.50...

A series of novel α‐(diphenylphosphoryl)‐ and α‐(diphenylphosphorothioyl)cycloalkanone oximes have been synthesized in search for novel bioactive molecules. Their structures were characterized by various spectroscopic methods including IR, NMR ( 1 H, 31 P, 13 C), mass spectrometry and single crystal X‐ray diffraction. The newly synthesized phosphor...

This research investigates an efficient dual valorization of olive mill wastewater in the biosynthesis of magnesium oxide nanoparticles, and in the depollution of the effluent by Yarrowia lipolytica growth evaluation. After removal of polyphenols, the recovered biophenols were reacted with the magnesium precursor to provide magnesium oxide nanopart...
Presentation
Background Olive mill wastewater (OMW) is a pollutant by-product from the olive oil production. It represents a serious economic and environmental concern due to the high content of organic matter. In this term, the OMW can be provide a source of valuable with a cost-effective compounds in aim to use in nanotechnology. The present work reports the...

During the winter season, the olive oil industry yields large quantities of olive mill wastewaters (OMW). This later is one of the most difficult industrial effluents with a negative impact on the environment (soil, water, plants, etc.) mainly attributed to its phenolic compounds. The purpose of this study is to determine the antibacterial and anti...
