Olive milling wastewater is a major problem facing the Mediterranean countries producing olive oil like Egypt. In the present study, olive milling wastewater rich with organic phenolic compounds, macro and micro nutrients was used as growing media for cyanobacteria. The cyanobacteria were grown on wastewater to obtain two biofertilizers, one biofor...

Plants of the Hypericum L. genus are widely distributed with several identified speciesall over the world. In addition to their nutritional properties, plants of the Hypericum L.genus are also noteworthy for their pharmacological properties. These plants have long beena part of traditional medicine in many nations. The present work presents a brief...

Simple Summary With advances in scientific research and a better understanding of rabbit physiology, emphasis has shifted to optimizing feed nutritional composition and investigating novel nutritional supplements. These supplements are intended to improve performance, immunological function, and to mitigate the negative impacts of heat stress on ra...

Background: With the recent use and development of nanomaterials, silver nanoparticles (AgNPs) are gaining much attention as a promising antibacterial agent for use in caries prevention. Objectives: This study aimed to biosynthesize AgNPs using chamomile extract as a reducing agent and to investigate its inhibitory effect against Streptococcus m...

This study aimed to evaluate the efficacy of dietary Acacia nilotica bark bioactive lipid compounds (ANBBLCs) as novel feed additives on the growth performance, carcass criteria, antioxidants, and antimicrobial activities of growing male rabbits. A total of 100 California male weanling rabbits aged 35 days were divided into four nutritional treatme...

Abstract Many thermally processed foods contain the potential carcinogens furan and acrylamide. They are acknowledged as hazardous and "potentially carcinogenic to humans," according to the International Agency for Research on Cancer. The present study's objectives are to investigate the potential impact of low heat and low irradiation doses on red...

Algae" represent a diverse group of photosynthetic organisms ranging from single cell to massive kelp that are found in all ecosystems on our planet. Algae play an essential role for life; they account for almost 50% of the photosynthesis activity on earth. The biochemical composition of algae includes a variety of high-value products such as pigme...

The current COVID-19 pandemic is the main issue globally, and finding solutions either for disease prevention or treatment is nowadays a key scientific concern. Good immunity can be shown as the only proven method of overcoming or minimizing the adverse effects of virus infections. Since Coronavirus spread, different conventional herbs were used as...

In the present work, a green method is proposed for biosynthesis of silver nanoparticles (AgNPs) using artichoke processing waste extract as reducing agent. The formation of AgNPs was spectrophotometrically detected by the appearance of maximum peak at 430 nm. Transmission electron microscopic results confirmed the formation of AgNPs with different...

Nowadays, the use of natural bio-products in pharmaceuticals is gaining popularity as safe alternatives to chemicals and synthetic drugs. Algal products are offering a pure, healthy and sustainable choice for pharmaceutical applications. Algae are photosynthetic microorganisms that can survive in different environmental conditions. Algae have many...

Algae are among the wealthiestaquatic commodities that are considered healthy and have negligible effect onhuman cytotoxicity. They are considered as a resourceful material for bioactivecompounds, including vitamins, po...

Ultrasonic-assisted extraction (UAE) is increasingly emerging as a highly effective extraction technique. This extraction technique is affected by several experimental factors. The present work aimed to optimize the ultrasonic-assisted extraction of antioxidants from Ulva lactuca (sea lettuce), widespread macroalgae growing along the Mediterranean...

Fresh water resources in terms of water quality is a crucial issue worldwide. In Egypt, the Nile River is the main source of fresh water in the country and monitoring its water quality is a major task on governments and research levels. In the present case study, the physical, chemical and algal distribution in Nile River was monitored over two sea...

Marine algae (Seaweeds) are photosynthetic organisms living in seas and oceans. They are known to have several benefits and are recognized as a source of several important bioactive compounds. In the present review, we present brief information concerning marine algae, their classification, distribution, and importance. Also, we are focusing on stu...

In the present study, water quality parameters and planktons distribution were monitored monthly during the year 2018 within a segment of the Nile around El-Maadi area in Cairo, Egypt. The results indicated a temperature variation ranging from 16.8°C in January to 29.4°C in July. The pH of water recorded a value around 8.2 all over the study period...

In recent decades, natural antioxidant alternatives have become a trending topic for replacing artificial antioxidants. Microalgae have been reported to display interesting bioactive properties and their antioxidant activity is one of them. This study aims to evaluate the antioxidant capacity, phytochemical constituents and proximate composition of...
