Optimization and Characterization of Spirulina and Chlorella Hydrolysates for Industrial Application.

Chlorella and Spirulina are the most used microalgae mainly as powder, tablets, or capsules. However, the recent change in lifestyle of modern society encouraged the emergence of liquid food supplements. The current work evaluated the efficiency of several hydrolysis methods (ultrasound-assisted hydrolysis UAH, acid hydrolysis AH, autoclave-assisted hydrolysis AAH, and enzymatic hydrolysis EH) in order to develop liquid dietary supplements from Chlorella and Spirulina biomasses.

Origin, Early History, Cultivation, and Characteristics of the Traditional Varieties of Moroccan L.

has been cultivated and used for centuries in the north Moroccan Rif (local name is ). However, its history is poorly known and the date of its first introduction and dispersal in Morocco is still difficult to be precise. The purpose of the present work is to review the literature on the origin, history, and cultivation of in Morocco, as well as data on the morphological, genetic, and phytochemical characteristics of local cultivated varieties.

Synthesis and characterization of arginine-doped heliotrope leaves with high clean-up capacity for crystal violet dye from aqueous media.

A novel arginine-modified Heliotrope leaf (Arg@HL) was used as adsorbent for the crystal violet (CV) dye adsorption in a batch process. The physicochemical and morphological composition of Arg@HL were characterized by field-emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). The experiments were carried out to investigate the factors that influence the dye uptake by the adsorbent, such as the contact time under agitation, adsorbent amount, initial dye concentration, temperature and pH of dye solution.

An ethnobotanical survey of medicinal plants used for diabetes treatment in Rabat, Morocco.

Diabetes mellitus is a major public health problem in Morocco. The value of ethnobotanical information is now increasingly acknowledged. To inventory and to provide ethnobotanical information on some of the medicinal plants used in traditional medicine to treat diabetes in Rabat (Morocco), a survey was undertaken from March 1 to April 30 2018.

Successful nodulation of Casuarina by Frankia in axenic conditions.

Aims: In order to depict the fine interactions that lead to nodulation, absolute microbiological control of the symbiotic partners is required, i.e. the ability to obtain in vitro axenic nodulation, a condition that has never been fulfilled with the Casuarina-Frankia symbiosis.
