“…Continuous microscopically investigation for algal community was carried out three times a week. Algal biomass is harvested biweekly from high rate algal pond (6m 3 ) and precipitated by cationic starch [16]. The collected biomass is dried using sun drier and grinded to fine particles (0.1mm)…”

C-Phycocyanin is among the most promising microalgal derived molecules with an array of pharmacological activities. Toll-like receptors (TLRs) have a vital role in regulating inflammatory response in renal injury. The aim of this study was to evaluate the possible renal therapeutic effect of phycocyanin isolated from Microcystis aeruginosa Kützing harvested from high-rate algal pond on potassium dichromate (PD)-induced renal injury in rats. Rats were assigned randomly into: Group I: Normal control group. Group II: Rats injected with a single injection of PD (15 mg/kg; s.c) and served as renal injury group. Group III and IV: Rats received C-phycocyanin (25 & 50 mg/kg body weight; orally), after PD injection, daily for 7 days. Injection of PD induced a marked renal injury, evidenced by a significant increase in kidney functions and renal contents of malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α), toll-like receptor 4 (TLR4), heat shock protein 70 (HSP70) and insulin growth factor-1 (IGF-1) In addition PD reduced renal content of reduced glutathione (GSH) and exhibited tubular degeneration and necrosis. C-phycocyanin has renal therapeutic effect against renal injury induced by PD through improving kidney function, down regulation of oxidative stress and TLR4/TNF-α/HSP70 inflammatory pathway as well as modulation of IGF-1.

“…Selected thirty mice of uniform weight are taken and divided into five groups each of six. The coagulants (cationic starches 1, 2, 3 and 4) and aluminum sulfate were dissolved in distilled water then given orally to four groups of mice in graded doses (1gm, 2gm, 3gm 4gm) up to 5 g/kg (El Naggar et al, 2018). In addition, the Non-Polar Fraction of dried Algal biomass (NPFA) was suspended in distilled water then given orally to rats in graded doses up to 5 g/kg.…”

Using microalgal biomass in animal diets has been studied recently. Many species of cultivated algae were found effective in maintaining animal growth performance, and in improving body weight. Using of microalgae collected from high rate algal ponds (HRAP) as a feed additive to broilers ration was studied. One hundred and twenty broiler chicks were divided into 6 groups of 20 birds, three of them have fed on balanced broiler ration supplied with 1% weight per weight (W/W) of microalgae biomass and have variable vaccination schemes of live attenuated and inactivated Newcastle disease virus (NDV) vaccines genotype II or either non-vaccinated control. In addition, the other 3 groups have fed on free microalgae biomass balanced ration with the same vaccination treatment. Furthermore, weight gain, antibody response, mortalities, viral shedding and normal viability of chickens were estimated in order to assess the efficiency of microalgae as a feed additive. The results showed that the microalgae have no hazard effect on feed and water intake as well as enhanced viability of chickens. And in regards to immune function and body weight, they have similar effect with the free microalgae groups in normal serological response and viral shedding post vaccination with NDV vaccines as well as similar protection rate and body weight gain. In conclusion, microalgae can be used in broiler ration with no deleterious effect on growth rate, weight gain, poultry viability and immune response. In conclusion dried microalgal biomass harvested from HRAP can be used in broiler ration with no deleterious effect on growth rate, weight gain, poultry viability and immune response. Furthermore, future studies should be applied with increasing microalgae percent in poultry feed up to 5, 10 or 20% (W/W) in order to assess better performance on poultry production.

“…Studies have shown that the use of cationic starch reduces biochemical oxygen levels, or the waste load, by half. [14][15][16] Paper producers and even corrugated cardboard producers use starch in their processes to increase physical resistance, and due to the acceleration of pigment deterioration in the recycling process. [17][18] It may be possible to increase resistance to light by adding chemicals into the coating formula during its preparation.…”

Introduction: Paper is the most important material of the printing industry and is being improved due to the increasing needs of industry. The most important process to improve the optical and physical properties of paper is the surface coating. Paper has a smoother and opaquer surface with surface coating. In addition, brightness, whiteness, and yellowness values are improved with surface coating. Ultraviolet (UV) light in sunlight causes changes in the structure of the paper and coating chemicals and accordingly causes yellowing. Para-amino benzoic acid (PABA), due to its chemical structure, is a UV-blocking agent used in sunscreen creams. Methods: The effect of PABA on paper gloss, yellowness, and lightfastness values was investigated by adding it into the surface coating formulation. For this purpose, coating formulations were prepared with cationic starch and 3%, 5%, and 7% PABA; coatings were applied to the paper according to laboratory condition standards. Coated papers were printed with an IGT-C1 lab-type offset printability device with magenta ink. The printed papers were then exposed to a light fastness test with Solarbox. The color, brightness, and yellowness values of all samples before and after lightfastness were measured with an X-Rite spectrophotometer. The gloss of coated and printed paper sample values was measured with a BYK-Gardner glossmeter. Results: The gloss values of paper to which PABA was added, increased; however, it was determined that these gloss values decreased after the lightfastness test. Conclusions: PABA-added cationic starch coatings are more affected by UV light than cationic starch coatings.
