Spirulina as a Natural Feed Additive: Impact on Health and Performance of Broilers and Laying Hens | Chapter 5 | Agricultural Sciences: Techniques and Innovations Vol. 2

This chapter provides a comprehensive review of the effects of incorporating Spirulina into poultry diets, focusing on its impact on growth performance, immune function, egg production, microbial control, and overall poultry health. Spirulina, a blue-green algae known for its rich nutrient profile, including proteins, vitamins, minerals, and bioactive compounds, offers a range of benefits when included in poultry nutrition. Studies have shown that Spirulina supplementation improves weight gain, feed conversion ratio, and immune responses in both broiler chickens and laying hens. Additionally, it enhances the quality of eggs, particularly yolk pigmentation, without affecting feed intake. Furthermore, Spirulina demonstrates antimicrobial properties, contributing to improved gut health by promoting beneficial bacteria and reducing harmful microorganisms. The chapter also explores the optimal inclusion levels of Spirulina in poultry diets, offering insights into its potential as a natural, sustainable supplement to enhance poultry productivity and welfare. Through an analysis of recent research, this chapter highlights the scientific evidence supporting the inclusion of Spirulina as an effective and safe nutritional supplement for poultry farming.

Extraction and Purification of C-Phycocyanin from Spirulina Powder and Evaluating its Anti-oxidant, Anti-coagulant and DNA Damage Prevention Properties | Chapter 2 | Advanced Concepts in Pharmaceutical Research Vol. 6

C-Phycocyanin (C-PC) is a phycobiliprotein found in blue-green algae, such as Spirulina platensis which is often used as a dietary nutritional supplement and exhibits a variety of pharmacological properties. Cyanobacteria and algae possess a wide range of colored compounds, including chlorophyll, carotenoids and phycobiliproteins. In this regard, extraction, partial purification, antioxidant, anticoagulation and prevention of DNA damage activity of C-PC were investigated. In the present study, a simple and efficient method to extract C-PC from Spirulina platensis dry powder is reported. Spirulina platensis dry powder was obtained from NB Laboratories Pvt. Ltd., Nagpur, India. The extractions were carried out using two different methods: cold maceration and sonication method. The extraction using the cold maceration method proved to be the most efficient method. The efficiency of extraction methods was determined by calculating the concentration and purity ratio of isolated C-PC. Obtained crud C-PC was purified by ammonium sulphate precipitation, dialysis and gel filtration and presented a final extraction yield of 3.27±0.09 mg/ml with a purity ratio of 2.317±0.08. When it was evaluated as an antioxidant in vitro, it was able for scavenging nitric oxide. SDS-PAGE results show that the 40% ammonium sulphate precipitated sample and dialyzed sample show two bands of C-PC i.e. α and β with 17 and 19kDa respectively along with other proteins. C-PC showed significant anticoagulation and prevention of DNA damage activity. C-PC is a significant contributor to DNA damage prevention by scavenging of –OH.

Cost Effective Cultivation of Spirulina platensis by Using Fish Waste Hydrolysate | Chapter 11 | Recent Progress in Microbiology and Biotechnology Vol.1

 The greatest problem in the world today is Global Food Protein Shortage. So, there is an urgent need

to find other protein sources. The best potential is seen in Single Cell Protein i.e. Spirulina platensis.
The purpose of this study was to assess the growth, biomass, and other useful compounds (Protein,
Chl-a, Chl-b, Carotenoids Phycocyanin) of Spirulina on cost effective alternative medium i.e. Fish
Waste Hydrolysate (FH) medium and Zarrouk’s medium (ZM) was used as standard. This study
showed better growth rate, biomass (protein content), high level of chlorophyll a and chlorophyll b
content, carotenoid, phycocyanin pigment production of Spirulina cultivated in Fish Waste Hydrolysate
medium. It is suggested that FH medium could be used as the alternative and cheap medium than
standard medium ZM.
