Nisin: A Novel Bio-Preservative for Food Industry

By: Ulaganathan Arisekar , Robinson Jeya Shakila , Rajendran Shalini , T. Surya

Page No : 35-41

Approaches to biological preservation are attractive as a safety criterion in foodstuffs with lower levels of additives and chemicals that typically serve to suppress microbial proliferation. Nisin is a natural preservative used in a variety of foods. Bacteriocin is primarily utilized in foods like meat and dairy products. Nisin is used more frequently in food because it is the only bacteriocin approved as a food preservative. Nisin inhibits pathogenic foodborne bacteria such as Listeria monocytogenes and many other gram-positive food spoilage organisms. The preservative nisin may be used alone, in conjunction with other preservatives, or in conjunction with several physical treatments. The physicochemical and biological characteristics of nisin are discussed in this article, along with the key variables influencing its antibacterial potency and its use as an additive directly integrated into food matrices.

By: M. Joshna , Cheryl Antony , S. Selvaraj , Robinson Jeya Shakila , S. Mahalakshmi

Page No : 51-62

Physiology is the scientific study of how the component parts of fish function together in the living fish. It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. The glands that secrete their products into the bloodstream and body tissues along with the central nervous system to control and regulate many kinds of body functions are known as endocrine gland. In fishes, various endocrine gland has been found associated with different tasks and functions. Recent advances in physiology and endocrinology plays a crucial role in increased production levels in the industry.

Structure and Function of Kisspeptin and Gonadotropin Releasing Hormone Neuroendocrine Systems and Their Application in Aquaculture Systems

By: Cheryl Antony , P. Ruby , S. Selvaraj , Robinson Jeya Shakila , V. Ezhilarasi

Page No : 63-71

Gonadotropin releasing hormone (GnRH) is the major neuroendocrine hormone regulating reproduction in vertebrates, including finfish and shellfish. In recent years, using in vitro and in vivo studies, kisspeptins has been shown to act as upstream modulator of GnRH secretion in few finfish species. Surprisingly, shellfish GnRH do not cluster within finfish GnRH, suggesting diversity in gnRH genes and their evolution in animal kingdom. Kisspeptin and GnRH analogues have been synthesized chemically and successfully used in induced reproduction of finfish. Studies on Kisspeptin and GnRH potency in induced maturation and spawning of shellfish are scarce. Seasonally, fish broodstock raised in captivity exhibit different form of reproductive dysfunction at the level of the neuroendocrine brain-pituitary-gonad axis. Reproductive dysfunctions are also observed during sexual differentiation and pubertal onset periods. To overcome these problems in the captivity, different hormonal preparations including kisspeptin and gonadotropin-releasing hormone preparations are used. The present paper highlights the structure and function of multiple kisspeptin and GnRH systems in fish and their application for controlling reproduction in aquaculture systems.

Phytosterol from Marine Algae as Feed Additive in Aquaculture

By: Cheryl Antony , S. Selvaraj , S. Mahalakshmi

Page No : 73-81

Aquaculture is growing faster compared to other animal food production sector, and this growth has been accompanied by a rapid increase in aqua feed production in recent years (FAO, 2020). Particularly, there is an increasing trend in the use of plant based compounds instead of using synthetic hormones and antibiotics for promoting growth, colouration and gametogenesis in fish. Many components have been found in marine algae such as phytosterols that have several beneficial effects. Phytosterol present in marine algae such as sterols and stanols are similar to cholesterol in terms of structure and function. Studies on phytosterols and their use as feed additive in fishes are limited. The phytochemicals are classified based on the chemical structures as alkaloids, flavonoids, pigments, terpenoids, steroids and essential oils. The phytochemicals present in the plants and algae possess many useful functions such as enhancing the growth rate, feed consumption and also act as an immunostimulant, antistress factor and possess antimicrobial properties. Phytosterols are the plant derived sterols belonging to the terpenoid chemical group present in higher plants and also in marine algae. The most common phytosterol include beta-Sitosterol, campestrol, stigmasterol and stigmastanol. The sterol distribution in plants varies with some species having only one or two whereas as some other possess many steroids. Phytosterols can only obtained by the animals through their diet they cannot be synthesized by them. Phytosterols present in the marine algae and plants possess many benefits in fishes as well as crustaceans.

Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Remediation of polluted sites using microbial process i.e., bioremediation has proven effective, efficient and reliable technique due to its eco-friendly features. Bioremediation is an option that offers the possibility to destroy or render harmless various pollutants using natural biological activity. As such, it uses relatively low-cost technology techniques, which generally have a high public acceptance and can often be carried out on site. It will not be always suitable, however, as the range of contaminants on which it is effective is limited, the time scales involved are relatively long, and the residual contaminant levels achievable may not always be appropriate. Hence, bioremediation is an innovative technology that has the potential to alleviate the toxic contaminants. In this review, we provide a comprehensive knowledge and pragmatic view on major bioremediation techniques, types of bioremediation and strategies, various types of bioremediation agents involved, types of contaminants, and the prospects of bioremediation to clean up the environment contaminants.

By: Hetal Shukla , Radhey Shyam Kaushal , Saloni Gautam , Himanshu Bapodariya , Mukund B Maliwad , Ajit K Gangawane

Page No : 117-152

With the growing world population, need for fresh water is increasing. World water resources are available in oceans and seas 97.5%. fresh water resources available is limited to 2.5% which is further contaminated by large range of pollutants such as the effluents from pharmaceutical industries, textile industries, food and dairy industries, mining industries agricultural waste, heavy metals, petroleum hydrocarbons, sewage waste etc. The composition of pharmaceutical wastewater is complex contains high concentration of organic matter, microbial toxicity, high salt, and difficult to biodegrade. Textile dyes wastewater is one of the main reasons behind severe pollution problems due to the greater demand for textile products and increase in production and applications of synthetic dyes. Agricultural wastewater includes pesticides, herbicides, fungicides, weedicides etc. which can be hazardous to human health, soil microbiota and aquatic microbiota. Heavy metals like uranium, mercury, lead, chromium, copper, iron etc. can cause a major environmental problem due to their toxicity and persistence in nature. To combat, bioremediation is an option that offers the possibility to destroy or render harmless various contaminants using natural biological activity. Further, nanoremediation – nanotechnology that depends on the use of nanomaterials to tackle and address the formidable challenges of 21st century as water pollution crisis. In-silico approach is a computational framework, potential to perform virtual screening of pollutants and helps to fulfill the gaps and address the flaws of convention bioremediation. A little effort has been made to put the entire literature review of these technologies in one refereed paper, our review paper is an attempt to compile the existing information on various treatment technologies viz. Bioremediation, Nanoremediation.
