Abstract:
|
Marine yeast have been regarded as safe and showing a beneficial
impact on biotechnological process. It provides better nutritional and
dietary values indicating their potential application as feed supplements in
aquaculture. Brown et al. (1996) evaluated all the marine yeasts
characterised with high protein content, carbohydrate, good amino acid
composition and high levels of saturated fats. However, there is paucity of
information on marine yeasts as feed supplements and no feed formulation
has been found either in literature or in market supplemented with them.
This statement supported by Zhenming et al. (2006) reported still a lack of
feed composed of single cell protein (SCP) from marine yeasts with high
content of protein and other nutrients. Recent research has shown that
marine yeasts also have highly potential uses in food, feed, medical and
biofuel industries as well as marine biotechnology (Chi et al., 2009; 2010).
Sajeevan et al. (2006; 2009a) and Sarlin and Philip (2011) demonstrates
that the marine yeasts Candida sake served as a high quality, inexpensive
nutrient source and it had proven immunostimulatory properties for
cultured shrimps. This strain has been made part of the culture collection of
National Centre for Aquatic Animal Health, Cochin University of Science
and Technology as Candida MCCF 101. Over the years marine yeasts have
been gaining increased attention in animal feed industry due to their
nutritional value and immune boosting property.Therefore, the present study was undertaken, and focused on the
nutritional quality, optimization of large scale production and evaluation of
its protective effect on Koi carp from Aeromonas infection |
