Background Land snails, especially the chocolate banded snails, Eobania vermiculata (Muller 1774) are destructive pests of a wide range of field and vegetable crops, and biological treatment appears to be better alternative to the chemical snail control. Therefore, the goal of this work was to assess the molluscicidal activity of chitosan extracted...

This study compared microbiological and chemical methods used in astaxanthin extraction from the exoskeleton of the shrimp species Penaeus japonicus and Penaeus semisulcatus. The microbiological method was performed using Saccharomyces cerevisiae (bakery yeast) or Lactobacillus acidophilus (from yogurt), followed by solvent extraction with hexane a...

  • Jan 2022
Astaxanthin has been extracted in the current study using ecofriendly methods. Compared to the chemical method, a natural method using flaxseed oil at different time intervals, a biological method using standard fungal and bacterial probiotics (the fungal probiotics are Saccharomyces cerevisiae and Candida utilis, while the bacterial probiotics are...

... Khanafari et al. [20] used the Lactobacillus species Lactobacillus plantarum and Lactobacillus acidophilus for the extraction of astaxanthin from wastes of the shrimp species Penaeus semisulcatus. Also, Hamdi et al. [21] used Lactobacillus and Saccharomyces for the extraction of astaxanthin from byproducts of the crayfish Procambarus clarkia. Consequently, in the present research, Lactobacillus and Saccharomyces species were assessed as pretreatment for the extraction of astaxanthin from shrimp wastes as an ecofriendly alternative to the classical chemical method. ...
