Food-borne diseases have always been a major concern to the consumers, food safety authorities and food industries. Hylocereus spp or Pitaya peels are normally treated as wastes and will be discarded during processing. In this study, the antibacterial activity of ethanol, chloroform and hexane extracts from Hylocereus polyrhizus (red flesh pitaya) and Hylocereus undatus (white flesh pitaya) pee...

Amylase is one of the most important enzymes in the world due to its wide application in various industries and biotechnological processes. In this study, amylase enzyme from Hylocereus polyrhizus was encapsulated for the first time in an Arabic gum-chitosan matrix using freeze drying. The encapsulated amylase retained complete biocatalytic activity and exhibited a shift in the optimum temperat...

The family Gasteropelecidae is composed of three genera and eight species. This study shows that Thoracocharax cf. stellatus has 2n = 52 chromosomes for both sexes. The five males studied showed 8 metacentric, 16 submetacentric, 4 subtelocentric, and 24 acrocentric chromosomes; the seven females showed only one submetacentric chromosome, belonging to pair 11, and one extra acrocentric chromosom...

Enteromyxum leei has been identified as the causative agent of emaciation disease in a wide range marine fish hosts. In this study, we aimed to determine effect parasitic infection species on starry flounder that were cultured aquaculture farms Jeju island Korea. As mortality olive Paralichthys olivaceus because E. increased, some attempted culture Platichthys stellatus, an alternative. Myxospo...

BACKGROUND Use of plant resources and ecosystems practiced by indigenous peoples of Mesoamerica commonly involves domestication of plant populations and landscapes. Our study analyzed interactions of coexisting wild and managed populations of the pitaya Stenocereus pruinosus, a columnar cactus used for its edible fruit occurring in natural forests, silviculturally managed in milpa agroforestry ...

Until 1994, only scarce research existed on these plants; however the worldwide interest in this novel fruit crop is evident, as numbers of pitaya-related publications have grown rapidly, especially during the past decade .There is a big confusion about both botanical and commercial names and there is a need to clear this point. herein, we attempt to review existing knowledge on the taxonomy, b...

One species of the genus Tanypus Meigen, 1803, T. punctipennis Meigen, 1818 was previously recorded from Japan. Herein Tanypus nakazatoi sp. nov. is described and figured based on all life stages. Tanypus kraatzi (Kieffer, 1913) is recorded for the first time from Japan, and all stages are redescribed and figured. Tanypus formosanus (Kieffer, 1912) sensu Niitsuma (2001) is recognized as T. kraa...

  Glyphosate, N–(phosphonomethyl) glycine, has been widely used to control agricultural weeds in the north of Iran. However, it is also supposed to have adverse effects on natural sturgeon population. The present study was undertaken to evaluate the acute toxicity of glyphosate to three different sturgeon species (Huso huso, Acipenser stellatus, and A. persicus) under laboratory conditions. Fis...
