The base of aquatic energy is initiated and concreted by plankton such as primary photosynthetic algae and consequently their immediate secondary grazers as zooplankton. The nutritional features of algae or phytoplankton are controlled by aquatic nutrients (e.g. nitrogen, phosphorus, silica and other essential minerals). Moreover, the biochemical content of zooplankton reflects their diet profiles (e.g. bacteria and algae). The promising and sustainable fisheries prospects are crucially subjective by nutritional quality and quantity of plankton (e.g. algal bloom). Additionally, both algae and zooplankton are efficient as auspicious biological tools for indicating the aquatic environments.

Abstract Algal bloom (AB) is a serious water environment problem in China, but it is still unclear how AB affects microorganisms with special functions (such as nitrogen-, phosphorus-, sulfur- and iron-related bacteria) at different AB stages. Samples of water and sediment were taken in the AB region and free algal bloom (FAB) region of Chaohu Lake at different AB stages, and the numbers of N-, P-, S- and Fe-related bacteria were determined by culture-dependent methods. Results showed that during the whole experiment, numbers of N-, P-, S-, and Fe-related bacteria in the AB region were significantly higher than those in the FAB region, especially at the AB outbreak stage. In the FAB region, numbers of above bacteria showed little variation with time. In the AB region, however, numbers of N-, S-, and Fe-related bacteria evidently changed as ‘Λ’-type with AB process. They presented upward trend at the AB formation stage and the initial stage of AB outbreak, and then showed downward trend. Numbers of P-related bacteria also showed similar trend as above bacteria, but they kept high level for long time at the AB outbreak stage. This study indicated that AB produced different effects on microorganisms with special functions at different AB stages.

Phytoextraction Potential

This study aimed to evaluate the effects of different concentrations of sodium on the phytoextraction of nutrients and nutritional quality of forages (P. purpureum Schum and C. dactylon Pers) grown in wetland system constructed for wastewater generated in cattle slaughterhouses (WGCS) treatment. The experiment was conducted in a randomized complete block design with three replications. The treatments were tested using 2 x 5 factorial scheme, as follows: two species of grass (P. purpureum Schum and C. dactylon Pers) and five concentrations of sodium in WGCS: 70, 100, 150, 200 and 250 mg L-1. The phytoextraction potential of nutrients and the nutritional quality of forages grown in pots simulating a wetland system constructed for WGCS with sodium concentrations were assessed in terms of the contents of the nutrients nitrogen, phosphorus, potassium, calcium, magnesium and sodium in leaf tissues. The accumulations of these nutrients in the produced forages were also evaluated. Both species presented different behaviors regarding their nutrient phytoextraction potentials. The nutritional quality was changed in the forages due to the cultivation in constructed wetlands. Forage C. dactylon Pers presented higher phytoextraction potential of sodium and potassium and P. purpureum Schum presented a higher nutritional quality.

Leaf Powder

Pasta was prepared by incorporation of Ocimum sanctum (Basil) for better textural and sensory properties. The pasta was incorporated with the leaf extract of Ocimum sanctum at different concentrations of control, 5, 10, and 15.The natural antioxidants present in the O. sanctum leaf powder that was incorporated in the fruit leather showed extended shelf-life over three months when compared with control, without any added preservative at ambient temperature. Also the nutritional stability of the product was studied under two flexible packages of polypropylene and polyester out of that the products packed in polypropylene showed better storage stability .
