Alginate was recovered from Sargassum latifolium biomass using different conditions of alkali treatment.Box-Behnken experimental design was evaluated to study the influence of alkali:alga ratio, temperatureand time on alginate yield, and its molecular weight (MW) and mannuronic/guluronic acid ratio (M/G).The second-order polynomial equations were analyzed by appropriate statistical methods. Extractiontemperature and time were the most important factors during alginate alkaline extraction. MW andM/G ratio played an important role in controlling the reducing power of alginate. Increasing pH of thealginate solutions enhanced its reducing capacity, while thermal treatment showed a negative effect.Additionally, alginate exhibited good emulsion stabilizing capacities with diverse hydrophobic com-pounds. Emulsifying activity was less sensitive to temperature, ionic strength and more stable at acidicpH.

There is a growing demand for chitosan production from fungi as it provides superior physico-chemical properties over traditional crustacean sources. Chitosan was recovered from Aspergillus niger biomass using different conditions of alkali deproteinization and Box-Benhken experimental design was evaluated to study the influence of alkali concentration, temperature and time on chitosan yield, degree of deacetylation (DD) and molecular weight (MW). Chitosan with different physico-chemical properties was obtained under different combinations of extraction factors. Desirability function was then used to predict the best overall combinations of responses. The most desirable compromise allowed for the recovery of chitosan with a yield of 7.0% (w/w), DD 83.64% and MW 2.70 × 104 Da, which were in good agreement with the predicted values. The recovered chitosan exhibited a good hydroxyl radical scavenging activity and ferrous ions chelating ability reached to 82.40% and 87.23%, respectively. Additionally, it demonstrated good emulsion stabilizing capacities with different vegetable oils. The results suggest that fungal mycelia can be used as a promising source of chitosan with important physico-chemical properties suitable for several applications such as food, pharmaceutical, and cosmetic industries.

The main aim of the present is to obtain certain properties of generalized Rice’s matrix polynomials such as their matrix differential equation, generating matrix functions, an expansion for them. We have also deduced the various families of bilinear and bilateral generating matrix functions for them with the help of the generating matrix functions developed in the paper and some of their applications have also been presented here.
