Opis:
Enzymes are increasingly used in the food industry, due to the fact that they allow to streamline many processes. They catalyse processes that require energy and are long-lasting. Mushrooms produce hydrolytic enzymes such as proteases, lipases and amylases. These enzymes are used in winemaking, brewing, confectionery and cheese production. Attempts have also been made to use paper industry enzymes such as laccase in the wine industry. The production of enzymes of animal origin is an expensive and complicated process, which is why they were interested in their production from microorganisms. This article attempts to review the current state of knowledge on the use of fungal enzymes in the food industry.

Opis:
The non-structural dengue virus (DNV) protein, DNV-2 NS2B/NS3 protease is a combination of two proteins as 2B and 3 and these two proteins in complex replicate faster during dengue fever. The objective of the present study was to detect hot spots and design of smart libraries for engineering protein stability, substrate specificity, tunnels and cavities as well as suitable mutability position of studied protein by using an online tool, HotSpot Wizard (version 3.0). The prediction results were obtained in output interface for functional hot spots, stability hot spots (structural flexibility), correlated hot spots and stability hot spots (sequence consensus) from the sequence string. It is concluded that the prediction of pocket and mutability of this protein can easily be identified the structural alternation especially in disease diagnosis and space for ligand binding site in pocket for the potential of new drug design. Moreover, this computational prediction is suggested to compare with experimental hotspots for studied protein in relation to therapeutic efficacies, which are lacking to prevent viral infection.

Opis:
In recent years, there has been a phenomenal increase in the use of alkaline proteases as industrial catalysts. The aim of this work was to isolate potent fungal strain from the agricultural field of Gulbarga region of India, for the production of alkaline protease by utilizing the agricultural by products viz, red and green gram and Bengal gram as substrate under submerged fermentation process. Optimization of fermentation process parameters such as substrate (Red gram husk, green gram husk and Bengal gram husk) utilization, utilization, temperature, pH and incubation period for alkaline protease production was carried out. The maximum production of alkaline protease by Trichoderma VPG 12 was found at pH 8, temperature 35 °C, incubated for 120 h. But the activity of the enzyme could also be seen in a wide range of pH (5-9) and temperature (20-40 °C). With all these properties, the strain can be considered for industrial grade production of alkaline protease.

Opis:
This research aims to investigate the effect of adding potassium diformate to commercial feed on the increase of absolute growth rate and the activity of protease enzyme. The research was conducted from July to October 2019 in the Aquaculture Laboratory Faculty of Fisheries and Marine Sciences, Padjadjaran University. The method applied in this research was an experimental method using a Completely Randomized Design (CRD), which consists of four treatments and four replications. The treatments were: (A) without addition of Potassium diformate (control), (B) addition of Potassium diformate by 0.3%, (C) addition of Potassium diformate by 0.5%, and (D) addition Potassium diformate by 0.8%. The test fish were 300 giant gouramis with 4-6 cm in length. The containers used in this research were 16 rearing aquaria with a size of 40 30 40 cm3. The density of studied giant gourami fingerlings was 10 fish per aquarium. The rearing period was 40 days. The feeding rate was 3% from biomass. Water quality parameters (temperature, pH, and dissolved oxygen), the absolute growth rate, feed conversation ratio and survival rate were observed every 10 days. The protease enzyme activities were observed at the end of the research. Data on the absolute growth rate, feeding conversion ratio, the characteristics of protease enzyme and survival rate were analyzed using the Analysis of Variance (ANNOVA) continued with Duncan’s Multiple Range Test at the level of 95%, while the water quality was analyzed descriptively. The results show that the addition of potassium diformate by 0.3% gave the best result with the absolute growth rate of 1.50%, feed conversion ratio of 2.70, protease enzyme activity by 634.2 μ/mL and survival rate of 100%.
