Development of a Bioactive Food Additive for Controlling of Fungal Growth

Development of a Bioactive Food Additive for Controlling of Fungal Growth



Mauricio V. Cruz, Marcos A. Pereira-Junior, Karla A. Batista, Katia F. FernandesFresh foods have a great importance in human nutrition. However, they
are marketed with greatly reduced shelf life mainly due to fungal
spoilage. In this work, cell wall degrading enzymes produced by
Trichoderma asperellum T00 (TCWDE) were immobilized onto cashew gum
polysaccharide (CGP) in order to evaluate the potential use of this
material as food additive aiming to increase the shelf life by
inhibiting fungal growth. Results from factorial design (32) evidenced
that the best conditions for TCWDE immobilization was achieved with 20
min of reaction using 1 mmol L-1 of NaIO4. On these conditions it was
observed 91% of retention yield for NAGase (30.1 ± 0.38 U mL-1), 41% for
chitinase (0.67 ± 0.05 U mL-1), and 24% for β-1,3-glucanase (0.017±
0.001 U mL-1). CGP/TCWDE was effective for growth inhibition of
Aspergillus fumigatus and Penicillium sp. and the inhibition mechanism
seems to involve changes in the cell wall of those microorganisms.
Finally, the CGP/TCWDE presented high stability after drying,
maintaining enzymatic and biological activity after 200 days of storage
at room temperature (25 ºC).

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal

The Ecological Impacts of Light Pollution at Night-time a Mechanistic Appraisal Abdullahi MG, Roslan U, Kamarudin M. K. A. Artificial light at night and its negative consequences are of great interest in the fields of Ecology, Human Geography Astronomy, and Human Health. Most of the studies to date concentrated on the influences of light pollution has on our ability to view the night sky, on biodiversity, and ecosystems. Though, in recent years, with the use of new technologies sensors, which provide accurate information for determining of night lights at the area, most consideration were given for estimating artificial light at night within the urban areas. In this study, urban night lights within the cities of Nigeria was evaluated by monitoring data from the ground measurements using Sky Quality Meter (SQM-LU-DL) devices. Besides, the SQM was used at the zenith (upward direction) for maximum evaluating of artificial light at the sites. Differences in night sky bri...

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran

Studying the tendency of citizens to participate in the protection and development of land scape in Tehran Shadi Maleki, Abbas Mafi, Seyedeh Mahsa Hosseini Today, as an essential part and parcel of urban landscape that they play a major role in metabolism and create a lack of serious damage to urban life. This study performed to investigate the willingness of citizens to participate in activities to protect and develop landscapeof Tehran district 4. The research was descriptive and correlation method that is used for collecting information. The statistical population consisted of district 4 of Tehran. The sample size was determined 230 by using Cochrane method. A questionnaire was used to collect data. According to the research, 63.04 percent of citizens showed participation in a high level. Among the variables investigated how citizen participation in conservation and development of landscape, effective strategies to motivate citizens to participate,the reasons for la...

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin

Land Use Land Cover Change Detection by Using Remote Sensing Data in Akaki River Basin Adimasu Woldesenbet Worako   Land use land cover change (LULCC) is the result of the long time process of natural and anthropogenic activities that has been practiced on the land. GIS and remote sensing are the best tools that support to generate the relevant land use/cover change in the basin. This study was conducted in the Akaki River basin to detect land use land cover changes within the 30 years period (1985-2015) by using landsat imagery data acquired from the GCF. Supervised maximum likelihood algorithm classification were deployed to classify land use/cover into four prominent land use groups and data’s were processed by using ERDAS imagine 2014 and ArcGIS10.1 software. In the basin dominant LULC was agricultural land use which accounts around 56.28% and the second largest is built-up area by 31.51% and the rest, forest(11.9%) and water body(0.31%) coverage were takes t...
