Utilization of Ceramic Beads for Edible Mushrooms Cultivation

In recent years, mushrooms have been drawing much public attention as a source of development for medications and nutraceuticals because of their antioxidants, antitumors, and antimicrobial properties. And they are also becoming more essential to the human diet due to their nutritional value, high levels of protein and low levels of fat. Besides, for mushrooms can be cultivated with low cost and low usage of land compared to other agricultural products, many farmers and manufacturers are turning towards the cultivation of mushrooms.

In this study, the authors examined ceramic beads as a reusable material for cultivation of edible mushrooms. And 20 species of edible mushrooms were tested, which were obtained from the Mushpia Co. Limit., Fukuoka, Japan. Within the cultivation vessels, 70% were ceramic beads (diameter 1 cm) and 30% of the nutrient solution. Moreover, the control groups used several types of sawdust, wheat bran, and rice bran with the ratio of 8:1:1 as the substrate. Two sets of substrates were evaluated with the fruit bodies yield. And Identification of statistical differences within treatments was done by Analysis of Variance (ANOVA), followed by Tukey’s post hoc test. All the analyses were done with 0.05 significance levels.

The result indicated that there were 11 species that responded well with the ceramic bead substrate when compared to the traditional sawdust substrate with Agrocybe cylindrica and Pleurotus ostreatus performed the best adding 70 g more of the fruit bodies. Conversely, nine species responded poorly with the ceramic beads substrate with Auricularia polytricha performed the worst losing 120 g.

In conclusion, ceramic beads as a reusable material for substrates not only provide a clean and controllable environment for mycelium to colonize, but also deliver more aeration and water availability inside the cultivation vessels. And the application of the ceramic bead cultivation can be viewed as an alternative solution for producing Ophiocordyceps sinensis on the industrial level.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
