Abstract

Xylanase is the enzyme with prospec for hydrolysis hemicellulases. Many industry use xylanase thermostable. This processes require enzymes which are operationally stable at high temperature thus allowing e.g. easy mixing, better substrate solubility, high mass transfer rate, and lower risk of contamination. Thermophiles have often been proposed as sources of industrially relevant thermostable enzymes. Thermophilic bacteria, live at hot-springs, are can produced thermostable enzymes. In this work, we studied the bacteria strains isolated from water collected in the Sonai hot-springs of Southeast Sulawesi region and condition production enzyme. Screaning bacteria xylanolitic use semi-quantitative detection at agar plate with xilan, and quantitative detection activity enzyme. Result experinces in the 28 isolates screened, isolat IIA-3 (Pseudomonas sp.) showed the highest xylanase production. Organism efficiently used 2% rice straw as substrates. Pseudomonas sp. was used to hydrolyses rice straw at 50oC, agitation 150 rpm and pH 9.

Abstract

Fund is like blood flowing to all parts of the human body, if there is human blood deficiency therefore sooner or later death will be the result . Similarly toward education funding, regardless of the cost of all planned programs will likely not be operationalized. Problem of the high cost of higher education is perceived by the public on the one hand, and the desire to provide a better education on the other hand has always been a problem that still can not be resolved satisfactory . When we look at the history of the heyday of Islam, funding institutions apparently has got the most attention from the education providers and other parties that are not directly involved in it. While the pattern of management education in the classics are implemented in two ways: 1. Centralized systems, centralized point here is that education funding is planned and managed by bureaucrats (power authority), not by the institution concerned. All educational needs will be met by the government through the state treasury or the Bayt al-Maal. 2. Decentralized system is more flexible and participatory than centralized systems, which consist of the traditional pattern (the traditional pattern of the proceeds are typically used without a clear plan), and non-traditional pattern, this pattern is the antithesis of the traditional pattern, incoming funds managed by organizers of the institution, through a targeted plan according to the situation and condition of the institution concerned.
