Xylanase enzyme production with ultrasonic assisted fermentation

Ultrasonic assisted fermentation has been shown to improve the product yield; however, less attention has been given to the xylanase production via ultrasonic assisted fermentation. The purpose of this study was to investigate the conditions in which ultrasonic has been employed to enhance fermentation reactions of interest to xylanase production. Previously, the xylanase production from locally isolated strain identified as Bacillus Badius was successfully carried out at an optimum condition. In this study, xylanase production was further explored by incorporated ultrasonic assisted fermentation. The study was conducted by varying the ultrasonic process parameters including treatment time and duty cycle. Within the studied range, the highest xylanase production was 9.21 U/mL at duty cycle of 10%, amplitude of 2% and treatment time of 25 min. However, the production was 21% lower than that the conventional fermentation. This is due to unoptimized condition of the ultrasonic assisted fermentation as compared to the conventional one. Ultrasonication at the best process parameters is an effective and feasible way to enhance xylanase activity. In the future, we are looking forward to optimize the ultrasonic assisted fermentation to maximized xylanase production

Descriptive Analysis of Students' CGPA: A Case Study of Universiti Malaysia Pahang

This study presents the descriptive analysis of students’ performance based on the cumulative grade point average (CGPA) of the entry grade and the CGPA achieved throughout their study duration until graduation. The data analysed are students from all bachelor degree programme at Universiti Malaysia Pahang of 2011, 2012 and 2013 cohorts. Components related to academic performance such as gender, entry qualification, CGPA (entry, all semesters), academic programme and cohort are analysed using the descriptive statistics. The results show that students from Sijil Tinggi Pelajaran Malaysia (STPM) performs very well academically with mean CGPA of 3.30 throughout the study period as compared to students from diploma (CGPA:2.97), matriculation (CGPA:2.88) or Sijil Tinggi Agama Malaysia (STAM; CGPA:2.71). The findings of the study can be used by the university’s administration to review intake policies and plan for the intervention program which could help improve the students’ academic performance
