This study has isolated,characterized,and identified potential plant growthpromoting rhizobacteria(PGPR)with multiple PGP characteristics(N_(2)-fixation,P-and K-solubilization,IAA,and siderophores production)from the rhizosphere BRIS soil of Acacia mangium.A total of 24 pure colonies were isolated and only 8 colonies were selected for further evaluation of the growth rate in 5%organic molasses medium supplemented with 2%KNO_(3).Based on the biochemical,potential PGP characteristics and growth performance,3 superior PGPR strains were selected and identified as Paraburkholderia unamae(UA1),Bacillus amyloliquefaciens(UA6),and Enterobacter asburiae(UAA2)by partial sequencing of the 16S rRNA *** selected bacterial strains either in single or mixed(UA1+UA6+􀀁UAA2)cultures have shown a significant biochemical estimation of the PGP *** strain has its own PGPR traits superiority with UA1 showing the best PGP characteristic followed by UA6 and *** use of mixed bacterial strains was beneficial as it showed the best performance in N_(2)-fixation,siderophores production,and significant effect on corn phenology,growth and yield compared to using a single *** types of microbes showed potential to be used as biofertilizer and should be exploited more.

Household Income and Expenditure Relationships： A Simultaneous Equation Approach

引用

Chinese Business Review 2011年第6期10卷 395-405页

作者： nik Hashim nik Mustapha Noorhaslinda Kulub Abd. Rashid Aslina nasir University of Malaysia Terengganu （UMT） Kuala Terengganu Malaysia

Income and expenditure are highlighted in this study as they currently affect the quality of life of the Malaysian society. In the Ninth Malaysia Plan （2006-2010） poverty eradication was emphasized as one of the socio-economic targets to uplift those poor households from the fast moving modern sectors of the economy. The primary objective of this paper is therefore to identify income and expenditure relationships among the households of the east coast of Peninsular Malaysia during the current economic downturn. Attempts to analyze household consumption as a share of total income and to identify factors contributing to household income and expenditure have become a topic of interest in literature. A substantial portion of household income devoted to productive loans characterizes the majority of Malaysians as the economy progresses to a more advance stage. A significant and strong relationship between income and types of household expenditure is explored from the socio-economic perspectives. Using primary data a system of simultaneous equations, namely the two stage least squares （2SLS） was applied. This paper identifies crucial variables associated with the income and expenditure. Some of these variables showing high correlation with the total expenditure are the housing loan, automobile loan and educational expenditure.

Objective:To determine the antibiotic resistance profile(ARP)of Staphylococcus(S.)aureus isolates and molecular typing of the methicillin-resistant ***(MRSA)isolates from Tuanku Mizan Armed Forces Hospital(TMAFH),Kuala ***:The ARP and presence of the pvl gene were determined for 209 *** isolates from clinical *** these,123 were methicillin-susceptible ***(MSSA)isolates and 86 were MRSA *** MRSA isolates were characterized using SCCmec typing and spa *** analysis was performed to compare the demographic data with the phenotypic and genotypic variables of the *** ***:No vancomycin-intermediate and-resistant ***(VISA and VRSA,respectively)were detected among the study *** MSSA isolates showed low resistance rates to all tested antibiotics,were commonly invasive(28/42,66.7%),and mostly harboured pvl(35/42,83.3%).Meanwhile,MRSA isolates showed high resistance to penicillin(86/86,100%),ampicillin(86/86,100%),sulbactam/ampicillin(86/86,100%),cefuroxime(81/86,94.19%),cefoperazone(76/86,88.37%),azithromycin(56/86,65.12%),and erythromycin(54/86,62.79%).The majority of MRSA isolates were of SCCmec type IVh(65/86,75.58%),spa type t032(55/85,63.95%),and grouped into spaCC-t022(66/85,77.65%).The t032 type was found to be associated with resistance traits to azithromycin and erythromycin(P<0.05).We also found several spa types that are typically associated with hospital-,community-,and livestock-associated MRSA co-existing in our MRSA ***:This study reflected the consistent absence of VISA and VRSA and corroborated the clonal shifting of MRSA isolates in the Malaysian MRSA isolates.

农业废弃物,如西米废弃物对土壤和水体的污染存在潜在威胁。为了减轻这一问题,本研究对3种不同处理的西米来源的废弃物的堆肥和西米来源的腐植酸的化学性质进行了研究。在大小为61.5×49×33.5cm的白色聚苯乙烯盒子里堆置60d,通过pH、总氮、有机碳、有机质、灰分、阳离子置换能力、磷、腐植酸等指标对其进行分析。所有处理都没有达到高温阶段。与处理T1、T3相比,处理T2(pH、总氮、有机碳、有机质、灰分、阳离子置换能力、磷、腐植酸)质量更好。T2的腐植酸产量也明显比其他两组高。T1和T3的堆肥特性相似。3种处理中的腐植酸化学特性在其他研究者报道的标准范围之内。与处理T1、T3相比,在60d里,T2处理更能有效地生产成熟、高质量的堆肥。
