Antifungal Activity Of Lactobacillus Plantarum Lab-C5 And Lab-G7 Isolated From Malaysian Fruits, Asma Saleh Elmabrok

Asma Saleh Elmabrok

Abstract Anthracnose disease for both seed and air borne and affects seed germination and plant vigor to a greater extent. Biological control by antagonistic microorganisms is widely recognized as a promising method for control plant diseases. This study reports the effectiveness of using lactic acid bacteria (LAB) cultures or their supernatant as a biological control against anthracnose disease in chilli caused by fungus Colletotrichum gloeosporioides. From 30 lactic acid bacteria isolated from different sources, seven isolates showed good inhibition activity against C. gloeosporioides by dual overlay method and well method. These LAB have antifungal activity grew between 10 and 45oC, …

Screening Of Lactic Acid Bacteria As Biocontrol Against (Colletotrichum Capsici) On Chilli Bangi, Asma Saleh Elmabrok Nov 2012

Screening Of Lactic Acid Bacteria As Biocontrol Against (Colletotrichum Capsici) On Chilli Bangi, Asma Saleh Elmabrok

Asma Saleh Elmabrok

Abstract: Chilli (Capsicum annuum L.) is one of the major crops, vegetables grown in Malaysia and belongs to family Solanaceae. Pepper is suffering from many illnesses caused by fungi, bacteria and virus. The fungal disease is both seed and air borne and affect the germination of seeds and plant vital to a greater extent. Biological control by antagonistic microorganisms is widely recognized as a promising method for control plant diseases. This study reports the effectiveness of using Lactic Acid Bacteria (LAB) cultures or their supernatant as a biological control against anthracnose disease in chilli caused by fungus Colletotrichum capsid. From …


Eight Is Enough?: The Ethics Of The California Octuplets Case, Scott Paeth Oct 2012

Eight Is Enough?: The Ethics Of The California Octuplets Case, Scott Paeth

Scott R. Paeth

The recent California octuplets case raises a number of important issues that need to be addressed in the context of the increasingly widespread practice of in vitro fertilization. This paper explores some of those issues as looked at from the perspective of protestant theological ethics and public theology, examining the moral responsibilities of the various participants in the process, both before and after the octuplets’ birth, including the mother, her doctors, the health care bureaucracy, the wider society, and the media. Each of these participants failed in significant respects to consider the ethical implications of the births in this complicated …

Efficacy Of Lactobacillus Plantarum Cs Cell And Their Supernatant Against Colletotrichum Gloeosporioides On Germination Rate Of Chilli Seeds, Asma Saleh Elmabrok Aug 2012

Efficacy Of Lactobacillus Plantarum Cs Cell And Their Supernatant Against Colletotrichum Gloeosporioides On Germination Rate Of Chilli Seeds, Asma Saleh Elmabrok

Asma Saleh Elmabrok

Abstract: Lactic Acid Bacteria (LAB) were isolated from different fermented fruits and vegetables and screened for antifllllgal activity against chilli phytopathogen Colletotrichum gloeosporioides. Seven LAB showed antifrmgal activity as observed in the dual overlay assay method. These LAB grew between 10 and 45°C, pH 4.4 and 9.6 (except 1 isolate), 6.5 and 18% NaCl. Fungi infected seeds from four species of chilli were evaluated for germination rate with and without LAB treatments. LAB isolated C5 showed good fungal inhibition and allowed good seed germination and was identified as Lactobacillus plantarum using API CH50L kit. The results indicate that C5 has …


Rapid Inversion: Running Animals And Robots Swing Like A Pendulum Under Ledges, Jean-Michel Mongeau, Brian Mcrae, Ardian Jusufi, Paul Birkmeyer, Aaron M. Hoover, Ronald Fearing, Robert J. Full Jul 2012

Rapid Inversion: Running Animals And Robots Swing Like A Pendulum Under Ledges, Jean-Michel Mongeau, Brian Mcrae, Ardian Jusufi, Paul Birkmeyer, Aaron M. Hoover, Ronald Fearing, Robert J. Full

Aaron M. Hoover

Escaping from predators often demands that animals rapidly negotiate complex environments. The smallest animals attain relatively fast speeds with high frequency leg cycling, wing flapping or body undulations, but absolute speeds are slow compared to larger animals. Instead, small animals benefit from the advantages of enhanced maneuverability in part due to scaling. Here, we report a novel behavior in small, legged runners that may facilitate their escape by disappearance from predators. We video recorded cockroaches and geckos rapidly running up an incline toward a ledge, digitized their motion and created a simple model to generalize the behavior. Both species ran …


Isolation And Identification Of Lactic Acid Bacteria With Antifungal Activity Against Anthracnose Disease, Asma Saleh Elmabrok Jul 2012

Isolation And Identification Of Lactic Acid Bacteria With Antifungal Activity Against Anthracnose Disease, Asma Saleh Elmabrok

Asma Saleh Elmabrok

Abstract: The objective of this study was isolation, identification of lactic acid bacteria from different source and testing their antifungal activity against phytopathogens fungi C. capsici and C. gloe osporio ides. The isolates were identified by their phenotypic and genotypic characteristics and their antifungal activity was performed by the overlay method. Seven LAB isolates were showed good antifungal activity against phytopathogens fungi and were grew at different temperatures, pH and NaCl. However, C5 and G7 have the ability to inhibit the growth of both target phytopathogens fungi compared to other isolates. C5 and G7 identified by API 50CHL kit as …

Antibacterial Activity Of Lactobacillus Acidophilus Strains Isolated From Honey Marketed In Malaysia Against Selected Multiple Antibiotic Resistant (Mar) Gram-Positive Bacteria, Mohamed Mustafa Aween, Asma Saleh Elmabrok

Asma Saleh Elmabrok

Abstract: A total of 32 lactic acid bacteria (LAB) were isolated from 13 honey samples commercially marketed in Malaysia, 6 strains identified as Lactobacillus acidophilus by API CHL50. The isolates had antibacterial activities against multiple antibiotic resistant’s Staphylococcus aureus (25 to 32 mm), Staphylococcus epidermis (14 to 22 mm) and Bacillus subtilis (12 to 19 mm) in the agar overlay method after 24 h incubation at 30 ◦C. The crude supernatant was heat stable at 90 ◦C and 121 ◦C for 1 h. Treatment with proteinase K and RNase II maintained the antimicrobial activity of all the supernatants except sample …
