Abstract

The research related to the isolation and partial characterization of indigenous fermenting bacteria from durian fruit (Durio zibethinus Murr.) was conducted from May to August 2012 in Laboratory of Microbiology, Biology Department, Andalas University. Experimental method was used and was descriptively analyzed. Ripe durian fruit contain indigenous fermenting as well as nonfermenting bacteria, that was recognized from halozone around the colony on modified GTA medium. Indigenous fermenting bacterias on the flesh of durian fruit have been characterized as Gram-positive, bacil, no endospores, motile and catalase positive. These isolates are proteolytics, amylolytics and cellulolytics and have no ability to hydrolyze fats and alcohol.Keywords : durian, fermenting, indigenous bacteria

Abstract

The study about the effect of acidity adjusting of industrial waste of tea production on the mycelium growth of brown oyster mushroom (Pleurotus cystidiosus O.K. Miller) was conducted from January to April 2013 in the Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. The aim of this study is to determine the effect of setting the acidity of tea production industrial waste and the mycelium growth of brown oyster mushroom. This research was designed by completely randomized design (CRD) with five treatments, which were pH 4, pH 5, pH 6, pH 7 and pH 8 in 5 replication. The results showed that the treatment of pH 8 and pH 7 on industrial waste of tea before weathering was optimum for the growth of mycellium (18 – 19,2 days) . Keywords: Acidity, waste of tea, Pleurotus cystidiosus, mycelium.

Abstract

A study on screening and characterization odf cellulolytic thermophylic bacteria from Sungai Medang hot spring was conducted on May to June 2012 using purposive sampling methods. This study aimed to find a cellulolytic thermophylic bacterium and to analyze its cellulolyties. Twenty eight cellulolytic thermophylic bacteria were isolated from Sungai Medang hot springs. The highest enzymatic activity (amylolytic and proteolytic activity) was shown by isolate MII2.1 from a location at which the temperature was 78oC. This isolate was characterized as an aerobic bacterium, gram negative and non motile. The form of colony was a circular margin, smooth shiny surface and elevation flat.Keywords: amylolytic, bacterium, cellulolytic, proteolytic, thermophylic

Abstract

A study about potential and characterization of native bacteria of intestinebroiler (Gallus gallus domesticus L.) as probiotic candidate of a broiler poultry product were conducted from December 2012 to March 2013 at Microbiology Laboratory, Department of Biology, Andalas University, Padang. This study aimed to obtainbacterial isolates and to describe morphological characters of each isolate of native bacteria as probiotic candidate for thebroiler.This study used an experimental method and analyzed descriptively. The results showed that rough material of intestine consisted of fermentative bacteria (57x107cfu/g), amylolitic (118x107cfu/g), cellulolytic (63x107cfu/g) and proteolytic bacteria (52x107cfu/g). Two isolates were potensial probioticcandidates; amylolytic bacteria and cellulolytic bacteria. The characteristics both probiotic candidates were gram negative, non-sporulating, positive catalase and motile.Keywords: Gallus gallus domesticus, intestine bacteria, characterization

Abstract

The research about the "Characterization of Natural Microflora From Cow Digestic Tract As Candidate For Cattle Feed Probiotics"  has been conducted from April to July 2013 in the Laboratory of Microbiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Andalas, Padang. This study aimed to obtain isolates  and the character of each isolate as a candidate to cattle feed probiotics. This study used an experimental method and analyzed descriptively. The result showed that the bacteria from cow digestive tract were Cellulolytic (110x107cfu/g), Fermentative (85x107cfu/g),  Amylolytic (31x107cfu/g) and Proteolytic (28x107cfu/g) bacteria. Two of  the probiotic candidate were bacill and coccus, both of them were Gram-negative and catalase positive.
