Abstract

Oil degradation bacteria can be found in various habitats in the marine environment including in the waters around the harbor. This study aims to isolate the oil degrading bacteria from waters around the port of Bengkalis and test its ability to degrade crude oil. Isolation of the degrading bacteria has been done from February to April 2017 at the Marine Microbiology Laboratory, Department of Marine Science, Faculty of Fish-eries and Marine University of Riau. The amount of oil degrading bacteria ranges from 0.2 x 105 to 8.9 x 105 CFU/ml. The isolation result was obtained by 10 isolates of oil degradation bacteria, ie BM1a, BM1b, BM1c, BM1d, BM7a, BM7b, BM7c, BM7d, BM14a and BM14b. Identification based on morphological, physiological and bio-chemical characteristics of each isolate, all isolates were round and elevated, six were white in color, three were yellow, one cream-colored isolate, eight isolates with slip-pery edges and two isolates with periphery waves, seven isolates were indol positive, two isolates produced H2S, four isolates were methyl red positive, all isolates were motile, capable of fermentation of glucose and sucrose in sugar test, able to ferment citrate, positive catalase and Gram negative bacteria. For degradation test only five bacterial isolates were selected of BM1a, BM1b, BM1c, BM7a and BM7d. The highest degradation at 1% concentration was indicated by isolate BM1a, the highest degrada-tion at 2% and 3% concentrations was indicated by BM1c isolate. Therefor, bacteria isolate capable of degrading the highest crude oil was BM1c.

Abstract

Grouper fish has a fairly high economic value, especially in Asiancountries, namely Hong Kong, Singapore, Taiwan and China. High marketdemand. On aquaculture, is one important component of fish feed that plays animportant role in the cultivation. Application of probiotics in aquaculture fish feedhas not been done yet in the Fisheries sector. The research was conducted inOctober 2008, Grouper is used as the intestines and stomach samples were takenas a source of probiotics, whereas pathogenic bacteria obtained from thecollection of marine microbiology laboratory of Faculty of Fisheries and MarineRiau University. From the isolation of bacterial strains found 11 strains that havethe potential as probiotics, then proceed to the molecular test by using rDNA16 s.Which is obtained two strains of probiotic bacteria Bacillus cereus and the speciesof bacteria Strenotrophomonas maltophilia. The test results found that theantagonist Bacillus cereus isolates to inhibit the growth of pathogenic bacteriaAeromonas sp and two species of Vibrio sp. While the bacteriaStrenotrophomonas maltophilia showed no antagonism against pathogens.

Abstract

Tujuan dari penelitian ini adalah menguji daya hambat ekstrak kuda laut(Hippocampus spinosissimus) terhadap pertumbuhan bakteri Vibrio alginolyticus.Penelitian ini dilakukan pada bulan Desember 2016 sampai Januari 2017 di LaboratoriumMikrobiologi Laut Jurusan Ilmu Kelautan, Universitas Riau. Ekstrak etanol kudalaut memiliki kandungan kimia steroid/triterpenoid, saponin dan glikosida sertamemiliki efek sitotoksik Uji daya hambat dilakukan dengan metode eksperimen menggunakanempat konsentrasi ekstrak (100%, 50%, 25% dan 12,5%). Dari hasil penelitianyang dilakukan ditemukan bahwa rata-rata diameter zona daya hambat ekstrakkuda laut tertinggi terdapat pada konsentrasi 100% (3,67 mm) sedangkan yang terendahterdapat pada konsentrasi 25% (0,73%). Ekstrak kuda laut mampu menghambatpertumbuhan bakteri V. alginolyticus dengan potensi lemah dengan nilai rata-rata diameterzona daya hambat <5 mm. Ekstrak kuda laut cenderung bersifat bakteriostatik.

Abstract

The research was conducted from October until Desember 2018 at the Laboratories of Marine Chemistry and Marine Microbiology, University of Riau and Integrated Chemical Laboratory, University of Muhammadiyah, Riau. The Purpose of this research was to determine the inhibition of Xylocarpus granatum extracts on the growth of pathogenic bacteria (P. aeruginosa, E. coli and V. alginolyticus). Samples used for were leaves, fruits, and rods extract of X. granatum  andthe extacts was preferred different at concentrations 100%, 50%, 25% and 12,5%. The result showed that  the highest concentration at 100 %, rod was the best extracts to against the growth of pathogenic bacteria and the antimicrobial compound could inhibit thr growth of pathogenic bacteria (P. aeruginosa, E. coli and V. alginolyticus) with intermediate ability with clear zone diameter between 0,3 – 10 m

Abstract

Blood clams are soft-bodied animals that live sessile and obtain food by filtering (filter feeders). This results in many microorganisms accumulating in the body of the blood clams, one of which is the coliform bacteria group. Coliform bacteria are divided into two types, namely fecal coliform and non-fecal coliform. Fecal coliform comes from animal and human feces, such as Escherichia coli. According to SNI 01-7388-2009, the MPN value of E. coli bacteria for fresh Mollusca, Crustaceans, and Echinodermata is <3/g. This study aimed to calculate the density of E. coli bacteria in blood clams. This study was conducted from December 2024 to February 2025. Sampling was conducted at the lowest ebb with one transect consisting of 3 plots measuring 1 × 1m². The MPN method is a method for analyzing coliform bacteria and E. coli. The results of the estimation test obtained at station 1, namely the Tebing Dian Beach Area, ranged from 7-10 MPN/g with an average of 12.6 MPN/g and station 2, namely the "Cinta Mangrove" Tourism Area, ranged from 4-15 MPN/g with an average of 10 MPN/g. While the results of the estimation test obtained at station 1 ranged from 3-4 MPN/g with an average of 2.3 MPN/g, stations 2 ranged from 3 MPN/g with an average of 1.0 MPN/g. These results indicate that the abundance of E. coli bacteria in blood clams does not exceed the quality standards set based on SNI 01-7388-2009
