Abstract

ABSTRACT: The mangrove endophytic bacterial isolate Scyphiphora hydrophyllacea has antimicrobial capabilities and also has other bioactive compounds to be developed in the field of biotechnology. The aim of this study was to identify the endophytic bacterial isolate SH 14 obtained from the S. hydrophyllacea mangrove based on 16S rDNA sequence analysis. Molecular-based identification of bacteria, namely DNA amplified by Polymerase Chain Reaction (PCR) using primers 27F and 1492R and has a gene amplification of 1481 bp. Sequence data analyzed using the BLAST program showed that isolate SH 14 had a homology level of 99.43% with Brevibacillus brevis. This similarity value is a reference in determining bacterial identification, where bacteria are categorized as the same species if they have a similarity of 99%.

Abstract

ABSTRACT: This study aimed to identify indigenous bacterial isolates producing Amylase ezyme from sago starch from Poom, Yapen Islands, using the 16S rDNA sequence molecular method. The isolates identified were IA4 and IA8, which exhibited the highest values of assimilase enzyme activity. Bacteria were identified based on DNA amplification using Polymerase Chain Reaction (PCR) with primers 27F and 1492R. Based on the results of molecular identification, the similarity index of Isolate IA4 and Bacillus cereus D21 is 97.80%, while isolate IA8 had a similarity index of 99.79% with Alcaligenes faecalis Y5. Therefore, the amylolytic bacterial isolates were named Bacillus cereus strain IA4 and Alcaligenes faecalis strain IA8.

Abstract

Gold mining in Village Warmanen, Sausapor District, Tambrauw Regency, has led to environmental pollution by heavy metals, one of which is copper (Cu), which has the potential to damage soil ecosystems and inhibit agricultural productivity. This research aims to isolate indigenous bacteria from former gold mining soil in Warmanen, test their ability to reduce Cu concentration through bioleaching technology, and identify the most promising bacterial isolates. The research method included soil sampling from the contaminated location, isolation and purification of bacteria. The bioleaching capability test was conducted by incubating eight bacterial isolates with copper-containing soil samples for 21 days on a laboratory scale. The decrease in Cu concentration in pellet fractions was analyzed using Atomic Absorption Spectrophotometry (AAS). The results showed that the bioleaching process using indigenous bacteria was effective in reducing Cu concentration, especially in the solid (pellet) fraction of the soil. The accumulation of 3 bacterial isolates showed the highest potential on the 7th day, namely PW 1, PW 3, and PW 8, the isolate with the highest Cu accumulation was PW 1 with an accumulation of 0.30%
