Abstract

The conversion of agricultural land and plantation into an area with high human activity can affect the biodiversity contained in it. The biodiversity of a region can be surveyed and collect in a systematic database to know the wealth of flora and fauna resources within a certain period of time. The aim of this research is to identify and inventory the vegetation database of plant, which can then be used as one of the important information related to the environmental change that happened from time to time following the impact of the growing development expansion. This study was conducted within the campus of the Institut Teknologi Sumatra (ITERA) which is undergoing physical construction in the form of buildings, roads, and some retention basin. Data retrieval was done by direct observation using the cruising method. The observations of each species are documented, identified, recorded and arranged in the collection catalog.

Abstract

Indole Acetic Acid (IAA) is the important phytohormone for boosting plant-growth promotion. It is related with amino acid tryptophan as a precursor for building IAA. However some bacteria such as Bacillus sp. and Escherichia coli enable to produce IAA without L-tryptophan on culture medium via the tryptophan independent pathways. This study aims to determine the potential of indigenous Bacillus sp. and E. coli isolate in producing IAA via Trp-independent pathways (without L- tryptophan). The stage of this study consists of growing of isolate on liquid media without tryptophan and measuring the levels of IAA using Salkowsky method. Bacillus sp and Escherichia coli could produce IAA with the concentration of 0,0236 mmol/L and 0,024 mmol/L, respectively. The concentration of IAA produced by these bacteria is quite low because of their ability to synthesis IAA from the independent tryptophan pathway. The independent tryptophan pathway means these bacteria could synthesize IAA without using tryptophan as a precursor on their growth medium.
