ABSTRACT Recently, several articles have reflected on the existence of microorganisms in supporting life and health living creatures as beginning emergence microbiology literacy. In curriculum, understanding activity has been studied from pre-school, elementary school, middle school to college. The presence is often associated a cause disease. As result, most students know negative impact but not discovered fundamental role their lives. Special attention needs be given form effort strengthen...

Four bacterial isolates from Ranu Pani and Grati in east java had been revealed to be potentials produce IAA (PIS isolate), phosphate solubilizer (GPS cellulose hydrolysis (PSS isolate) and, amylum (PAS), two dominant Rani (PØD (GØD which were co-cultured with microalgae promoted growth, yet its taxonomical position has not clearly known. The aim of this study was identify those using 16S rRNA barcode. This research conducted by gDNA isolation, the sequence amplified 27F 1492R primers....

Abstract. Wadi is a sort of fermented fish product from Dayak tribe in Central Kalimantan. made with the addition lumu, sugar, and salt, for 7-10 x 24 hours. During fermentation process, there are microflora fish, lumu that play role process. Some species bacteria wadi process lipolytic Lactic Acid Bacteria (LAB). This research aims to: (1) identify LAB present wadi, (2) determine lipid hydrolysis index lactic acid clearance zone (3) which have highest ability to hydrolyze produce based on...

Ecosystems are composed of a large number diverse organisms that make up very complex interactions. Several studies have proven the influence abiotic factors on distribution bacteria in environment. Bacteria play an important role biogeochemical cycles and support productivity ecosystems. The environment causes need for research vertical bacteria. purpose this was to determine some lakes eastern Java. samples were taken from 3 East Java namely, Ranu Grati, Regulo, Pane. bacterial at 5...

Abstract. Ramadhani SI, Prabaningtyas S, Witjoro A, Saptawati TR, Rodiansyah A. 2020. Quantitative assay of Indole Acetic Acid-producing bacteria isolated from several lakes in East Java, Indonesia. Biodiversitas 21: 5448-5454. Biofuel is an alternative to fossil fuels that are environmentally friendly with low emissions. biomass microalgae, especially Chlorella vulgaris, has essential role biofuel production. Increasing microalgae was done by co-culture between and bacteria. This research...

Abstract Synergetic bacteria need to be explored which can accelerate the growth of microalgae have potential as oil producer related renewable energy. This research aimed analyze influence dominant from Ranu Pane (POD code), Grati (GOD Regulo (ROD and recombinant all sampling areas (PGR code) on Chlorella sp. in co-culture. Also, individual crosscheck was done by making co-interaction between predominant each biofuel producing ( sp.). The co-culture data species showed that had different...

Abstract Microalgae are microscopic autotrophic organisms which act as one of the biofuel-producing organisms. Ranu Grati is volcanic lakes located in Pasuruan, East Java. Human activities around waters responsible for eutrophication water quality. The aim this study was (1) described profile quality and microalgae community structure, (2) investigated potential a producer biofuels based on lipid content. Explorative research carried out by taking sample at depth 50 cm 5 stations. Water...

Microalgae are photosynthetic microorganisms that produce oil which has the potential for fuel production. This study aimed to determine effects of photobioreactor prototype shape, aeration period, and interaction between period form on growth co-culture Chlorella sp cells with bacteria. used a Completely Randomized Design (CRD).
