Exploration of the Microbial Diversity of Caves in the Philippines and its Biotechnological Potential: Bacterial Biofilm Formati

submitted by: UP Los Baños
A report on the UPLB Basic Research Program funded study to conduct initial assessments of microbial diversity of caves in Polillo Island, a Philippine Biodiversity Conservation Priority Area (PBCPA). Among the specific objectives are to: 1.) collect biofilm samples from cave environs (streams, pool of standing water, underwater passages, dripping water and rocks) of Mapanghe and Bulalon Caves in Polillo Islands, 2.) isolate, purify and identify bacterial species, 3.) conduct and monitor in...

Microbial Inventory Research Across Diverse Aquatic LTERs (ASM Working Group Part 2/4)

submitted by: LTER_NetworkOffice_is
The MIRADA LTERs project (see working group materials) is an NSF-funded Microbial Biodiversity Survey and Inventory across all 13 of the major aquatic (marine and freshwater) Long Term Ecological Research (LTER) sites. The long-term objective of our study is to document and describe baseline diversity and relative abundance data for both common and rare members of microbial communities located in aquatic LTER sites and to relate this diversity to the underlying physical and chemical...

International Soil Metagenome - Sequencing Project

submitted by: dougramsey
Soil is often considered to be one of the main reservoirs of microbial diversity on the planet. This diversity could provide a range of information about the origins of microbial functional diversity as well as novel genetic resources. However, our historical inability to cultivate the majority of soil bacteria has hampered our understanding and exploitation of this large diverse community (more than 95% are often considered inaccessible through traditional culture techniques). Over the last...

A Genomic Encyclopedia of Bacteria and Archaea (GEBA) and the Search for the Dark Matter of the Biological Universe

submitted by: dougramsey
There is a glaring gap in microbial genome sequence availability – the currently available genome sequences show a highly biased phylogenetic distribution compared to the extent of microbial diversity known today. This bias has resulted in major limitations in our knowledge of microbial genome complexity and our understanding of the evolution, physiology and metabolic capacity of microbes. Although there have been small efforts in sequencing genomes from across the tree of life for...
