Analisis metagenomicos de agua contaminada con cianuro.--En las muestras de agua contaminados con cianuro 17 filos fueron identificados, siendo Firmicutes (59.16%), Actinobacteria
(38.99%) los filos con mayor abundancia.

A systematic review points to higher Firmicutes and lower numbers and diversity of Actinobacteria

and evaluation of bioprocess for production of alkaline keratinase, Int.
In bovine livestock feces, Firmicutes dominated the microbiota, with 81.9% of all the reads, followed by Proteobacteria (9.6%), Bacteroidetes (5.4%), and Actinobacteria
(2.8%) (Rudi et al., 2012).
The counts of eight groups of microbes were determined, including organotrophic bacteria and actinobacteria
([10.sup.-4] and [10.sup.-5] kg DM of soil) and fungi ([10.sup.-3] and [10.sup.-4] kg DM of soil).
There was a predominance of phylum Firmicutes over Actinobacteria
; phylotypes Clostridales and Bacteroidales predominated over commensal Staphylococcus and Propionbacterium species.
Firmicutes was the dominant phylum in all samples (ranging from 89.3% to 98.8% of total reads), while Actinobacteria
was the second dominant group in most of the samples (0.6% to 7.9%).
Among these OTUs, the top phylum, based on the number of significant OTUs within the phylum, was Proteobacteria, followed by Firmicutes and Actinobacteria
. When we assessed differences in mean relative abundance of the families to which the 631 OTUs belong according to the four categories of current farming (no farming, crop farming only, animal farming only, both crop and animal farming), the top five families were Moraxellaceae, Clostridiaceae, Prevotellaceae, Propionibacteriaceae, and Bacillaceae (Table S8).
Microbiome varies from birth, as babies born naturally are covered with microbes such as bifidobacteria and lactobacilli, Bacteroides, Proteobacteria or Actinobacteria
, while those which come to the world through caesarean surgery are covered by microbes that normally exist on the skin of adults like E.coli, Clostridium difficile to the detriment of those mentioned above (3).
Dalisay is currently conducting a research on marine sediments in the NRCP-funded project, titled 'Marine Sediment-Derived Actinobacteria
: New Vista for Natural Products Discovered in the Philippines,' a three-year program.
