Biodiversity and biological applications of marine actinomycetes—Abu-Qir Bay, Mediterranean Sea, Egypt

mycolabadmin

Researchers isolated bacteria called actinomycetes from the Mediterranean Sea in Egypt that naturally produce colorful pigments. They found that one specific bacterium (Streptomyces tunisiensis) produces a green pigment with promising anti-inflammatory properties similar to common pain relievers. By optimizing the growth conditions, the scientists increased pigment production by over 12 times, suggesting potential applications in medicine and industry.

The Application of Fungi and Their Secondary Metabolites in Aquaculture

mycolabadmin

Fungi can help solve several problems in fish farming. They can make plant-based fish feed more nutritious and easier to digest, boost fish immune systems and disease resistance without antibiotics, help fish feed float better in water, and clean up polluted water from fish farms. This makes aquaculture more sustainable and environmentally friendly while reducing costs for farmers.

Pigment Formation by Monascus pilosus DBM 4361 in Submerged Liquid Culture

mycolabadmin

Scientists studied how to produce natural yellow, orange, and red pigments from the fungus Monascus pilosus in liquid culture. They found that the type of sugar and nitrogen used in the fermentation significantly affects pigment production. Interestingly, glucose actually reduces pigment formation through a process called carbon catabolite repression. M. pilosus offers a safer alternative to other Monascus species because it does not produce the harmful toxin citrinin, making it suitable for use in food products.
