The global sponge & scouring pads market size was valued at USD billion in Growing demand for appropriate cleaning pads for different types of objects as they are effective on heavy as well as lightly soiled items is a key driving factor.

      Aspects of Sponge Biology is the result of a symposium about sponge biology held in Albany, New York in May The symposium not only presents investigations, but also problem areas in the field of sponge biology. This book therefore shows that sponges are a very challenging and untouched subject area for future Edition: 1. Sponges can reproduce in a variety of ways, both asexually and sexually. Asexual methods of reproduction include: the growth of stolons that develop into new individuals; a bud separating from the parent sponge and creating a new sponge elsewhere; and the simple act of parts of a sponge breaking of and establishing in a new location.

      The global sponge and scouring pads market is expected to post a CAGR of over 3% during the period , according to Technavio. Sponges, the members of the phylum Porifera (/ p ə ˈ r ɪ f ər ə /; meaning "pore bearer"), are a basal Metazoa (animal) clade as a sister of the Diploblasts. They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like mesohyl sandwiched between two thin layers of branch of zoology that studies Kingdom: Animalia.

Sponges (phylum Porifera) are known to be very rich sources for bioactive compounds, mainly secondary metabolites. Main efforts are devoted to cell- and mariculture of sponges to assure a sustainable exploitation of bioactive compounds from biological starting material.

These activities are flanked by improved technologies to cultivate bacteria and fungi which are associated with the sponges. Industry Outlook.

Sponge Industry Scribner's Magazine Although sponges, in one form or another, are among the most common articles of domestic use, it is doubtful if one person in ten thousand of those who are familiar with the appearance of a sponge could tell where it comes from, or how it is procured; certainly most of them would hesitate before venturing to name the natural kingdom to which it belongs.

History. More than species of sea sponges live in oceanic and freshwater habitats. Sponge fishing historically has been an important and lucrative industry, with yearly catches from years to regularly exceeding tonnes and generating over 1 million U.S.

dollars. However, this demand for sea sponges has seen catch rates peak and in the demand for bath sponges was 2, Tube sponges, or demosponges, are supported by a framework of spongin, a material similar to keratin, the substance in our fingernails.

They filter food from water drawn in through pores in the colony wall. The water exits through an opening called an osculum. Special cells called collar cells help to. The growth of sponge management systems market is primarily driven by increasing prevention and control measures during surgical procedure.
